What is an index fund?

• A. A mutual fund or ETF constructed to match the performance components of a market index.
• B. An actively managed fund aiming to beat the index.
• C. A fund that excludes all ESG data.
• D. A fund that selects stocks randomly.

Answer: (A)

Index funds are mutual funds or ETFs designed to mimic the performance of a market index by holding the same securities in the same weights as the index. The goal is to match the index’s returns, typically with lower costs, because the management is passive rather than trying to pick winners. An actively managed fund, by contrast, seeks to beat the index through security selection and market timing, which is not how an index fund operates. The idea of excluding all ESG data isn’t a defining feature of index funds—there are ESG index funds that track indices based on environmental, social, and governance criteria. A fund that selects stocks randomly wouldn’t track a defined index, which has a specific composition and weights.
