With Trump now in office, and all the stuff he's doing, it's becoming clear to me that the American economy is going to tank, and in the near term. It's currently held up by the delusions of trump-supporting or ambivalent financiers and industrialists, but eventually those will be shattered and stock prices will collapse. If I'm right, I want to buy shorts or puts on, well, the entire US economy. Is that something that's possible?
