Is that because shorting a stock involves unlimited risk?

Yes, also it’s the fact that you are rooting for a company to do poorly. I’m just not built that way. I’m an optimist.

This doesn’t mean I’m not wanting a correction in the market, but it’s to buy sold companies at a discount, versus wanting them to do poorly.
