"retire" come on lad, this is a bad stock to short? When this run comes to an end it will be, but at the moment don't even try to short it. It just depends where OVTI is at in its cycle, like I said it only makes sense to be long on OVTI right now [mind you the entry point was very apparent prior to it taking off]. I wouldn't open a new position, but on days like today I'd buy calls then sell them in a week or so prior to the next pullback.
Your just too simplistic in saying this is a bad stock to short or not to short. With OVTI it basically depends on the time of the year to declare if its a good short or good to go long on. You can't tell me going short last october at $23 was a bad idea, and likewise you can't tell me it was a bad idea to go long mid-February at $12.50, you have to be a little more fair.
