India has three major exchanges. Most retail investors have heard of all three, but few can explain what makes them different — or why it matters which one a stock is listed on.
Here's the complete picture.
According to BSE India, the Bombay Stock Exchange is Asia's oldest stock exchange, established in 1875, and currently lists over 5,500 companies — more than any other exchange in Asia.
The Quick Answer
| Exchange | Full Name | What It Trades | Key Index |
|---|---|---|---|
| BSE | Bombay Stock Exchange | Stocks, bonds, mutual funds, derivatives | Sensex (30 companies) |
| NSE | National Stock Exchange | Stocks, derivatives, currency futures | Nifty 50 (50 companies) |
| MCX | Multi Commodity Exchange | Gold, silver, crude oil, copper, agri-commodities | iCOMDEX |
If you invest in stocks — shares of companies like TCS, HDFC Bank, or Reliance — you're using BSE or NSE (most likely both simultaneously). If you trade gold, crude oil, or agricultural futures, you're using MCX.
BSE — Bombay Stock Exchange
Established: 1875 Location: Dalal Street, Mumbai Listed companies: 5,500+ (largest number of listed companies in Asia) Key index: Sensex (S&P BSE Sensex) — tracks the top 30 companies by market capitalisation and liquidity
BSE is the oldest stock exchange in Asia. When it was founded in 1875, traders would gather under a banyan tree on Dalal Street. It has evolved from that into a fully electronic exchange, but the address hasn't changed.
What BSE is known for:
- Broader listing base — more small-cap and mid-cap companies list on BSE than NSE
- BSE SME platform — a dedicated segment for small and medium enterprises to list publicly
- Sensex — the most widely quoted index in Indian financial media
The Sensex: The Sensex (Sensitive Index) tracks 30 large, well-established, financially stable companies across key sectors. Companies are selected based on market capitalisation, trading frequency, and sector representation. When news headlines say "Sensex fell 500 points today," they're measuring the weighted movement of these 30 stocks.
Current weight leaders in Sensex include Reliance Industries, HDFC Bank, Infosys, ICICI Bank, and TCS — their moves dominate the index.
NSE — National Stock Exchange
Established: 1992 Location: Bandra Kurla Complex (BKC), Mumbai Listed companies: 2,000+ Key index: Nifty 50 — tracks the top 50 companies by free-float market capitalisation
NSE is the newer exchange but the higher-volume one. More trades happen on NSE than BSE on most trading days. NSE pioneered electronic trading in India — before NSE, BSE used an open-outcry system where traders shouted orders. NSE introduced screen-based trading in 1994, which transformed Indian markets.
What NSE is known for:
- Higher liquidity — more buyers and sellers at any given time
- Dominant in derivatives (F&O) — Nifty futures and Bank Nifty futures are among the world's most actively traded derivatives contracts
- Currency derivatives — USD/INR, EUR/INR futures and options
- Technology infrastructure — widely regarded as one of the most technically advanced exchange systems globally
The Nifty 50: The Nifty 50 (or just "Nifty") tracks 50 large-cap companies across 13 sectors. It is the benchmark most institutional investors, mutual funds, and portfolio managers use to measure performance. "The market is up 1.2% today" almost always refers to Nifty 50.
Bank Nifty: A sub-index of the 12 most liquid banking stocks. Extremely actively traded in the derivatives segment — Bank Nifty options are one of the highest-volume contracts in the world on any given day.
BSE vs NSE — Are They Different for Stock Investors?
For most retail investors buying shares, BSE and NSE are functionally equivalent. The same stocks (Reliance, TCS, HDFC Bank) are listed on both exchanges, and prices are nearly identical at any given moment due to arbitrage.
When you place a buy order for TCS through your broker, they route it to whichever exchange offers the better price — usually NSE for large-caps due to higher liquidity.
When the difference matters:
| Situation | Which Exchange Matters |
|---|---|
| Trading large-cap stocks | NSE (better liquidity, tighter spreads) |
| Investing in small/micro-cap companies | Check if listed on BSE SME or NSE Emerge |
| Trading F&O (Nifty, Bank Nifty) | NSE (dominant derivatives market) |
| Benchmarking your portfolio | Nifty 50 (NSE) is the standard benchmark |
| Following news headlines | Sensex (BSE) appears most in mainstream media |
The practical rule: Your broker handles the routing automatically. You rarely need to choose. The exchange becomes relevant when researching smaller companies that may only be listed on one of the two.
MCX — Multi Commodity Exchange
Established: 2003 Regulated by: SEBI (Securities and Exchange Board of India) — since 2015 What it trades: Commodities — metals, energy, agricultural products Key index: iCOMDEX (composite commodity index)
MCX is fundamentally different from BSE and NSE. It does not trade stocks (equity). It trades commodity futures and options — contracts to buy or sell a physical commodity at a future date and price.
