Same! When it's $100 I want to buy, but if the price falls to $80 i want to sell. Presumably i bought because I thought it was worth more than $100, it would only make sense for me to sell at $80 for a reason other than the price: fundamentals change, some bad event happening. If the only thing that changed is the price, I want to buy more at $80!
