It certainly is fun to watch for outsiders. I saw the name plastered positively all over the news today under 'Biggest Gainers' headlines, touting the 8% gain at lunch hour and the tremendous 22% gain near close.
If somebody is not so great at math it sounds like a giant step to recover some of the 70% loss on Friday. But in reality they need 8 more days like today's 22% to get back to where they were. That's kind of tough. I wouldn't want to be the guy planning to hold PSN for the next three months, crossing my fingers hoping that their next release does not send it down to 3$.
