I have been long and made a nice profit on OPTR but it turns out that pro was correct - at least to this point. Sure can't make any money by calling people names. I sold most of my holdings at $16+, the remainder at $11+.
I may re-enter about the time pro says he'll be covering. Fido remains a good drug for a serious condition but sales have been less than I hoped. But longer term the company may turn out to be a good investment, just not now, as I see it.
