speculation, in a nut shell, on why sp moves?

So many posters , both for and against.

I used to own BLY (bought at .13), but sold out around .18 with big rises in play.

Now that it has gone up and down, does anyone care to outline (in a nut shell pls) whats the speculation for the rise and then follow on story behind the dump?

Sorry, I am sure its in the many posts somewhere, but would appreciate the good and the bad, then I'll compare this to my own research/facts.

Thanks
(PS posts like, "its a dog stock" or "this stock will be worth $1million dollars!!! (pinky in mouth)do not add value)
