i've done extremely well shorting this stock. In fact, it's one of the few small cap healthcare stocks that is both shortable and has significantly underperformed in the past year.
it's really not a surprise either: when a company misses consensus 4 out of the past 8 quarters and revises guidance 4 times in the past two years, either the management is incompetent or misleading. Either way, they are not to be trusted as good stewards of investor money.
you would have done better just parking your money in pfizer for the past five years (and collected a dividend along the way).
