In the “old days,” when good news was reported, the Stock Market would go up. Today, when good news is reported, the Stock Market goes down. Big mistake, and we have so much good (great) news about the economy!

Actually, it is not a “mistake”; most economists agree that it is a correction (and an overdue one).
So… Trump takes credit when the market is going up, but when it goes down, he blames the stock market itself.
