Stock Market Terminology: 100+ Terms Every Indian Investor Should Know

By Vinoth Kanna Published 17 August 2026 33 min read Guides · Education

Stock market terminology can make a simple idea sound needlessly difficult. A company earns money, investors decide what that stream of earnings may be worth, and buyers and sellers meet on an exchange. Around that basic process sits a vocabulary of accounts, orders, ratios, corporate actions and risks.

This Indian stock market glossary explains those words in plain English. It covers the basic stock market terms beginners meet, then adds the language used in annual reports, IPO documents and trading screens. It is designed for investors, not for an exam: each definition tells you what the term means and, where useful, what it changes in a real decision on NSE or BSE.

You do not need to memorise the whole list. Bookmark it, use the alphabet links, and return whenever a broker screen, annual report, IPO document or market headline uses an unfamiliar phrase.

One warning before the glossary: knowing a term is not the same as understanding an investment. A low P/E, an upper circuit or an oversubscribed IPO can sound positive while hiding important risk. Treat every metric as the start of a question, not the end of one.

The 12 terms to learn first

If you are completely new, start here before using the A-to-Z reference.

Term	Plain-English meaning	Why it matters
Share	A unit of ownership in a company	You are buying part of a business, not a number on an app
NSE / BSE	India’s main stock exchanges	They are marketplaces where orders meet
SEBI	India’s securities-market regulator	It regulates exchanges and registered intermediaries
Demat account	Electronic account that holds securities	It is where delivered shares are recorded
Trading account	Account used to place buy and sell orders	It connects you to an exchange through a broker
Market capitalisation	Share price multiplied by shares outstanding	It measures equity value better than share price alone
Market order	An instruction to trade at the best available price	Execution is prioritised; the final price is not guaranteed
Limit order	An instruction with a maximum buy or minimum sell price	Price is controlled; execution is not guaranteed
P/E ratio	Share price divided by earnings per share	It is one starting point for judging valuation
Volume	Quantity traded during a period	It helps you judge participation and liquidity
Dividend	Cash a company distributes to eligible shareholders	It is a return of capital, not free extra money
Volatility	How widely and quickly prices move	It affects both opportunity and the chance of a damaging loss

For the full mechanics behind those terms, read how to start investing in the Indian share market. The definitions below are a desk reference for everything that comes next.

How the Indian market stack fits together

Several organisations can appear in one transaction. They do different jobs.

Market participant	Main role	What an investor should check
SEBI	Regulates the securities market and registered intermediaries	Registration status, investor alerts and grievance routes
NSE / BSE	Provide the venue and systems where orders are matched	Symbol, series, price band, filings and trading notices
Broker	Sends your orders to the exchange and provides the trading account	Registration, tariff, risk policy and contract note
Clearing corporation	Calculates obligations and supports completion of settlement	Usually works behind the scenes; its rules shape margins and settlement
NSDL / CDSL	Hold securities within the electronic depository system	Depository shown in your demat details and statements
Depository Participant	Opens and services your demat account	DP charges, instructions, alerts and account details
Issuer / RTA	Maintains issuer records and processes investor services and corporate actions	Exchange notices, entitlement details and official contact channel

A

Alpha. Return above a chosen benchmark or model expectation. If a portfolio gains 14% while its appropriate benchmark gains 11%, the simple excess return is three percentage points; whether that is skill depends on risk, costs and the period measured.
Annual report. A company’s yearly account of its financial statements, business, risks, governance and management commentary. Read the exchange-filed report rather than relying only on a summary or ratio website.
Annualised return. A return expressed as a yearly rate so periods can be compared. It is not simply the total gain divided by years when compounding is involved; CAGR or XIRR may be the right calculation.
Arbitrage. An attempt to profit from a temporary price difference for the same or closely related asset in two places. The visible gap is not guaranteed profit after timing, funding, taxes, fees and execution risk.
Ask price (offer price). The lowest displayed price at which a seller is currently willing to sell. A market buy order usually meets the available asks, potentially across several price levels.
ASBA. Application Supported by Blocked Amount. In an IPO application, the bank blocks the application money and debits only the amount required after allotment, rather than sending the full sum away first.
Asset allocation. How a portfolio is divided among equity, debt, cash, gold and other assets. For most households, this decision influences risk more than choosing between two similar large-cap shares.
Average price. The quantity-weighted cost of multiple purchases. Buying 10 shares at ₹100 and 20 at ₹130 produces an average cost of ₹120, not ₹115, before charges.

