Every time someone sells short someone is buying. So how is short ratio useful to measure "negative sentiment"?
Short selling might be used for technical reasons. For instance, an option trader might sell put options and at the same time sell the stock short for hedging. If the stock price goes down he loses money on the options but gains when he covers the short sell. That is, he might be betting on variables other than the stock price.
