What Is an Index Fund?
An index fund is a type of investment that tracks a market index, such as the S&P 500 or the Nasdaq Composite. Instead of trying to beat the market by picking individual stocks, index funds aim to match the performance of their target index by holding all (or a representative sample) of the securities in that index.
Why Choose Index Funds?
Low Costs
Index funds typically have much lower expense ratios than actively managed funds because they:
- Don’t require teams of analysts
- Have lower trading costs
- Follow a passive investment strategy
Built-in Diversification
When you buy an index fund, you’re instantly investing in hundreds or thousands of different companies, which helps spread your risk across various sectors and companies.
Proven Track Record
Historically, index funds have outperformed the majority of actively managed funds over long periods. This is partly due to their lower fees and the difficulty active managers face in consistently beating the market.
