>so profit off it then? Many already have, as they're the ones that sold to investors. And for any that chose to remain on the sidelines, not footing the risk can be pay off enough. Shorting however, isn't about predicting a bubble, but predicting if/when it bursts. And that's not an easy prediction to make as investors can choose to sit on unrealized losses indefinitely, if they're not over leveraged or needing to realize them.
