What is a stock (share), in simple words?
A stock is a small piece of ownership in a company. Buy one share of Reliance and you own a tiny slice of the business — and its profits.
A stock — also called a share or equity — is a unit of ownership in a company. When a company lists on an exchange like the NSE or BSE, it divides its ownership into millions of shares and sells some to the public. Buy one share and you legally own that fraction of the business.
You make money from a stock in two ways. The price can rise if the company grows and more people want to own it (capital gains), and the company may share part of its profit with you directly (a dividend). You also take the downside: if the business struggles, the share price can fall and you can lose money.
Owning a share is not a lottery ticket — it is a claim on a real business's future earnings. That is why, over the long run, a stock tends to follow the company's actual performance: revenue, profit, debt, and how well it is run. The whole point of researching a company before buying is to judge those things.
Example
If a company is worth ₹1,000 crore and has 10 crore shares, each share represents ₹100 of the company. Own 100 shares and you own ₹10,000 of the business (1/1,000,000th of it).

Common questions
Is buying a stock the same as gambling?
No. A share is ownership in a real company that earns money. Prices swing in the short term, but over years they tend to track the business. Gambling has no underlying asset; a share does.
How do I actually buy a share in India?
You open a demat + trading account with a SEBI-registered broker (Zerodha, Groww, Upstox, etc.), add money, and place a buy order on the NSE or BSE. The share then sits in your demat account.
