In passive fund management, investors attempt to achieve market returns instead of trying to outperform the market through active stock selection. This strategy typically involves buying a diverse set of investments that are part of a market index, such as the S&P 500, and holding them for an extended period. Passive managers often use exchange-traded funds (ETFs) or index funds, which have lower management fees compared to actively managed funds. The main goal is to achieve returns that are in line with the overall market rather than seeking individual asset outperformance.
