Dear Liz: I’m a federal employee with a Thrift Savings Plan account. I’m 35 and have put about $125,000 into my TSP. However, I never changed it from the low-risk G fund so it’s not gaining as much interest as it should. Should I wait for the market to tank before moving it around or is it OK to move it now due to my age and amount of time I have before retirement? I’m worried I’ll move it and I’ll lose the value in a downturn, so maybe I should wait for a downturn to act.

Answer: You sent this question a few weeks ago, before the recent correction. Did you use the downturn as an excuse to hop into the market? Or did you stay on the sidelines, worried it might drop further?

Many people in your situation get cold feet. You’re better off in the long run just diving in and not trying to time the market.

Waiting for a downturn sounds good in theory, but in reality there’s no sure way to call the bottom of any stock market decline. And when the stock market recovers, it tends to do so in a hurry. If you delay too long, you risk missing much of the upside.

It won’t feel good if the market plunges a day, a week or a year after you invest your money, but remember that you’re investing for the long term. The day-to-day or even year-to-year gyrations of the stock market don’t matter. What matters is the trend over the next 30 years — and long term, stocks outperform every other asset class.
