President Donald Trump's plan for tariffs on imports has guided the stock market's direction over the past few weeks. The initial plan, with double-digit tariffs for countries around the world, shook the market, even pushing the Nasdaq Composite ( ^IXIC 1.61%) to fall into a bear market.

Trump avoids repeating Herbert Hoover’s Smoot-Hawley tariff mistake, which led to companies slashing dividend payouts.