B

Bear market. A sustained phase of broadly falling prices and weak sentiment. A 20% decline is a common market convention, not a law or a guarantee that the bottom has arrived.
Benchmark. The index or reference portfolio used to judge performance. A small-cap fund should not claim skill merely because it beat a large-cap index during a small-cap rally; the comparison must be appropriate.
Beneficial owner (BO). The investor entitled to the rights and benefits of securities held in demat form. The depository is recorded as the registered owner for electronic holdings, while the actual investor remains the beneficial owner.
Beta. A historical estimate of how sensitively a security moved relative to a market benchmark. A beta above one suggests larger past moves, but it does not predict the direction or size of the next move.
Bid price. The highest displayed price a buyer is currently willing to pay. A market sell order meets available bids, so a thin order book can produce a lower fill than the last traded price.
Bid-ask spread. The gap between the best bid and best ask. A ₹99 bid and ₹101 ask means a ₹2 spread; wider spreads are an immediate trading cost and often signal weaker liquidity.
Block deal. A large transaction executed through a designated exchange window under applicable rules. It may reveal institutional activity, but it does not by itself prove that the buyer or seller is right about future value.
Bonus issue. Additional shares issued to existing shareholders in a stated ratio without a cash payment. The share count rises and the price adjusts economically, so a 1:1 bonus does not instantly double your wealth.
Book building. The IPO process in which bids across a price band help determine the issue price. Strong demand can influence pricing and allotment, but oversubscription does not establish long-term business quality.
Book value. Assets minus liabilities attributable to equity holders. Book value per share divides that amount by shares outstanding; it is usually more informative for asset-heavy businesses and lenders than for brand- or software-led companies.
Broker. A SEBI-registered intermediary through which an investor places exchange orders. The broker operates the trading interface; delivered securities are held through the depository system, not as the broker’s own property.
BSDA. Basic Services Demat Account, a limited-service account intended to reduce maintenance costs for eligible individual investors with holdings within prescribed limits. Eligibility and charges can change, so check the current depository or DP schedule.
Bull market. A sustained phase of broadly rising prices and optimistic sentiment. A bull market can contain sharp corrections, and a rising index does not mean every listed company is improving.
Buyback. A company repurchasing some of its own shares under a regulated process. It can reduce shares outstanding, but value depends on the price paid, funding source, resulting balance sheet and current tax treatment.

C

CAGR. Compound annual growth rate: the constant yearly rate that connects a starting value to an ending value. It smooths the path, so two investments with the same CAGR may have experienced very different volatility.
Call option. A contract giving the buyer the right, but not the obligation, to buy an underlying asset at a strike price by or on specified terms. The buyer pays a premium that can expire worthless.
Capital gain or loss. The difference between sale value and eligible cost, adjusted as tax rules require. An unrealised gain exists only on paper; selling can create a taxable event.
Cash flow from operations (CFO). Cash generated or consumed by core operations. Compare it with profit across several years: persistent profit without supporting operating cash flow deserves investigation.
Circuit breaker. An index-based market-wide trading halt triggered by specified moves in the Sensex or Nifty 50. It is different from the price band applied to an individual security.
Circuit filter (price band). The permitted daily price range for a security subject to that mechanism. Reaching the upper or lower limit does not tell you fair value, and a locked circuit can make exiting impossible at the displayed price.
Clearing corporation. The market institution that determines obligations and supports settlement between trading members. It sits between trading and final movement of funds and securities.
Closing price. The exchange-determined official price for the end of a trading session, calculated under its methodology. It may differ from the final tick you happened to see on a chart.
Corporate action. An event initiated by a company that affects its securities or holders, such as a dividend, split, bonus, rights issue, merger or buyback. Ex-dates and record dates determine how entitlements are handled.
Coupon. The interest payment on a bond, usually stated relative to face value. A bond’s coupon rate and its current yield are not necessarily the same when the bond trades away from face value.
Credit rating. An agency’s opinion on an issuer’s or debt instrument’s credit risk. It is not a guarantee, can change, and does not measure the upside of an equity share.

