Conclusion

Target date funds offer the simplest path to retirement investing—one decision and you're done. For most investors, especially those in 401(k)s who want a hands-off approach, a low-cost target date fund is an excellent choice. Choose an index-based fund (Vanguard, Fidelity Index, Schwab) with expense ratios under 0.15%, select your approximate retirement year, and let time do the work.
