If these players decide to act irrationally, then you'll go bankrupt faster than they will. This is why you don't short industries, you only short companies. Industry will eat you alive. There are also strategy and tactics. Musk can fend off the short siege even though they might collectively have more resources than he does. If you want to beat someone in the market, your better bet is to enter it yourself than to try to bet they're going to fail. Trying to use a short maneuver to expose market irrationality is not for the faint of heart. It never was. Shorts were only ever really useful to try to profit off of stupidity, not irrationality.
