I understand what buying long does, but say a BOW strike price is 150 and the price of the shares is the original $5. If you short, does that mean you're betting on the price ONLY being between 150 and 154.99, or are you betting on it cashing out at $0? The way I read it, if it cashes out at zero, it cashes out at zero for everybody and no one wins anything whether you long or shorted it. Is that correct?
