Ownership of a slice of a company, which can rise or fall in value.
Equity, or stock, represents partial ownership in a company. Shareholders can benefit from price appreciation and dividends, but also bear the risk of loss. Over long periods stocks have delivered higher returns than bonds or cash, which is why they anchor most long-term growth portfolios despite short-term volatility.
Owning equity index funds gives you a stake in thousands of companies' future profits.
