Stocks give you partial ownership in a company and the potential for significant capital gains. Historically, the S&P 500 has returned about 10% annually, but individual years can swing widely, making stocks best for long-term investors who can tolerate volatility.

Bonds are essentially IOUs where you lend money to an issuer in exchange for regular interest payments and return of principal at maturity. They provide income stability and help cushion a portfolio during stock market downturns.

When to Use Stocks

  • You have a long time horizon (10+ years)
  • You want to grow your wealth aggressively
  • You can tolerate short-term losses

When to Use Bonds

  • You need stable income from investments
  • You are nearing retirement
  • You want to reduce overall portfolio volatility
