The night Donald Trump was elected president, Dow futures plummeted as much as 900 points as Wall Street, which overwhelmingly backed the “safe” candidate, Hillary Clinton, worried the unpredictable Trump would break all the dishes in the china shop. Instead, stocks rallied and never looked back. From just before Election Day until the market peaks of Jan. 26, 2018, the Dow Jones Industrial Average DJIA, -1.35%soared 47% and the S&P 500 SPX, -1.42% gained 38% as the new president delivered on his promises to cut regulations and pass a huge corporate tax cut. Of course, the stock market’s fundamentals were strong — and getting stronger — but Trump’s policies clearly helped boost business and investor confidence. But the recent correction showed the potential downside of the Trump presidency — the reemergence of the “bad” Trump. Though prompted by (unwarranted) fears of higher interest rates, the selloff gathered steam when the president announced 25% tariffs on imported steel and 10% tariffs on aluminum imports. As he often does, Trump backtracked and excluded Mexico and Canada (the biggest exporter to the U.S.), but much-dreaded protectionism was back on the table.via