D

Day order. An order valid for that trading day. If it does not execute, the exchange or broker system cancels it at the end of the applicable session.
Debt-to-equity ratio. Total debt divided by shareholders’ equity, subject to the chosen definition. A value of 0.5 means ₹0.50 of debt for each ₹1 of equity; compare companies within similar business models.
Delisting. Removal of a security from exchange trading, voluntarily or compulsorily. Delisting does not automatically mean the shares cease to exist, but liquidity, exit rights and valuation can change sharply.
Delivery trade. A purchase held beyond the day and settled into the demat account, rather than bought and sold intraday. Delivery reduces trading frequency; it does not make a weak company safe.
Demat account. An account that records securities electronically. It holds investments; it is distinct from the trading account used to submit orders and the bank account used for money.
Dematerialisation. Conversion of eligible physical security certificates into electronic balances in a demat account. The reverse process is called rematerialisation.
Depository. A market infrastructure institution that holds securities in electronic form and enables transfers. India’s two securities depositories are NSDL and CDSL.
Depository Participant (DP). The intermediary through which an investor accesses a depository, often a broker or bank. You open and service the demat account with a DP, not by sending every request directly to the depository.
Derivative. A contract whose value is linked to an underlying share, index, currency, commodity or other asset. Leverage and expiry make derivatives materially different from simply owning a share.
Dilution. Reduction in an existing shareholder’s percentage ownership or per-share claim when additional shares or convertible instruments are issued. A fund-raise can still create value if the new capital earns an adequate return.
Dividend. A distribution a company declares for eligible shareholders. The company’s cash falls when it pays, and the market price can adjust around the ex-date; a dividend is not free money.
Dividend yield. Annual dividend per share divided by current share price. A 6% trailing yield can be misleading if the dividend was exceptional or the business can no longer support it.
DP charge. A depository-participant fee commonly charged when securities are debited from a demat account. It can apply per security rather than per share, so inspect your DP’s tariff and contract notes.

E

Earnings. Profit attributable to a company or its shareholders for a period. Always ask which earnings figure is being quoted: operating, before tax, after tax, standalone, consolidated, reported or adjusted.
Earnings call. A management discussion with analysts and investors after results. It can add context, but management commentary should be checked against filings, cash flow and later delivery.
EBITDA. Earnings before interest, tax, depreciation and amortisation. It is an operating proxy, not cash flow: it ignores capital expenditure, working-capital needs, financing and tax.
EPS. Earnings per share, usually profit attributable to equity holders divided by a weighted average share count. Diluted EPS also reflects instruments that may become shares.
ETF. Exchange-traded fund: a pooled investment whose units trade on an exchange. Its market price can differ slightly from net asset value, and liquidity and tracking error still matter.
Equity. Ownership interest in a business after liabilities. In a balance sheet it is assets minus liabilities; in markets, equity securities give investors a residual claim rather than a fixed repayment promise.
Ex-date. The date from which a security trades without an upcoming entitlement such as a dividend. Buying on or after the ex-date normally does not give you that announced benefit; check the exchange notice.
Exceptional item. A material item presented separately because it is unusual in size or nature. Removing every inconvenient expense as “one-off” can overstate normal earnings, so read the notes.

F

Face value. The nominal value assigned to a share in the company’s capital records. It is used in matters such as splits and some dividend announcements, but it does not show whether a ₹20 or ₹2,000 market price is cheap.
Free cash flow (FCF). A common shorthand for operating cash flow minus capital expenditure. Definitions differ, so reconcile the calculation before comparing companies.
Free float. Shares reasonably available for public trading after excluded strategic or locked holdings. Free-float market capitalisation is used to weight major Indian indices.
Fundamental analysis. Studying a company’s business, financial statements, governance, industry and valuation to estimate quality and value. A ratio screen narrows the field; it does not complete the analysis.
Futures contract. A standardised derivative obligating parties to transact or settle an underlying asset at specified terms. Daily mark-to-market and leverage can generate losses larger and faster than cash-equity investing.
F&O. Futures and options. This exchange segment uses contracts, margins and expiries; it should not be treated as a faster version of buying delivery shares.

