Target date funds have become the default retirement investment for millions of workers, managing over $3.5 trillion in assets. But are they actually the best choice for your 401(k)?

How They Work

You pick a fund based on your expected retirement year (e.g., Target 2055 Fund). The fund automatically shifts from aggressive stocks to conservative bonds as you age through a process called a glide path.

Pros

Cons

For most retirement savers, target date funds from low-cost providers like Vanguard or Fidelity are an excellent choice that outperforms the average DIY investor.
