A passive fund is an investment option that utilizes a market index or a specific market segment to determine its portfolio's composition and identify potential investment opportunities. This approach differs from active funds, as the fund manager does not actively research individual stocks for inclusion in the portfolio. Instead, passive funds rely on the overall performance of the chosen index or segment to guide their investment decisions. This strategy offers a more hands-off approach for investors, with the goal of achieving a return in line with the chosen market benchmark.
