As U.S. markets continue to suffer steep declines in the wake of the Trump administration’s new tariff policies, you may be wondering what the next best move is when it comes to your retirement portfolio and other investments.

Behavioral finance experts warn now is the worst time to make any drastic moves.

“It is dangerous for you — unless you can read what is going to happen next in the political world, in the economic world — to make a decision,” said Meir Statman, a professor of finance at Santa Clara University.

“It is more likely to be driven by emotion and, in this case, emotion that is going to act against you rather than for you,” said Statman, who is author of the book, “A Wealth of Well-Being: A Holistic Approach to Behavioral Finance.”

That may sound easier said than done when headlines show stocks are sliding into bear market territory while J.P. Morgan is raising the chances of a recession this year to 60% from 40%.

“When the market drops, we have sort of a herd instinct,” said Bradley Klontz, a psychologist, certified financial planner and managing principal of YMW Advisors in Boulder, Colorado. Klontz is also a member of the CNBC FA Council.

That survival instinct to run towards safety and away from danger dates back to humans’ hunter gatherer days, Klontz said. Back then, following those cues was necessary for survival.

But when it comes to investing, those impulses can backfire, he said.

“It’s an internal panic, and we’re just sort of wired to sell at the absolute worst times,” Klontz said.

The Trump administration’s plan to slap steep tariffs on goods from dozens of countries is expected to spike prices for consumers. Some items, like leather goods, will see a bigger jump than others.

The overall impact on households will vary based on their purchasing habits. But most families — especially lower earners — are likely to feel the pain to some degree, economists said.

According to an analysis by the Budget Lab at Yale University, the average household will lose $3,800 of purchasing power per year as a result of all President Donald Trump‘s tariff policies — and retaliatory trade actions by other nations — announced as of Wednesday.

That’s a “meaningful amount,” said Ernie Tedeschi, the lab’s director of economics and former chief economist at the White House Council of Economic Advisers during the Biden administration.

The analysis doesn’t include the 34% retaliatory tariff China announced Friday on all U.S. exports, set to take effect April 10. The U.S. exported nearly $144 billion worth of goods to China in 2024, the third-largest market for U.S. goods behind Canada and Mexico, according to the Census Bureau.

Under the “reciprocal tariffs” Trump announced Wednesday, Chinese imports will face a 34% duty. Goods from Vietnam, Sri Lanka and Bangladesh face tariffs of 46%, 44% and 37%, respectively.

Taking into account the pre-existing tariffs on China totaling 20%, Beijing now faces an effective tariff rate of at least 54%.

“The tariffs are disastrous for the apparel industry worldwide, but especially for smaller countries with highly specialized garment manufacturing,” Green said.

A lot of clothing production has moved overseas over the last 50 years, Tedeschi said, but it’s “very unlikely” clothing and textile manufacturing will return to the U.S. from Asia in the wake of the new tariffs.

“People will still import clothing to a large extent, and they’ll have to eat the price increase,” he said.

The duties announced Wednesday are on top of other tariffs Trump has imposed since his second inauguration, including duties on automobiles and car parts; copper, steel and aluminum; and certain imports from Canada and Mexico.

The cost of motor vehicles and car parts could swell by over 8% according to the Yale Budget Lab analysis.

Bank of America estimated that new vehicle prices could increase as much as $10,000 if automakers pass the full impact of tariffs on to consumers.

“Rising car prices are already a major pain point for the vast majority of Americans who live in an area where they need a car to get to work, school, their kids’ activities, and medical appointments,” said Erin Witte, director of consumer protection for the Consumer Federation of America.

“These tariffs will make it much worse, and will significantly reduce Americans’ choices about what car they want to buy,” she said.

Tariffs on specific commodities like aluminum and steel affect consumers indirectly, since the materials are used to manufacture a swath of consumer goods.

White House spokesman Kush Desai pushed back on analyses that prices will spike because of Trump’s tariff policy.

“Chicken Little ‘expert’ predictions didn’t quite pan out during President Trump’s first term, and they’re not going to pan out during his second term when President Trump again restores American Greatness from Main Street to Wall Street,” Desai said in an e-mailed statement.

Trump’s second-term tariffs are orders of magnitude larger than his first term, however.

The first Trump administration put tariffs on about $380 billion worth of goods in 2018 and 2019, according to the Tax Foundation. The tariffs so far imposed in Trump’s second term affect more than $2.5 trillion of U.S. imports, it said.

There’s also evidence that the first-term tariffs raised prices for some consumers.

Retail prices for the typical washing machine and clothing dryer rose by about 12% each — about $86 and $92 per unit, respectively — due to 2018 tariffs on imports of washing machines, according to a study by economists at the Federal Reserve Board and University of Chicago. The increased cost to consumers totaled $1.5 billion a year, the study found.

As the stock market continues to fall, some investors are eager to “buy the dip,” or purchase assets at temporarily lower prices. Financial advisors, however, urge clients to stick with long-term investing plans amid the latest volatility.

U.S. stocks plunged on Thursday after President Donald Trump issued sweeping tariffs on more than 180 countries and territories. The sell-off continued Friday after China unveiled plans to impose a 34% retaliatory tariff on all goods imported from the U.S.

As of Friday afternoon, the Dow Jones Industrial Average was down more than 1,700 points following a 1,679.39 drop on Thursday. Meanwhile, the S&P 500 was off 4.8% after losing 4.84% the previous day. The tech-heavy Nasdaq Composite slid by 4.9% after plummeting 5.97% on Thursday.

If you’re looking for buying opportunities while assets are down, here are some things to consider, according to financial advisors.

Waiting on the sidelines can be costly because the best returns can follow the biggest dips, according to research from Bank of America.

Rather than trying to time the bottom, you should consider “dollar-cost averaging,” which systematically invests your money at set intervals, Spector said. The strategy can capture lower prices while reducing risk, he said.
