It's never the time to short a company, even a really bad one. You have only 100% upside, infinite downside, and you have to time it perfectly. A short can be a part of a combination strategy where you go long on one company and short on a related one, but you still have to be really careful.

If DB stock increases 50% before it crashes, would you be forced to sell at the top and lose all your money?
