Stocks have dropped since Trump unveiled new tariffs. What does it mean for your 401(k)?

U.S. stocks continued to tumble in the wake of President Donald Trump’s Wednesday tariff announcement, raising concerns among investors stashing away money in retirement funds like 401(k)s.

After sharp declines last week, the S&P 500 briefly entered bear market territory ‒ at least a 20% decline from a recent peak ‒ before rebounding Monday morning. The benchmark index was trading at roughly 5,006 points, down 1.35%, as of 11:21 a.m. EDT. The Dow Jones Industrial Average was down 2.08% and the Nasdaq composite was down 1.17%.

Dramatic market plunges can be stressful, especially for those nearing retirement age. But the general consensus among experts? Don’t panic; it could lead to risky moves that hurt you in the long run.

"There’s always an anecdote of somebody that panics ... and it had more negative impact than if they had just tried to ride it out,” said Sarah Behr, a registered investment adviser and founder of Simplify Financial Planning in San Francisco.

How should younger workers with 401(k)s react to stock market dips?

Younger employees who are just starting to build up their retirement accounts should focus on their long-term savings strategy and continue their investments, according to Mark Williams, a risk-management practitioner and lecturer at Boston University.

“When you are in your 20s, that’s the most time you have until retirement that your money can grow,” he said. “It’s really the best time to invest in stocks."

Many Americans follow an investment strategy called “dollar-cost averaging,” where they commit a fixed amount of money to their retirement accounts at regular intervals, regardless of how the market is performing. USA TODAY previously reported that this strategy can reduce the average cost investors pay per share over time because they'll buy more shares when they’re trading at lower prices.

“Just keep the momentum going,” Behr said. “Compounding interest is a really powerful function in retirement, and if you miss the compounding interest because you took 10 years off during the recession, you might miss a big recovery. And you have a chance to buy low with the expectation that it's going to return at some point in the future.”

The wrong move, according to Williams? Panicking and taking money out of those retirement accounts. Especially since 401(k)s typically charge an early withdrawal penalty for removing funds before the age of 59 ½.

“Market drops test investor resolve,” he said. “It is counterproductive to look at your retirement account daily. Instead, view your investments as part of a long-term strategy that will overcome market corrections, grow and support retirement.”
