Don't look at your 401k tomorrow. As Trump's trade war heats up--which the WSJ called the “dumbest trade war in history” (https://www.wsj.com/opinion/donald-trump-tariffs-25-percent-mexico-canada-trade-economy-84476fb2)--market futures are crashing. At present, the pre-market futures are down 1% for the Dow, 1.6% for the S&P500, and 2.3% for the NASDAQ.
Buckle up, it's going to get ugly.
