52-Week Low(One-Year Low)
A 52-week low is the lowest price at which a stock or index has traded over the preceding 52-week period, commonly used as a technical support reference and a signal of potential distress or deep value.
Absolute Return(Total Return)

Advance-Decline Ratio(ADR)
The Advance-Decline Ratio is a market breadth indicator that compares the number of stocks that closed higher on a given day to the number that closed lower, providing a snapshot of the overall direction of market participation.
After-Hours Trading(extended hours trading)
After-hours trading refers to the buying and selling of securities outside the standard exchange trading window. In India, the concept has very limited applicability compared to US markets because NSE and BSE do not operate continuous after-hours sessions for equity shares.
After-Market Order(AMO)
An after-market order (AMO) is an order placed by investors outside regular trading hours — typically after the market closes — that is queued and submitted to the exchange when trading next opens.
All-Time High(ATH)
An all-time high is the highest price level ever recorded for a stock, index, or other financial instrument since it began trading, representing the peak of historical market valuation.
Alpha(Jensen's Alpha)
Alpha is the excess return generated by a stock or portfolio above its expected return (based on its beta and the market's return), representing the value added by skill, selection, or timing rather than simply riding market movements. Positive alpha indicates outperformance; negative alpha indicates underperformance.
Analyst Consensus(street estimates)
Analyst consensus refers to the mean or median of earnings per share (EPS), revenue, and key financial metric estimates published by multiple sell-side research analysts covering a specific stock, aggregated by data providers such as Bloomberg, Thomson Reuters (now Refinitiv/LSEG), and domestic platforms, and used as the benchmark against which actual reported results are measured.
Annualised Return(CAGR)
Annualised return converts an investment's total return over any period into an equivalent annual rate, enabling fair comparison across investments held for different durations. In India, mutual fund performance disclosures use annualised returns (CAGR) for periods exceeding one year.

Bear Market(Bear Run)
A bear market is a sustained decline of 20% or more in stock prices from recent highs, typically accompanied by negative investor sentiment, rising risk aversion, and deteriorating economic fundamentals. India's markets entered bear phases during the 2008 global financial crisis and the COVID-19 outbreak in early 2020.
Benchmark Index(Market Benchmark)
A benchmark index is a standard market index used as a reference point to evaluate the performance of a stock, portfolio, or fund relative to the broader market.
Beta(Beta Coefficient)
Beta is a measure of a stock's price volatility relative to a benchmark index (typically Nifty 50 in India), indicating how much the stock tends to move for a given move in the market. A beta greater than 1 signals higher volatility than the market; less than 1 signals lower volatility.

Consolidation(Sideways Market)
Consolidation in stock markets refers to a period where prices trade within a relatively narrow range after a significant move up or down, reflecting a balance between buyers and sellers as the market digests recent information. It is a pause rather than a directional trend.
Continuous Trading Session(regular trading session)
The Continuous Trading Session is the main trading period on NSE and BSE, running from 9:15 am to 3:30 pm on weekdays, during which buy and sell orders are matched automatically and immediately as they arrive in the order book using price-time priority rules.

The COVID-19 market crash of March 2020 caused the Nifty 50 to fall nearly 38 percent from its February high to its March low in just 33 trading sessions, triggering multiple market-wide circuit breakers, followed by one of the fastest and strongest recoveries in global equity market history.
Cyclical Stock(Cyclical Sector Stock)
A cyclical stock is a share in a company whose revenues, earnings, and stock price tend to move in line with the broader economic cycle — rising strongly during economic expansions and contracting during recessions or slowdowns.
Defensive Stock(Non-Cyclical Stock)
A defensive stock is a share in a company whose business generates relatively stable revenues and earnings regardless of the broader economic cycle, making its stock price less sensitive to recessions, slowdowns, or general market downturns.
Demat Account(Dematerialised Account)
A demat (dematerialised) account is an electronic repository that holds an investor's financial securities — shares, bonds, ETFs, and mutual fund units — in digital form, eliminating the need for physical certificates. In India, demat accounts are maintained by NSDL and CDSL through SEBI-registered Depository Participants.
Demat Account Statistics (India)
India's demat account base exploded from ~4 crore in March 2019 to over 18 crore by 2024 — a 4.5x surge driven by pandemic-era digital adoption, discount brokers, zero-cost account opening, and India's equity market rally — with CDSL holding over 75% market share by active demat accounts.
Dematerialisation Drive 1996(Demat History India)
India's dematerialisation initiative, anchored by the formation of NSDL in 1996 and CDSL in 1999, converted physical share certificates into electronic form held in demat accounts, eliminating the fraud risks and settlement failures endemic to the paper-based system and enabling T+2 and subsequently T+1 settlement.

Earnings season refers to the concentrated period — roughly four to six weeks following the end of each financial quarter — during which publicly listed Indian companies announce their quarterly financial results, triggering heightened analyst activity, institutional repositioning, and elevated market volatility.
Earnings Surprise(earnings beat)
An earnings surprise occurs when a company's reported quarterly or annual earnings per share (EPS) or net profit deviates materially from the consensus estimate published by analysts before the result announcement, and the direction and magnitude of the surprise typically drives an immediate and sometimes sharp stock price reaction.
Election Year Market Performance (India)
Election Year Market Performance refers to the historical pattern of Indian equity market behaviour during Lok Sabha general election years, characterised by pre-election optimism, volatility during result counting, and post-election directional moves aligned with the market's assessment of policy continuity or change.
Equal-Weight Index(equal-weighted index)
An equal-weight index assigns identical portfolio weights to each constituent stock regardless of market capitalisation, contrasting with traditional market-cap-weighted indices where larger companies automatically receive higher weights.

