True or False: Before you invest, you should ensure a mutual fund has performed well for 5-10 years.

The statement that you should ensure a mutual fund has performed well for 5-10 years before you invest is indeed true. A solid track record of performance over a significant period, such as 5 to 10 years, can indicate the mutual fund's ability to navigate different market conditions and economic cycles. It provides investors with insight into the fund's historical returns, consistency, and management effectiveness.

Long-term performance can reflect how well the fund managers have implemented their investment strategies, adjusted for risk, and generated returns for investors. This historical data can help prospective investors gauge whether the fund aligns with their investment goals and risk tolerance.

However, while historical performance is an important factor to consider, it shouldn't be the sole criterion for investment decisions. It's also vital to evaluate other aspects such as the fund's fees, the investment strategy, and how it fits into the overall portfolio, especially as past performance is not necessarily indicative of future results.
