'Wild time': Wall Street strategists warn of uncertain outlook amid Trump's tariffs

President Donald Trump’s “ Liberation Day ” tariffs set off one of the most volatile periods of stock trading in U.S. history – and uncertainty still looms over Wall Street, analysts told ABC News.

Tariffs remain the primary mover of stock prices, putting market strategists and everyday investors in the near-impossible position of anticipating Trump’s next decision and its potential fallout, the analysts said.

Analysts warned of a possible economic downturn that would pummel stocks but urged investors to hold on to shares if they can resist the temptation to sell, since markets typically rise over the long term.

The Trump administration’s policy swerves “leave the markets kind of baffled, without investors having a clear idea of whether they should hold or fold when it comes to their own stock portfolio,” Ed Yardeni, the president of market advisory firm Yardeni Research and former chief investment strategist at Deutsche Bank's U.S. equities division, told ABC News.

Callie Cox, chief market strategist at Ritholtz Wealth Management, told investors this week: “Trying to predict policy – or markets’ next move – is a fool’s errand.”

After Trump’s tariff announcement in the Rose Garden on April 2, the S&P 500 and Nasdaq suffered their biggest one-day losses since the pandemic. When Trump paused some of the tariffs a week later, the indexes soared, recovering much of their losses. Since then, however, an escalating trade war with tariffs has contributed to topsy-turvy markets.

Each of the major indexes stands lower than it did before Trump’s tariff announcement. The Dow Jones Industrial Average has dropped about 4%, while the S&P 500 has fallen roughly 5%. The tech-heavy Nasdaq has also declined roughly 5%.

As markets swung, bond yields climbed and the U.S. dollar depreciated, prompting concerns about assets that typically serve as safe-haven investments during moments of instability for stocks. The 10-year Treasury yield, which helps set interest rates for mortgages and credit cards, has eased in recent days but stands well above its level at the outset of this month.

“It’s a wild time,” Mike Loukas, CEO of TrueMark Investments, told ABC News.

The volatility poses a challenge for market strategists, since the swings in day-to-day stock prices can be traced in large part to White House policies and announcements, rather than to economic data or corporate profits, analysts said.

Fed Chair Jerome Powell said Wednesday that he expects the tariffs to hike inflation and slow economic growth. Within minutes, stocks plummeted.
