The stock market is where shares of companies and other financial instruments are bought and sold. It's a network of all-stock trading where investors and traders buy and sell stocks. These trades determine stock prices, reflecting the company's perceived value and market conditions.

The way you make money from stocks is by the selling them at a higher price than you bought them. For instance, if you bought a share of Apple stock at $200 and sold it when it reached $300, you would have made $100 (minus any taxes you'd have to pay on the money you made)