G

Gap up or gap down. When a security opens materially above or below the previous session’s trading range or close. News and overnight orders can cause a gap, but the opening move need not continue.
G-sec. Government security issued by India’s central or state governments. G-secs carry sovereign credit characteristics but still face interest-rate and market-price risk when sold before maturity.
Good Till Triggered (GTT). A broker-provided instruction stored until a chosen trigger condition is met, after which an order may be sent. It is not a universal exchange order type, and triggering does not guarantee execution.
Governance. The systems and behaviour through which a company is directed and controlled. Auditor changes, related-party transactions, capital allocation and treatment of minority shareholders can matter more than a seemingly low valuation.
Growth stock. A company priced partly on expectations of above-average future growth. Growth can be genuine while the share remains a poor investment if the purchase valuation assumes too much.

H

Haircut. The percentage reduction applied to the market value of pledged collateral when calculating usable collateral. A ₹1 lakh holding with a 20% haircut may provide only ₹80,000 of collateral value.
Hedging. Taking a position intended to reduce a specific risk in another position. A hedge has a cost and can introduce basis, liquidity or execution risk; it does not make a portfolio risk-free.
Holding period. The time between acquisition and disposal. It affects strategy, turnover and tax treatment, whose thresholds and rates should always be checked for the relevant year and instrument.
52-week high/low. The highest or lowest traded price over roughly the preceding year. It is an anchor, not valuation: a stock can be expensive below its high or attractive above an old high.

I

Index. A rules-based basket used to represent a market or segment. You cannot buy a calculation directly, but you can invest through a fund or derivative designed to track it.
Index fund. A mutual fund that seeks to track an index before fees and tracking difference. Check which index, expense ratio, tracking record and portfolio concentration rather than assuming all index funds are alike.
Insider trading. Trading while possessing unpublished price-sensitive information, or unlawfully communicating such information, under the applicable securities rules. Legal trades disclosed by insiders are different from prohibited insider trading.
Institutional investor. An organisation investing pooled or institutional capital, such as a mutual fund, insurer, pension fund or foreign portfolio investor. Institutional buying is evidence of demand, not proof of value.
Intraday trading. Opening and closing a position within the same trading day. Brokerage, taxes, spread, slippage and forced square-off rules all affect the result; there is no overnight ownership from a completed round trip.
IPO. Initial public offer: a company’s first public issue of shares. It may include newly issued shares, which fund the company, and an offer for sale, whose proceeds go to selling holders.
ISIN. International Securities Identification Number, a unique 12-character identifier for a security. Different classes or forms of securities from the same issuer can have different ISINs.
Issue price. The price at which securities are allotted in an issue. A listing premium or discount compares the exchange price with this number; it says nothing certain about later returns.

J

Joint demat account. A demat account held in more than one name and a specified order. It is not an “either-or-survivor” bank account; transmission, signatures and nomination follow depository rules, so plan ownership carefully.

K

KYC. Know Your Client, the identity and related verification process required for regulated financial accounts. Keep PAN, address, mobile, email and other required details current to avoid service restrictions and fraud alerts going unnoticed.

L

Large cap. A relatively large listed company. Under the framework used for Indian mutual-fund categorisation, large caps are the first 100 companies by full market capitalisation; informal labels on market websites may use different cut-offs.
Leverage. Exposure larger than the investor’s own capital, created through borrowing or derivatives. It multiplies losses as readily as gains and can force an exit before a thesis has time to work.
Limit order. An order to buy no higher than a stated price or sell no lower than one. It controls the worst acceptable price but can remain unfilled, partly fill, or lose queue priority after modification.
Liquidity. How readily a security can be traded in meaningful quantity without moving its price substantially. Look beyond daily volume to spread, order-book depth and normal transaction size.
Listed company. A company whose specified securities are admitted to trading on a recognised stock exchange. Listing adds disclosure obligations; it is not a certificate of business quality or safety.
Listing gain or loss. The difference between an issue price and the market price when trading begins. It is a short-term market outcome, not evidence that the IPO was fairly valued.
Lower circuit. The lower permitted price limit for a security during a session when a price band applies. If sell orders pile up without buyers, the displayed lower-circuit price may not be an available exit.
Lot size. The quantity in which an order or contract must be placed. Cash-equity market lots and derivative contract lots follow different rules, and derivative lot sizes change over time.

