The Index Fund Revolution

Index funds are simple, low-cost ways to gain exposure to markets. They’re most commonly available as mutual funds and exchange traded funds (ETFs). While stocks, bonds, commodities and real estate have been around for centuries, index funds have revolutionized how investors access these assets.

What to know about index funds

Round out your knowledge of indexing, ETFs and index mutual funds.

  • Indexing has democratized investing.

    Institutional investors were the first adopters of index funds, more than four decades ago. Individuals quickly followed suit, thanks to the funds’ low cost, diversification and simplicity.

  • Indexes come in all shapes and sizes – including those that track the same market.

    For example, indexes that track U.S. dividend-paying companies can have different rules on stock selection, leading to vastly different results.

  • Index funds can offer access to many of the same outcomes that actively managed funds do.

    Technology has made it possible to index strategies that were once only the province of active managers, such as smart beta ETFs that isolate factors like value, growth and low volatility.

  • Cost is only one consideration in choosing a fund.

    While the annual expense ratio matters, you should make choices based on what’s important to you, be it tax efficiency, tracking error or types of companies in the index.

  • Index funds are professionally managed.

    There’s a lot of work that gets done behind the scenes by skilled portfolio managers to help their funds deliver what they say “on the label.”

Index funds are still a small portion of
stock and bond markets

Index funds have plenty of room to grow. They represent just 10% of global stocks and bonds and about a third of managed assets overall.