What is traded on MCX:
| Category | Commodities |
|---|---|
| Precious metals | Gold, Silver, Gold Mini, Silver Mini |
| Base metals | Copper, Zinc, Lead, Aluminium, Nickel |
| Energy | Crude oil, Natural gas |
| Agricultural | Cardamom, Cotton, Crude palm oil, Castor seed |
Why gold on MCX, not NSE/BSE? Gold as a physical commodity trades on MCX as a futures contract. Gold ETFs (exchange-traded funds backed by physical gold) do trade on NSE and BSE — but these are investment instruments, not the commodity itself.
MCX trading hours: MCX follows a split-session structure. For non-agricultural commodities like gold, silver, and crude oil:
- Morning session: 9:00 AM – 5:00 PM
- Evening session (international commodities): 5:00 PM – 11:30 PM
The evening extension exists because gold and crude oil prices are heavily influenced by US markets — COMEX gold and NYMEX crude oil — which become active during India's evening hours. MCX must remain open to reflect real-time global price movements.
Who uses MCX:
- Commodity traders (gold, crude oil speculators)
- Jewellers and manufacturers hedging against gold/silver price risk
- Oil and gas companies hedging crude oil exposure
- Agricultural businesses hedging crop price risk
What MCX is NOT for: MCX does not trade company stocks. If you want to invest in a gold mining company, you'd buy those shares on NSE or BSE. If you want direct exposure to gold's price, you'd trade on MCX (or buy a gold ETF on NSE/BSE).
How They Are Regulated
All three exchanges are regulated by SEBI (Securities and Exchange Board of India):
| Exchange | Regulator |
|---|---|
| BSE | SEBI |
| NSE | SEBI |
| MCX | SEBI (transferred from FMC in 2015) |
Before 2015, MCX was regulated by the Forward Markets Commission (FMC), a separate regulator. In 2015, FMC was merged into SEBI, bringing all exchanges under one roof. This is why you may see old references to "SEBI-FMC merger" in financial history.
Sensex vs Nifty — Which Should You Track?
Both indices measure broadly the same thing — the performance of India's largest listed companies. They move together most of the time because they share the same large-cap stocks.
| Sensex | Nifty 50 | |
|---|---|---|
| Exchange | BSE | NSE |
| Companies | 30 | 50 |
| Base year | 1978-79 | 1995 |
| Broader representation | Less | More (50 companies) |
| Used by institutions | Less common | Standard benchmark |
| Media coverage | Dominant in TV/print | Dominant in financial analysis |
The practical guidance: Follow Nifty 50 if you are managing a portfolio or comparing fund returns. Follow Sensex if you are reading news and want the most commonly quoted number. They tell the same story.
What About Investors Who Want to Do Both?
Some investors want exposure to both equities (stocks on NSE/BSE) and commodities (on MCX). These are separate segments requiring separate accounts with your broker. Most full-service brokers offer both — your equity demat account handles NSE/BSE stocks, and a separate commodity account handles MCX futures.
The analysis for both is fundamentally different. Equity investing requires analysing company fundamentals — revenue, margins, management quality, competitive position. Commodity trading requires understanding supply-demand dynamics, global pricing, currency movements, and seasonal factors.

Frequently Asked Questions
What is the difference between BSE and NSE?
BSE (Bombay Stock Exchange, est. 1875) has over 5,500 listed companies and is tracked by the Sensex (30 companies). NSE (National Stock Exchange, est. 1992) lists 2,000+ companies and is tracked by the Nifty 50. NSE has higher trading volumes and dominates the derivatives market. For most retail investors buying large-cap stocks, prices are effectively identical on both exchanges.
What does MCX trade?
MCX (Multi Commodity Exchange) trades commodity futures and options — gold, silver, crude oil, natural gas, copper, zinc, and agricultural commodities like cardamom and cotton. It does not trade company stocks. For international commodities like gold and crude oil, MCX trades until 11:30 PM IST to track US market movements on COMEX and NYMEX.
Which is better — BSE or NSE for stock investing?
For large-cap stocks, NSE generally offers better liquidity and tighter spreads. For small and micro-cap investing, check whether the specific company is listed on BSE SME or NSE Emerge, as some smaller companies list on only one exchange. For derivatives (Nifty, Bank Nifty), NSE is dominant. Your broker routes orders automatically in most cases.
Is MCX regulated by SEBI?
Yes. MCX has been regulated by SEBI since 2015, when the Forward Markets Commission (FMC) was merged into SEBI. All three exchanges — BSE, NSE, and MCX — fall under SEBI's jurisdiction, though MCX operates under separate commodity market regulations.

The screener lets you discover companies across NSE and BSE by filtering on these AI signals — not just financial ratios, but what management actually said in their last earnings call.
MCX commodity trading is a separate discipline and is not covered by StockMirror's earnings analysis, since commodities don't have quarterly earnings calls the way listed companies do.