M

Market capitalisation (market cap). Current share price multiplied by shares outstanding. A ₹50 share can represent a larger company than a ₹2,000 share; price per share alone does not measure cheapness.
Market order. An instruction to trade immediately against the best available orders. It prioritises execution, not price, which makes it risky in illiquid shares or fast markets.
Margin. Funds or eligible collateral required to support a leveraged or unsettled position. Margin is a risk buffer, not the maximum amount that can be lost.
Margin call. A demand to add funds or collateral when available margin falls below requirements. If it is not met, positions may be reduced or closed under the broker’s and clearing system’s rules.
Mid cap. A medium-sized listed company. For Indian mutual-fund categorisation, the label covers companies ranked 101st through 250th by full market capitalisation; casual screeners may classify them differently.
Moat. A durable competitive advantage that may protect returns, such as cost leadership, switching costs, distribution or regulation. “Strong brand” is not enough; look for evidence in margins, retention and reinvestment economics.
Multibagger. A share that rises to a multiple of its original price. The word describes a past or hoped-for outcome, not a discoverable security type; promoters of tips often use it to suppress discussion of downside.
Mutual fund. A pooled vehicle managed according to a stated scheme mandate. Investors own units of the scheme, not the underlying shares directly, and returns reflect portfolio performance after costs.

N

NAV. Net asset value: a fund’s assets minus liabilities, expressed per unit where applicable. An ETF can trade slightly above or below NAV; a lower mutual-fund NAV does not make one scheme cheaper than another.
Nifty 50. NSE’s flagship 50-stock, free-float-market-cap-weighted index. It is a large-company benchmark, not a complete picture of every listed Indian share.
Nomination. A facility to name person or persons who may claim securities after an account holder’s death, subject to applicable law and process. It supports transmission but should be coordinated with broader estate planning.
NSE. National Stock Exchange of India, a recognised stock exchange offering equity and other market segments. An NSE ticker identifies a listing venue; it does not identify the demat account where delivered shares are held.
NSDL. National Securities Depository Limited, one of India’s two securities depositories. Investors access NSDL services through registered Depository Participants.

O

Offer for Sale (OFS). A mechanism through which existing shareholders, often promoters, sell shares to the public through the exchange or as part of an issue. The selling shareholder receives the proceeds, not the company.
Open interest (OI). The number of derivative contracts remaining open, rather than the number traded during the day. Rising OI shows position creation but does not reveal a reliable bullish or bearish direction by itself.
Option. A derivative giving its buyer a right under specified terms while imposing an obligation on the seller if exercised or assigned. Option value is affected by price, strike, time, volatility and interest rates.
Order book. The queue of current buy and sell orders at different prices. It shows visible liquidity at that moment, not hidden orders, future demand or guaranteed execution.
Oversubscription. Demand for an issue exceeding the shares available in a category. It can reduce allotment probability; it does not guarantee a listing gain or strong post-listing performance.

P

P/B ratio. Price-to-book ratio: market price per share divided by book value per share, or market cap divided by equity. It is most useful when book assets and liabilities are economically meaningful and honestly stated.
P/E ratio. Price-to-earnings ratio: share price divided by EPS, using a clearly specified earnings period. A low P/E can reflect risk or peak cyclical profit; a high P/E can already price in years of growth.
Pledge. Use of shares as collateral while ownership remains subject to the pledge arrangement. High promoter pledging can amplify risk because a price fall may lead to more collateral demands or invocation.
Portfolio. The collection of investments owned by a person or institution. Portfolio-level exposure, correlation and position size matter even when every individual holding appears attractive.
Price discovery. The continuous process through which bids and asks establish traded prices. It can be noisy or distorted in thin markets; the latest price is an agreement between two parties, not an appraisal of intrinsic value.
Primary market. The market in which issuers raise capital by offering new securities. In the secondary market, investors generally trade existing securities with one another.
Promoter. A person or group identified with forming or controlling an Indian company under applicable disclosure rules. Promoter status is a legal and disclosure concept, not automatically a mark of good governance.
Promoter holding. The percentage of a company’s equity held by its promoter group. Track changes, encumbrances and reasons: high, low, rising and falling ownership can each mean different things.
Prospectus / Red Herring Prospectus (RHP). The regulated offer document describing an issue, business, financials, risks, use of proceeds and selling holders. Read risk factors and objects of the issue before relying on an IPO advertisement.
PSU. Public sector undertaking, commonly a company controlled by the central or a state government. Government ownership can affect policy, capital allocation and dividends, but PSUs are not one uniform investment category.
Put option. A contract giving the buyer the right, but not the obligation, to sell an underlying asset at a strike price under specified terms. The premium can expire worthless even if the investor’s broad concern was reasonable.

