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.

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
