What is a stock, and how do markets actually work?

A share of stock is a small slice of legal ownership in a company. When you buy a share, you become a part-owner: you have a claim on a tiny fraction of the company's assets, future profits, and (typically) voting rights at general meetings.

Companies issue shares in the *primary market* — that's an IPO or a follow-on offering. After that, those shares trade between investors in the *secondary market*: NSE, BSE, NYSE, NASDAQ, and others. The company itself doesn't receive cash from secondary-market trades; investors trade with each other.

Prices are formed by supply and demand at the exchange. Each exchange runs an *order book*: a continuously matched list of buy and sell orders. When a buyer's bid meets a seller's ask, a trade prints — and that print becomes the "last price". The bid/ask spread, depth, and order flow are real-time signals that professional traders watch closely.

For long-term investors, day-to-day price wiggles matter less than the underlying business. Two questions dominate: 1. How much cash is this business likely to generate over the next 5-10 years? 2. What price am I paying for those future cash flows today?

That's the foundation of *fundamental analysis*. *Technical analysis*, by contrast, studies the price chart itself for patterns and momentum. Both have their place. Neither is a substitute for understanding the business.

Risk reminder. Stocks can lose value — sometimes a lot. Past performance is no guarantee of future results, and no amount of analysis can eliminate uncertainty.
