Yahoo has a target price of $23.50. Intuit has an intrinsic value of $22.60. So when the shorts reappear it will be after this run up has run its course and CRUS is either close to or above either of the target prices.
But again when you look at the history of earnings with CRUS, from now until Sep is when CRUS makes most of its money, so shorting during this period would seem to have a high risk of loss and little possibility of reward.
Additionally, all CRUS would have to do is announce a new breakthrough or product or addition of a major customer or perhaps just an uptick in oil and gas drilling and the shorts would be screwed.
Personally, I think they would be wise to stay away from CRUS.
