Passive management is an investment strategy where a portfolio is designed to match the performance of a market index, like the S&P 500, instead of trying to beat it. Rather than frequently buying and selling stocks, passive managers aim to hold a diversified mix of investments that mirror the index. This approach typically involves lower fees and less trading, which can help investors keep more of their returns over time. It’s a popular strategy for long-term investors who believe in staying the course rather than trying to time the market.
