I shorted CSL 10 days ago now have 10 000 shorts, it is very expensively priced and I know the company and market well after killing BTA Biota. The lower exchange helps and it is probably considered the best growth stock on the market. My research indicates it should be priced at $50 and is very susceptible to damage with the immunisation area. I really cant see it going to $80 so upside it limited. I feel it is a solid short if you feel the market will tank (insurance). Doesn't move very much and lousy dividend. If you are new to shorting this would be the safest stock.