Equity represents the ownership interest held by shareholders in a company after all liabilities have been subtracted from assets. In the Indian capital markets, equity shares are the most widely traded instruments on the NSE and BSE.
Face Value(Par Value)
Face value (also called par value) is the nominal value of a share as stated in the company's memorandum of association, typically Rs 1, Rs 2, Rs 5, or Rs 10 per share in India. It is the base value used for calculating dividend per share and is distinct from the market price.
Factor-Weighted Index(smart beta index)
A factor-weighted index assigns constituent weights based on specific fundamental or statistical characteristics — such as momentum, quality, low volatility, or value — rather than market capitalisation, forming the basis of smart beta index strategies; NSE India operates a range of factor indices under the Nifty Factor Index series.
Fear and Greed Index (Concept)(Fear Greed Gauge)
The Fear and Greed Index is a composite sentiment gauge — popularised globally by CNN Business — that aggregates multiple market-derived signals to produce a single score indicating whether investors are behaving in a fearful or greedy manner; Indian market practitioners and data vendors have developed analogous composite indicators adapted to NSE and BSE data.

Foreign Portfolio Investor (FPI) Categories(FPI categories)
Under SEBI's Foreign Portfolio Investors Regulations, 2019, FPIs are classified into Category I and Category II based on risk profile and regulatory oversight, replacing the earlier three-tier structure and streamlining the registration process to attract more foreign capital into Indian capital markets.
Fractional Shares(fractional investing)
Fractional shares allow investors to purchase a portion of one full share — for example, 0.5 shares of a company — enabling participation in high-priced stocks with small amounts of capital; this facility is currently unavailable in India under the existing regulatory framework, though alternatives like mutual funds and ETFs serve a similar purpose.
Free Float(Free-Float)
Free float refers to the proportion of a company's total shares that are available for trading in the open market, excluding shares held by promoters, governments, and strategic investors. Indian indices like the Nifty 50 and Sensex use free-float market capitalisation for index weighting.
Free Float Adjustment Factor(IWF)
The Free Float Adjustment Factor (FFAF) or Investible Weight Factor (IWF) is the fraction of a company's total shares that is available for trading by public investors, used by index providers to weight each constituent proportionally by its freely tradeable market capitalisation rather than its total market capitalisation.
Free Float Methodology(free float market cap)
Free float methodology is the approach used by index providers to construct market capitalisation-weighted indices by counting only the shares that are freely available for trading in the market—excluding locked-in promoter holdings, government stakes, strategic cross-holdings, and other restricted shares—rather than the total shares outstanding.

In SEBI's IPO framework, a High Net Worth Individual (HNI) — formally termed a Non-Institutional Investor (NII) — is an individual or entity (other than QIBs or retail investors) applying for securities worth more than ₹2 lakh in a public offer; beyond IPOs, HNIs typically hold investable assets above ₹5 crore and may access PMS, AIFs, and structured products.
How Indian Capital Markets Work
Indian capital markets function through an interconnected chain of regulators (SEBI, RBI), exchanges (NSE, BSE), depositories (NSDL, CDSL), clearing corporations, and intermediaries (brokers, DPs, custodians), all working together to facilitate issuance, trading, and settlement of securities.
How to Start Investing (Roadmap)(investing guide for beginners)

Institutional Trading(block deal window)
Institutional trading refers to the buying and selling of securities in large quantities by entities such as mutual funds, insurance companies, pension funds, banks, and foreign portfolio investors; Indian exchanges facilitate this through dedicated block window sessions that allow large trades to be executed with minimal market impact.
Interoperability (Clearing Corporations)(clearing interoperability)
Interoperability between clearing corporations allows a market participant to execute a trade on one stock exchange and have it cleared and settled by the clearing corporation of a different exchange, enabling margin netting across platforms and promoting competition among clearing entities.
Intraday Square-Off(auto square-off)
An intraday square-off is the compulsory closing of all open intraday positions by the broker's Risk Management System (RMS) before the end of the trading day, ensuring that no delivery obligation arises from a position that was opened with intraday (MIS/BO/CO) margin and not converted to delivery.

January Effect
The January Effect is a historically observed seasonal pattern in global equity markets where stock prices — particularly smaller-capitalisation stocks — tended to rise in January, attributed to year-end tax-loss selling followed by reinvestment and institutional portfolio repositioning at the start of a new calendar year.
Ketan Parekh Scam 2001(K-10 Scam)
The Ketan Parekh scam of 2001 involved the artificial inflation of a concentrated group of technology and media stocks known as the K-10, funded through pay orders and co-operative bank loans, ultimately triggering a market crash and fresh regulatory overhaul.

Lower Circuit(Lower Limit)
A lower circuit is the minimum price limit a stock can fall to in a single trading session, set as a fixed percentage below the previous day's closing price by SEBI and exchanges. Once triggered, no trade can occur below this price for the remainder of the session.
Margin Interest(MTF interest)
Margin interest is the fee charged by a broker to a client for the use of borrowed funds or for carrying positions that exceed the client's own capital, typically levied as a percentage per annum on the funded or leveraged portion, and applicable both in the Margin Trading Facility (MTF) for delivery trades and for overnight funding of leveraged positions.

Market Capitalisation Weighted Index(cap-weighted index)
A market capitalisation weighted index assigns each constituent stock a weight proportional to its market capitalisation (or free-float market capitalisation), so that larger companies have a greater influence on index movement; the Nifty 50, Sensex, and most major Indian indices use a free-float market cap weighting methodology.
Market Cycle Phases
Market Cycle Phases refers to the four broadly recognised stages — accumulation, markup, distribution, and markdown — through which equity prices historically moved in a repeating pattern, reflecting the sequential involvement of informed institutional capital, the general public, smart-money exit, and broad decline.
