Thinking about your long-term investment strategies and tolerance for risk can help you decide what type of fund is best suited for you. But you should also consider the effect that fees and taxes will have on your returns over time.

Degrees of Risk

All funds carry some level of risk. You may lose some or all of the money you invest — your principal — because the securities held by a fund go up and down in value. Dividend or interest payments may also fluctuate as market conditions change.

Before you invest, be sure to read a fund's prospectus and shareholder reports to learn about its investment strategy and the potential risks. Funds with higher rates of return may take risks that are beyond your comfort level and are inconsistent with your financial goals.