Q

QIB. Qualified Institutional Buyer, a defined category of sophisticated institutional applicants in securities issues. QIB demand is often reported in IPO coverage but should not replace independent valuation work.
Quarterly results. A company’s periodic financial results, normally including income statement, selected balance-sheet or cash-flow information and notes under applicable requirements. Compare year-on-year, sequential and full-year context before drawing a conclusion.

R

Record date. The date on which the company checks its shareholder records to identify entitlement for a corporate action. Because settlement matters, the ex-date is usually the more practical trading-calendar date for an investor.
Registrar and Transfer Agent (RTA). An intermediary that maintains investor and security records and processes services for an issuer or fund, including corporate actions and demat-related coordination.
REIT. Real Estate Investment Trust, a regulated pooled vehicle that owns or finances income-producing real-estate assets under its mandate. Listed units trade on exchange, but distributions, leverage, occupancy and interest rates affect value.
Retail Individual Investor (RII). An individual applicant falling within the retail category and application limits specified for an issue. Read the current offer document because thresholds and category rules can change.
Return on equity (ROE). Profit attributable to equity holders divided by average shareholders’ equity. High leverage or a very small equity base can inflate ROE, so use it with debt and cash-flow measures.
Return on capital employed (ROCE). Operating profit relative to capital used in the business, based on the analyst’s chosen definition. It helps assess capital efficiency, but financial companies require different measures.
Rights issue. An offer allowing eligible existing shareholders to buy new shares, usually in a stated ratio and price. Ignoring it can dilute ownership; participating still requires judging why the company needs capital.
Risk-reward ratio. A comparison between a planned loss and hoped-for gain, commonly used by traders. A 1:3 label is meaningless without realistic probabilities, slippage and a consistently followed exit rule.
Rolling returns. Returns calculated repeatedly over overlapping windows, such as every three-year period. They reveal consistency and entry-date dependence better than one convenient point-to-point return.

S

Secondary market. The market where investors buy and sell already-issued securities, usually through an exchange. The company normally receives no money when its existing shares change hands.
SEBI. Securities and Exchange Board of India, the securities-market regulator. Investors can use SEBI resources to check registrations, learn market processes and understand grievance routes.
Sensex. BSE’s flagship 30-stock, free-float-market-cap-weighted index. Like the Nifty 50, it can rise even when many smaller shares fall because large constituents carry more weight.
Share. A unit representing an ownership interest in a company. Ordinary equity shareholders have a residual claim: lenders and other prior claims are paid before equity in liquidation.
Shareholder. A person or entity that owns shares. Rights depend on the security and law and may include voting, dividends when declared, information and participation in corporate actions.
Shareholding pattern. A periodic disclosure showing ownership categories such as promoters, institutions and public shareholders. Compare periods and inspect pledging or concentration rather than treating one percentage as a verdict.
Short selling. Selling a security you do not own, expecting to buy it back lower. In India’s cash market, ordinary intraday shorts must be handled within settlement rules; delivery shorts generally require an approved borrowing mechanism.
Small cap. A smaller listed company. For Indian mutual-fund categorisation, small caps are companies ranked 251st onward by full market capitalisation; small size often brings lower liquidity and greater business risk.
SME IPO. A public issue on an exchange platform intended for eligible small and medium enterprises. Trading lots, liquidity, disclosure history and concentration can differ materially from main-board issues.
Stock split. Division of each share into more shares with a proportionately lower face value and theoretical price. A 1-to-5 split changes units, not the underlying business value by itself.
Stop-loss order. An order activated when a trigger price is reached, intended to limit loss or protect profit. The trigger is not a guaranteed execution price, especially during a gap or in a thin order book.
STT. Securities Transaction Tax, charged on specified securities transactions under current rules. Paying STT does not replace brokerage, exchange charges, GST, stamp duty or applicable income tax.
Surveillance measure (ASM/GSM). Additional exchange monitoring or trading conditions applied to securities meeting surveillance criteria. Inclusion is a risk signal and control measure, not by itself a finding of wrongdoing.
Swing trading. Holding a position for days or weeks to capture a price move. It sits between intraday trading and long-term investing and still needs a defined entry, exit, size and event-risk plan.

