Investment Funds

are pooled investment vehicles that hold a collection of stocks, bonds, or other assets, allowing you to own hundreds of securities with a single purchase.

ETFs trade like stocks throughout the day. Mutual funds trade once daily. Index funds track a market index passively.

Quick answer

ETFs = trade like stocks, low fees, tax efficient. Mutual funds = trade once daily, some have high fees. Index funds = lowest fees, beat most active funds. For most investors: low-cost index ETFs are best.

ETFs trade intraday like stocks with typically lower fees and greater tax efficiency, while mutual funds price once daily at the closing NAV.

Investment Funds Overview

Instead of buying individual stocks, you can buy funds that hold hundreds of stocks in a single purchase, giving you instant diversification.

ETFs

ETFs trade on exchanges like stocks. Buy/sell anytime during market hours. Low fees (0.03-0.20%), tax efficient, no minimums.

Mutual Funds

Trade once daily at end-of-day price. Often higher fees (0.5-1.5%). Less tax efficient. May have minimums ($1,000+).

Index Funds

A strategy, not a fund type. Passively track a market index. Lowest fees, beat 90% of active funds over time.

Key Takeaways

  • ETFs: best for most investors (low fees, tax efficient)
  • Mutual funds: useful in 401(k)s
  • Index funds: lowest cost, beat most active managers
