Stock Market FAQs
What is the stock market?
The stock market is a network of exchanges, like the NYSE and Nasdaq, where shares of publicly traded companies are bought and sold. When you buy a share, you're buying a small ownership stake in that company.
How do stock prices change?
Prices move based on supply and demand. When more investors want to buy a stock than sell it at the current price, the price rises; when more want to sell than buy, it falls. New information such as earnings, economic data, and news constantly shifts how investors value a company.
What's the difference between a stock, an ETF, and a mutual fund?
A stock is ownership in a single company. An ETF holds a basket of assets and trades on an exchange like a stock. A mutual fund is similar but is priced once daily after markets close and is often actively managed.
What is a market index, like the S&P 500?
An index tracks the combined performance of a basket of stocks to represent a market or sector. The S&P 500 tracks roughly 500 large US companies and is the most widely used benchmark for the overall US stock market.
Is investing in the stock market risky?
Yes. Stock prices can be volatile and can decline sharply over short periods. Diversification, a long time horizon, and avoiding emotionally driven decisions are common ways investors manage that risk. This page is educational and is not personalized financial advice.