T

T+1 settlement. Settlement on the next working day after the trade date for the normal rolling cycle. NSE also documents an optional T+0 mechanism for eligible trades; weekends and relevant holidays are excluded from settlement-day counting.
Technical analysis. Study of price, volume and related indicators to form trading rules or market observations. A chart pattern is not a guaranteed forecast and must be tested with liquidity, costs and risk controls.
Tick size. The minimum permitted price increment for an order in a security or contract. It affects quoting, spreads and the exact prices at which a limit order can be entered.
Trade-to-trade segment. A surveillance-linked settlement category in which trades require delivery and intraday netting is restricted. Check the current exchange series and rules before placing an order.
Trading account. The broker account used to submit and manage exchange orders. It is distinct from the demat account that records delivered securities.
Trailing stop-loss. A stop level designed to move in a favourable direction as price moves, while not widening when price reverses. Broker implementation varies, and gaps can still produce a worse exit.
Turnover. The total value of transactions or, in company accounts, a term often used for revenue. Context matters: trading turnover used for tax reporting is not always simple purchase value plus sale value.

U

Underwriter. An intermediary that helps structure and distribute an issue and may assume obligations described in the underwriting agreement. Its involvement does not eliminate business or pricing risk for investors.
Upper circuit. The upper permitted price limit for a security during a session when a price band applies. A queue of buyers at that price is not proof they can buy, nor that the same demand will exist after the band resets.

V

Valuation. The process of estimating what an asset is worth using cash flows, earnings, assets, comparable businesses or other methods. A good company and a good share purchase are different questions because price matters.
Volatility. The degree of price variation over time. Historical volatility describes what happened; implied volatility reflects option-market pricing. Neither is the same as permanent loss of capital, though both affect risk.
Volume. The number of shares or contracts traded during a period. High volume confirms participation, not direction: heavy buying and heavy selling are two sides of the same completed trades.
VWAP. Volume-weighted average price, calculated from traded prices weighted by volume over a chosen session or period. Traders use it as an execution reference; it is not intrinsic value.

W

Warrant. A security giving a right to acquire shares under specified terms, often after payment of additional money. Exercise price, expiry, dilution and promoter allotment terms all require scrutiny.
Watchlist. A saved set of securities to monitor. A useful watchlist records the reason, valuation range and disconfirming evidence; a list of rising tickers can quietly become a list of impulse purchases.
Working capital. Current assets minus current liabilities, with analytical variations. Rising receivables or inventory can consume cash even while reported profit grows; negative working capital can be efficient or dangerous depending on the business.

X

XIRR. Extended internal rate of return, an annualised return calculation for cash flows occurring on irregular dates. It is useful for SIPs and portfolios with additions or withdrawals, but depends on complete, correctly signed cash flows.

Y

Yield. Income received relative to price or value, such as dividend yield on a share or yield to maturity on a bond. Always identify which income, period and denominator a quoted yield uses.
Yield trap. A security that appears attractive because its trailing yield is high, while the price has fallen or the distribution may be unsustainable. Test earnings, cash flow, debt and payout history before trusting the percentage.

Z

Zero-coupon bond. A bond that does not make periodic coupon payments and is generally issued or traded at a discount to the amount repaid at maturity. Its market value can still move with interest rates and credit risk.

Ten distinctions that prevent expensive mistakes

Many beginner errors come from confusing two related terms rather than not knowing either one.

