In that case, please feel free to short their stock, and make lots of money.
If you are afraid of the potentially unlimited downside to a short, you can buy an out of the money call option as an insurance. Or instead of shorting directly and insuring that, you can also buy a put option, which gives you the right to sell the stock at a specific price.
