Vanguard Target Retirement Funds offer a diversified portfolio within a single fund that adjusts its underlying asset mix over time. The funds provide broad diversification while incrementally decreasing exposure to stocks and increasing exposure to bonds as each fund’s target retirement date approaches. The funds continue to adjust for approximately seven years after that date until their allocations match that of the Target Retirement Income Fund. Investors in the funds should be able to tolerate the risks that come from the volatility of the stock and bond markets. You may wish to consider this fund if you’re planning to retire between 2038 and 2042.
