Trying to pick individual stocks is a losing game, and this doesn’t just apply to individual investors. It’s also true for professionally run, actively managed mutual funds.
Actively managed funds are tasked with picking a collection of stocks and bonds that will outperform market indices, or benchmarks, such as the S&P 500 or the Dow. They’re armed with Ph.D. analysts, hundreds of interns, and tools and research to which very few of us have access — but they can’t consistently beat their benchmarks by enough to justify their costs.
Some managers do outperform the market, but picking a winning manager is as tricky as picking winning stocks. If you still think you can find “a good manager” who is the exception, consider this widely accepted Wall Street rule of thumb: Past performance doesn’t guarantee future performance. A manager who outperformed last year may not do it again this year.
