With a company that awful, one might be able to make some money going long on a short squeeze.
Explanation for non-stock-traders:
Normally you make money by buying it at a low price and selling at a higher price. (If you're lucky and the price goes up.)
Short selling is when you do it backwards... to make money, first you sell the stock at a high price and later you buy it back at a lower price. (Again, if you're lucky and the price drops.) How do you sell a stock you don't own? You need to borrow from another trader.
After you sell it, you MUST buy it back at some point so that you can give the stock back to the trader you borrowed it from.
(You can lose your shirt short selling because stock prices can continue to rise for a long time, and you might have to buy it back when the price has gone up, say, 10 fold. Or 100 fold.)
If there's anybody still with me, I'll tell you what a short squeeze is:
Suppose you shorted Trump's stock. After some time Trump decides to sell his shares, at which time the price drops because demand for the stock is low. A lot of traders have shorted the stock and now need to buy it back. With all these traders buying the stock back at the same time, demand is suddenly HIGH and the price skyrockets.
Here's an example of a short squeeze:
Now, if instead of shorting the stock you decide to go long, that just means you buy and sell the normal way. You buy the stock well before Trump dumps his shares, when the price is "normal." Then you wait for the short squeeze and you sell at the high price.
In all honesty, I would never short a stock that is owned by a small number of people. You can be forced to buy the stock back at any time by the trader you borrowed the stock from. Going long is a better choice for this Trump stock IMO. Unless you miss the squeeze... in which case you're hosed.
