I personally think investors were just looking for a reason to take profits...like you said few weeks ago things looked great and then earnings fall a little short (yet full year estimate is same) and stock drops $3. I think the fact that the general market was also down big the last few sessions played into it as well just making investors that had profits hit the cash register sooner. I for one took this as an opportunity to get more shares as well as some call options for the next 6 months and expect ebay to slowly climb its way back to the upper 50's if not higher. But then again I still have to go to work every day so what do i know!!!!!
If I've said it once, I've said it a millions times. Try selling on eBay and see what you think of the company. Better yet, try contacting customer service, which is outsourced to the Philipines and see if the fees they charge are worth what they're offering customers.
