Don’t Overtrade
This is also valid for other types of investment accounts, but it applies to your 401(k) plan in particular. If you overtrade your 401(k) and try to buy and sell stocks based on expected price fluctuations, you might lose the opportunity to increase your investments when the market is high. What’s more, when you overtrade, you’re canceling all the efforts you put in into defining your investment objectives, risk tolerance and portfolio for your long-term goals.
