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.
