How the Indian stock market actually works
The exchanges, the regulator, the depositories, the settlement cycle and the derivative segment. Ten concepts covering the machinery, not the strategy.
The machinery, before the strategy
Most people learn what to buy long before they learn what happens when they press the button, which is why a rejected order, a settlement holiday or a circuit limit comes as a surprise. This page covers the machinery: who runs the market, who guarantees the trade, where the shares are actually kept, and what the rules do when things move too fast.
The structure is layered. SEBI regulates. The exchanges, NSE and BSE, match orders. Clearing corporations guarantee settlement so that you are not exposed to the person on the other side of your trade. The depositories, NSDL and CDSL, hold the shares electronically, and your broker is a participant rather than a custodian. Each layer exists because of a specific failure the market experienced before it was built.
The derivative segment sits on top of all this, and it is where the largest share of Indian market turnover now happens. It is also where most retail losses happen, which is a reason to understand the mechanics before taking a position rather than after.
The ten concepts, and why each layer exists
Institutions first, then process, then the derivative segment that sits on top of both.
SEBI Regulations
The statutory regulator for securities markets. It licenses intermediaries, sets disclosure rules and enforces them, and most retail protections you rely on originate here.
NSE and BSE Basics
The two main exchanges. They match buy and sell orders anonymously and publish prices. They do not hold your shares and are not your counterparty.
Market Participants
Retail investors, domestic and foreign institutions, proprietary desks, market makers and arbitrageurs. Their different objectives are why liquidity exists at all.
Depository System
NSDL and CDSL hold shares in electronic form. Your demat account sits with a depository participant, which is why a broker failure does not by itself put your holdings at risk.
IPO Process
How a company lists: the offer document, the price band, book building, allotment and listing. The mechanics explain why oversubscription changes what you actually receive.
Trading and Settlement
The cycle from order to delivery. India settles on a compressed timetable, so the gap between trade and credit is now days rather than the weeks it once was.
Market Indices
Nifty and Sensex are weighted samples, not the market. Knowing the weighting method explains why an index can rise while most of its constituents fall.
Circuit Breakers and Market Halts
Rules that pause trading after a defined move. They exist to interrupt disorderly price discovery, and they can leave you unable to exit at the moment you most want to.
Futures Trading
An obligation to transact at a set price on a future date. Leverage cuts in both directions and margin is called daily, not at expiry.
Options Trading
A right rather than an obligation, priced by time and volatility as much as by direction. The most misunderstood instrument available to retail investors in India.
