Indian Stock Market Overview
The Indian stock market is a multi-exchange, multi-asset ecosystem regulated by SEBI, comprising over 5,000 listed companies across BSE and NSE, with combined market capitalisation exceeding ₹300 lakh crore, making it one of the largest and fastest-growing equity markets in the world.
India's stock market traces its origins to 1875 when the Bombay Stock Exchange (BSE) was founded under a banyan tree in Dalal Street — the oldest stock exchange in Asia. Over 150 years later, it has evolved into a sophisticated two-exchange system anchored by BSE and the National Stock Exchange (NSE), which was established in 1992 and quickly became the world's largest derivatives exchange by contract volume.
The two flagship indices — Sensex (BSE, 30 stocks) and Nifty 50 (NSE, 50 stocks) — serve as the barometers of Indian economic sentiment. Beyond these, sectoral indices such as Nifty Bank, Nifty IT, Nifty Pharma, Nifty FMCG and Nifty Midcap 150 allow investors to track specific segments of the economy.
The market structure rests on three pillars: the primary market (IPOs, FPOs, rights issues), the secondary market (exchange-traded buying and selling), and the derivatives market (futures and options on stocks and indices). The clearing and settlement infrastructure is handled by NSE Clearing Limited and Indian Clearing Corporation Limited (ICCL), both of which are SEBI-registered clearing corporations.
SETTLEMENT: India moved to T+1 rolling settlement in 2023, making it one of the few major markets globally to achieve next-day settlement. This improvement has reduced counterparty risk and freed up capital more quickly for investors.
DEMAT INFRASTRUCTURE: Shares in India are held in electronic (dematerialised) form through two depositories — NSDL and CDSL — and accessed via Depository Participant (DP) accounts, commonly called demat accounts. As of 2024, India had over 18 crore demat accounts, up from just 4 crore in 2019.
INVESTOR BASE: The investor base includes domestic retail investors, domestic institutional investors (DIIs — mutual funds, insurance companies, pension funds), and foreign portfolio investors (FPIs). The growing SIP culture has made domestic flows a powerful stabilising force, often absorbing FPI selling in volatile periods.
The Indian market has delivered impressive long-term returns — the Nifty 50 has compounded at approximately 12-13% CAGR since inception — making it one of the best-performing large equity markets over the past three decades. The ecosystem continues to deepen with new instruments (REITs, InvITs, SME IPOs, social stock exchanges) and improving regulatory standards.
