If CEOs were actually wrecking their companies in order to get a fake short term boost, they'd be shortly out of business. If a person was sure a CEO was doing that, they'd be making money shorting the stock.
That's a very high set of both static and scaling costs that eat away any profit you made by being nominally correct. Combined with the risk profile... you can't "just" go short a stock.
And yes, you can hedge losses with options or construct complicated options positions to try to hone in on a specific price movement you're anticpating. Now you have to deal with entering and exiting a complicated multi-instrument position without price slippage, AND you have theta decay and volatility-related price movements also eating away at the core money you're making by being nominally right.
Have people made money? Yes, for sure. There's also a lot of dead bodies and people who barely broke even despite theoretically having been right.
A more productive view would be looking at an index of tech companies - try QQQ.
Or if it doesn't, token inflation will kill their profitability.
A lot of people are putting big money on both sides of those predictions, and they can't all be wrong.