Do not confuse	The practical difference
Share price and market cap	Price is for one unit; market cap values all outstanding equity
Demat account and trading account	One records securities; the other submits orders
Market order and limit order	One prioritises execution; the other protects a price boundary
Dividend yield and total return	Yield counts distributions relative to price; total return also includes price change
Volume and open interest	Volume counts contracts traded during a period; OI counts derivative contracts still open
Bonus issue and stock split	Both increase units and adjust price, but the legal/accounting mechanisms differ
Record date and ex-date	Record date identifies holders in company records; ex-date is the key market-trading cut-off
Profit and cash flow	Profit follows accounting recognition; cash flow records cash moving in and out
Price band and market-wide circuit breaker	One constrains an individual security; the other halts broad markets after index moves
Investing and trading	Investing centres on business value over years; trading centres on price behaviour and a defined time horizon

Questions to ask when a market number looks exciting

Number or headline	Ask this first	Common trap
“P/E is only 8”	Are current earnings normal and supported by cash?	Buying a cyclical peak or a company with hidden risk
“Dividend yield is 9%”	Was the last dividend recurring and affordable?	Extrapolating a one-off distribution
“Stock hit upper circuit”	Could buyers actually get filled, and what changed fundamentally?	Treating an order queue as guaranteed future demand
“Volume is 10 times normal”	Was the move linked to a filing, block trade or speculation?	Assuming high volume is automatically bullish
“Promoter owns 70%”	Is any holding pledged, and how are minorities treated?	Equating concentrated control with governance quality
“IPO is 50 times subscribed”	Which category bid, at what valuation, and how much is OFS?	Confusing application demand with durable value
“Near its 52-week low”	Did business value fall too?	Treating an old price anchor as intrinsic value

How to use these terms when researching a stock

A glossary becomes useful only when it improves behaviour. Use this sequence before acting on a stock idea:

Identify the instrument. Is it an equity share, ETF, REIT, warrant, future or option? Similar tickers can carry completely different rights and risks.
Check the venue and liquidity. Confirm NSE or BSE symbol, ISIN, volume, spread, price band and surveillance series on the exchange.
Understand the business. Read the annual report, quarterly results, shareholding pattern and material announcements.
Check financial quality. Reconcile earnings with operating cash flow, then study debt, dilution, ROE or ROCE in the right industry context.
Judge valuation. Compare market cap, P/E or P/B with business economics, history and realistic assumptions—not merely with a favourite peer.
Plan the order. Decide quantity and use an appropriate limit or market order. Include spread, charges, taxes and the possibility of a partial fill.
Define the risk. Know what evidence would disprove the thesis, how much capital is exposed and whether you can exit under poor liquidity.

FAQ

What is stock market terminology?

Stock market terminology is the vocabulary used to describe securities, exchanges, accounts, orders, financial performance, valuation, corporate actions and risk. In India it also includes market-specific terms such as SEBI, NSE, BSE, demat, DP, ASBA, ISIN and T+1 settlement.

Which stock market terms should a beginner learn first?

Start with share, market capitalisation, NSE, BSE, SEBI, demat account, trading account, bid, ask, market order, limit order, volume, P/E, dividend and volatility. Those terms are enough to understand a basic quote screen and avoid confusing share price with business value.

In everyday Indian usage, “share market” and “stock market” usually describe the same broad marketplace, so most share market terminology overlaps. Technically, a share is one ownership unit in a company, while “stock” can be used more broadly or collectively.

What is the difference between NSE and BSE?

They are separate recognised stock exchanges with their own systems and benchmark indices: Nifty 50 for NSE and Sensex for BSE. Many large companies trade on both. Check liquidity and the exact symbol before ordering; a listing on either exchange does not change the underlying ownership claim.

Is a demat account the same as a trading account?

No. A demat account records securities in electronic form through a Depository Participant connected to NSDL or CDSL. A trading account, operated through a broker, is used to place orders on an exchange. Brokers often open both in one onboarding process, which is why the distinction is easy to miss.

Does an upper circuit mean a stock will rise again tomorrow?

No. It means the stock reached its permitted upper price limit for that session. There may be no sellers, so queued buyers might not receive shares. The next session can bring a different price band, new information, sell orders or a reversal.

Does a low P/E mean a stock is cheap?

Not necessarily. The market may be pricing weak growth, governance risk, high debt or unsustainable cyclical earnings. Compare the ratio with normalised profits, cash flow, peers and the company’s own history. Gale’s P/E ratio guide explains the calculation and its traps.

Where should I verify Indian stock market definitions?

Use official SEBI investor material for regulatory and investor concepts; NSE and BSE for trading, settlement, security and corporate-announcement details; and NSDL or CDSL for demat terminology. Broker help pages are useful for broker-specific features such as GTT orders, but their implementation may not be universal.
