Understand How the Indian Stock Market Works
Learn how shares, exchanges, indices, orders, Demat accounts and market movements work before you begin investing or trading.
What Is the Stock Market?
Companies issue shares that represent ownership. Investors buy and sell those shares, while exchanges provide the organized marketplace.
Share prices fluctuate as supply and demand respond to expectations, company performance, news, interest rates and broader market conditions. A price move reflects current market activity—not a guaranteed assessment of future value.

These are size classifications. No category is always safer, better or more suitable.

Market Order
Seeks immediate execution at the best available price. Example: buying at the current available ask; the final price can vary.
Limit Order
Executes only at your chosen price or better. Example: a buy limit at ₹100 will not execute above ₹100.
