Target-date funds are designed for investors with a specific retirement date in mind, automatically adjusting their investment mix to become more conservative as that date approaches. 

These funds typically hold a variety of mutual funds rather than individual stocks or bonds, making them a diversified “fund of funds” that simplifies asset allocation. Early in an investor’s career, target-date funds emphasize growth by leaning heavily on equities, then gradually shift toward bonds to preserve capital as retirement nears. 

Each fund follows a predetermined glide path, which guides the transition from aggressive to conservative investments over time. Investors benefit from a hands-off approach, as the fund handles rebalancing and risk adjustments without the need for active management. 

Finsum: Overall, target-date funds offer a convenient, age-based solution that combines diversification, risk control, and simplicity in a single investment vehicle.
