More mutual fund companies are charging 401(k) participants for moving money around in their plans, The Wall Street Journal reports.

Vanguard Group, which has long charged individual investors in many of its funds a 1% fee if they sell shares within a year of purchasing them, is to extend these fees to retirement plans beginning Dec. 31.

"Fees could potentially be triggered by annual rebalancing of 401(k) portfolios, but many plan participants don't rebalance within a year," said John Demming, Vanguard spokesman.

Employees enrolled in company retirement plans used to fly under the radar when trading in and out of funds within a short time span.
