Why do stocks tend to be a riskier investment than bonds?

Stocks tend to be a riskier investment than bonds because they represent ownership in a company, which can be highly volatile and subject to market fluctuations, economic conditions, and company performance. Unlike bonds, which typically offer fixed interest payments and have a higher claim on assets in the event of bankruptcy, stocks may not guarantee returns and can potentially lose all value. Additionally, stock prices can be influenced by investor sentiment and external factors, making them more unpredictable than the generally more stable returns of bonds.
