Index Funds vs. ETFs

On February 16, 2025 By newsroom Topic: Saving And Investing Money

Index funds and ETFs (Exchange-Traded Funds) are both popular investment vehicles offering diversification and low costs. While they share many similarities, some key differences may influence your choice.


Differences Between Index Funds and ETFs

  • Trading Flexibility
  • Index Funds:
    • Can only be bought or sold at the end of the trading day at the day’s closing price (NAV).
  • ETFs:

    • Traded throughout the day like stocks at fluctuating market prices.
    • Better for investors who value intraday trading flexibility.
  • Minimum Investment

  • Index Funds:
    • Often have higher minimum investment requirements (e.g., $1,000 or more).
  • ETFs:

    • Typically require only the price of one share (or less if your broker offers fractional shares).
  • Tax Efficiency

  • ETFs:
    • More tax-efficient due to how trades are structured (investors trade with each other directly).
  • Index Funds:

    • May trigger capital gains taxes for all investors when the fund sells securities to fulfill redemption requests.
  • Cost of Ownership

  • Index Funds:
    • Lower upfront fees (no bid-ask spread).
    • Some brokers waive transaction fees.
  • ETFs:
    • May incur trading costs like bid-ask spreads and commissions, but many brokers now offer commission-free ETFs.

Shared Benefits of Index Funds and ETFs

  • Diversification
  • Both provide exposure to multiple securities in one package, reducing risk.
  • Example: An S&P 500 index fund or ETF offers stakes in 500 large U.S. companies.

  • Low Costs

  • Both are passively managed, tracking an index (e.g., S&P 500), resulting in lower expense ratios compared to actively managed funds.
  • Common expense ratios: Less than 0.05% annually for many funds.

  • Strong Long-Term Returns

  • Both have historically delivered reliable long-term growth, averaging about 10% annually for S&P 500-based investments over the past 90 years.

Which Should You Choose?

  • Choose Index Funds if:
  • You prefer set-it-and-forget-it investing.
  • You’re not concerned with intraday trading flexibility.
  • You’re okay with meeting minimum investment requirements.

  • Choose ETFs if:

  • You want intraday trading flexibility.
  • You have a smaller budget or prefer to invest in fractional shares.
  • You prioritize tax efficiency and want more control over capital gains.
