What Are Stocks?
A stock is a share of ownership in a company. Buying one makes you a part-owner of that business, with a claim on its future profits and, in many cases, a vote on how it's run.
Why People Invest in Stocks
Stocks have historically offered some of the strongest long-run returns of any widely available asset class, making them a core building block for retirement savings, education funds, and long-term wealth building.
How Stocks Work
Shares trade on exchanges like the NYSE and Nasdaq, where prices move constantly based on supply, demand, company performance, and the broader economy. You can buy or sell through a brokerage account, typically in seconds.
Benefits and Risks
Stocks can appreciate in price and pay dividends, but their value can also fall sharply and quickly. Diversification, time horizon, and risk tolerance all shape how much of a portfolio belongs in individual stocks versus funds.
