Mutual funds pool money from many investors and hand it to a portfolio manager. They've been the default workplace retirement option in the US for decades.

Use this checklist before committing to any mutual funds listed above: editorial criteria that consistently separate well-run products from the rest. Each point applies to most listings in the category, including those we have not yet reviewed in detail.
Add the expense ratio, any 12b-1 fee, and amortized loads to get the real annual cost. A 1.0% all-in expense versus a 0.05% index alternative compounds into a six-figure gap on a long-horizon retirement portfolio. Treat fees as the single most controllable variable.
If you're paying for active management, find out who's managing the money. Long-tenured managers with consistent process can be defended; revolving-door teams or 'star manager' funds where the star recently left rarely are. Portfolio turnover above 100% means the fund replaces its holdings annually.
Look at after-tax returns published in the prospectus and the fund's recent history of capital-gains distributions. Funds that frequently issue large distributions are best held inside tax-advantaged accounts. Index funds typically distribute very little; many active equity funds distribute a lot.
Confirm the fund actually competes with the benchmark it cites. A large-cap growth fund benchmarked to the broad S&P 500 may look great in growth markets and miserable when value leads. Compare against an index that reflects the same style and geography.
Mutual Funds are actively managed funds. The five short sections below walk through how they work, who they suit, the main risks, where they fit in a broader plan, and the US regulatory rules that govern them today.
You buy shares directly from the fund company at the day's closing net asset value. The manager invests the pooled money in stocks, bonds, or both, in line with the fund's prospectus.
Active funds try to beat a benchmark and charge for the attempt. Passive funds simply track an index. After fees, the majority of active funds underperform a low-cost index over long periods.
High expense ratios and 12b-1 fees can quietly eat returns. Some funds also charge sales loads or short-term redemption fees. Tax-inefficient trading inside the fund can create surprise capital gains distributions.
Mutual funds are still the dominant vehicle inside 401(k) and 403(b) plans, where ETF availability is limited. Target-date funds in particular are sensible defaults for hands-off retirement savers. In a taxable brokerage account, the ETF wrapper is usually preferable for tax efficiency.
Mutual funds are SEC-registered investment companies under the 1940 Act. Each fund publishes a statutory prospectus and an annual report. Workplace retirement plans are governed by ERISA, which obligates plan sponsors to vet and monitor the fund menu.
These are the terms you will see most often across mutual funds listings, statements, prospectuses and support docs. Skim them once so the rest of the page, and every product page in this category, reads cleanly the next time you visit.
