After giving Trump some credit, the article goes on....
But that shouldnt let Trump off the hook. While markets, like wayward elephants, do tend to have minds of their own, its also possible to identify specific ways in which Trump has contributed to the downturn. His prosecution of the trade war with China, in particular, has rattled investors. The 90-day truce between the two nations, agreed upon at the Group of 20 summit in Buenos Aires on Dec. 1, has done little to buoy the stock market because investors realize that hostilities could erupt again when the cease-fire ends in March. The S&P 500 price-earnings ratio has fallen 13 percent since September. Trump, in general, was the No.?1 thing keeping institutional investors awake at night in a mid-December survey by investment bank RBC Capital Markets.
Trumps Twitter attacks on Powell could also be backfiring. Even some market analysts who think the Fed should back off from raising interest rates say that the presidents messaging could induce Powell to demonstrate his independence by forging ahead with unnecessary hikes. Or, for bond investors worried that the Fed will accede to the president, theres an expectation of accelerating inflation. That would cause bond prices to fallwhich generally causes stock prices to fall as well.
Trumps leadership style is also wearing poorly. His strategy of keeping people guessing and off balance might work well with adversaries, but it alienates friends. Im not aware of another U.S. president trying to weaponize uncertainty. And for good reason: It harms American interests as well as foreign ones, says Steven Davis, a professor at Booth who helped develop an economic policy uncertainty index. (The news-based version of the uncertainty index is just below the top 10th of its 34-year range of values.)
Its true that the stock market isnt the best metric for judging a president. Stocks can go up even if the president is performing badly and down even if hes doing well. For example, just because getting tough on China is bad for some tech stocks doesnt mean its the wrong thing to do. Conversely, many of the things that are most troublesome about Trump dont show up in stock indexesthe coarsening of the public discourse, the damage to Americas global alliances. And some potentially harmful actions, such as trying to weaken rules on mercury emissions from coal plants, could boost certain stocks.
