Rather than hiring a stock picker to run your investment portfolio, you’re probably better off just investing in market indexes. That advice has been gaining a lot of traction in recent years, especially as those indexes (at least in the U.S.) have reaped big gains in a bull market that’s now entering its ninth year. But data released this week underscores the idea even more forcefully.

More than six in 10 actively managed stock funds were outperformed by their market benchmarks in 2016, according to the S&P Indices Versus Active funds scorecard. Large-cap funds failed to keep up with the S&P 500 66% of the time, while mid- and small-cap funds were outperformed by their benchmarks 89.3% and 85.5% of the time, respectively. As bad as those numbers are, they only get worse over longer timelines. The overwhelming majority of all domestic funds were outperformed by their benchmarks over 1-, 3-, 5-, 10-, and 15-year intervals that ended December 2016.
