Most “A to Z” guides promise more than they deliver — a list of buzzwords with no real explanation attached. This one is built differently: every term below gets an actual, plain-language explanation, in the order the alphabet puts them, so you can read start to finish or jump straight to the one word that’s been confusing you. A couple of letters (J, mainly) don’t have a natural share market term, so we’ve skipped them rather than force one in. A free, downloadable PDF of this entire glossary is linked at the end if you’d rather save a copy than bookmark a webpage — though this page itself will always be the more current version, since it gets updated the moment a rule or term changes. share market a to z pdf free download link here
The Complete Glossary
A — ASM (Additional Surveillance Measure)
When a stock shows unusual price or volume swings, exchanges can place it under ASM, adding extra margin requirements and trading restrictions until things settle down. Landing on this list is a caution flag on recent trading behavior, not necessarily a verdict on the company itself.
B — Bull Market & Bear Market
A bull market describes a sustained stretch of rising prices and rising confidence; a bear market is the mirror image, a sustained decline. Neither moves in a straight line, and neither lasts forever.
C — Circuit Breaker
An automatic, exchange-wide trading halt triggered when the market — or a single stock — moves beyond a set percentage in either direction. It’s a built-in pause designed to stop panic from feeding on itself.
D — Demat Account
The electronic account that holds your shares, replacing the paper certificates investors used decades ago. Most accounts today open as a Basic Services Demat Account by default if holdings stay under the current threshold, which keeps annual charges minimal. Our full guide to opening one covers the current process and rules.
E — Equity
Another word for a share: a unit of ownership in a company. “Equity market” and “stock market” get used interchangeably in almost every everyday conversation about investing.
F — F&O (Futures & Options)
Derivative contracts whose value is based on an underlying stock or index, used for hedging existing positions or for pure speculation. F&O carries meaningfully higher risk than buying shares outright, which is exactly why regulators have tightened eligibility and margin requirements around it in recent years.
G — GTT Order (Good Till Triggered)
An order that stays live until a price you set is actually hit, rather than expiring at the end of the trading day — useful for setting a target sale or a stop-loss without watching a screen all day.
H — Holding Period
The length of time you own a stock before selling it, which directly determines whether any gain gets taxed as short-term or long-term capital gains.
I — IPO (Initial Public Offering)
The first time a company sells shares to the public, moving from private ownership into a publicly listed, publicly tradable one.
K — KYC (Know Your Customer)
The identity verification process — PAN, address proof, a photograph — every broker must legally complete before opening your account. It’s a one-time process, not something you repeat with every trade.
L — LTCG (Long-Term Capital Gains)
The tax treatment applied to profit from shares held longer than a set period, generally taxed more favorably than short-term gains to reward patience over quick flipping.
M — MTF (Margin Trading Facility)
A facility that lets you buy shares using funds borrowed from your broker, putting up only a portion of the purchase price yourself. It amplifies both gains and losses equally, which makes it worth understanding thoroughly before using — our full MTF guide covers the mechanics in depth.
N — NSE (National Stock Exchange)
One of India’s two major exchanges, alongside the BSE, where the actual buying and selling of listed shares takes place. NSE’s own site publishes live data and company filings directly.
O — Open Interest
The total number of outstanding derivative contracts that haven’t yet been settled or closed — a measure of how much money is actively committed to a position, not which direction it’s betting. Our guide to reading open interest breaks this down further.
P — P/E Ratio (Price-to-Earnings)
A company’s share price divided by its earnings per share — a quick, rough way to gauge whether a stock is priced cheaply or expensively relative to how much profit it’s actually generating.
Q — Quarterly Results
The financial performance a listed company must disclose every three months, covering revenue, profit, and management commentary — one of the biggest, most predictable sources of short-term price movement on the calendar.
R — Resistance Level
A price point where a stock has historically struggled to rise past, as selling pressure tends to increase near that level. It’s a pattern observed in past price action, not a guaranteed ceiling going forward.
S — SEBI (Securities and Exchange Board of India)
The regulator overseeing India’s securities markets, enforcing disclosure rules, broker conduct, and investor protection so the whole system stays trustworthy enough for ordinary people to use.
T — T+1 Settlement
The current standard timeline for when shares and funds actually change hands after a trade — one trading day after the transaction, faster than the T+2 and T+3 cycles India used in earlier years.
U — Upper Circuit & Lower Circuit
The maximum percentage a stock, or the market as a whole, is allowed to move in a single session before trading automatically pauses — upper for a sharp rise, lower for a sharp fall.
V — Volatility
How much and how quickly a stock’s price swings, in either direction. Higher volatility means bigger potential gains and bigger potential losses in the same breath — it’s a measure of movement, not of quality.
W — Watchlist
A saved list of stocks you’re tracking without necessarily owning yet. Most trading apps let you build one, so you’re not searching for the same tickers every single day.
X — XIRR (Extended Internal Rate of Return)
The return calculation used for investments made at irregular intervals, like SIPs, since a simple percentage return doesn’t account for money going in at different times and earning returns for different lengths of time.
Y — Yield
The income, typically dividends, a stock generates relative to its price, usually expressed as a percentage — a way to compare income-generating potential across different stocks regardless of their actual share price.
Z — Zero Coupon Bond
A bond that doesn’t pay periodic interest at all. Instead, it’s sold at a discount to its face value, and the entire return comes from the gap between what you paid and what you receive at maturity.
A glossary won’t make you a better investor by itself. But not knowing these words will quietly make every article, every app screen, and every broker conversation harder than it needs to be.

Frequently Asked Questions
Is this glossary specific to the Indian stock market?
Yes — terms like ASM, GSM, MTF, and the settlement cycle are specific to how NSE and BSE operate, though core concepts like P/E ratio and volatility apply to any stock market globally.
Do I need to memorize all of these before I start investing?
No. Most investors learn these gradually, encountering each term in context as it becomes relevant, rather than studying the whole list upfront. Bookmarking this page — or saving the free PDF — to check back against is far more realistic than memorizing it in one sitting.
Will this glossary be updated as terms or rules change?
Yes — definitions tied to specific regulations, like settlement cycles or margin rules, get revisited whenever SEBI updates them, so this on-page version will always reflect the current rules, even in the months after you’ve already downloaded the PDF.
