It is well known that President Trump invests fervent belief in the stock market as a performance measure. When it’s rising, as it often has during his Presidency, he says that his policies are responsible. But what about a week like this with markets in decline, including a steep two-day drop in the Dow Jones average? No logic exists that will allow Mr. Trump to take responsibility only for sunny days. The President is right to believe in market signals.
