Index Fund
What Is an Index Fund?
An index fund is a type of investment fund designed to track the performance of a specific market index, such as the S&P 500. Instead of selecting individual securities, the fund invests in the same securities included in the index.
Index funds are typically passively managed, meaning they aim to replicate the performance of the index rather than outperform it.
Why It Matters
Index funds offer investors a simple and cost-effective way to gain diversified exposure to a broad segment of the market. Because they require less active management, index funds often have lower fees compared to actively managed funds.
Many long-term investors use index funds as a core component of their portfolios.
How an Index Fund Works
An index fund mirrors the composition of the index it tracks.
For example, an S&P 500 index fund holds shares of the companies included in the S&P 500 in roughly the same proportions.
When the index rises or falls, the index fund’s performance generally follows the same trend.
Index funds may be structured as mutual funds or ETFs.
Example
An investor buys shares of an index fund that tracks the S&P 500, gaining exposure to hundreds of large U.S. companies through a single investment.
Index Fund vs Actively Managed Fund
- An index fund passively tracks a market index.
- An actively managed fund attempts to outperform the market by selecting securities strategically.
