Like I've mentioned before, sometimes stock manipulation goes in both directions. It's suspicious that starting at exactly 90 minutes before Friday's (and options expiriation) close - RIMM moves above $9 with an unexpected 15 million shares on the buy side making all of those $9 calls suddenly in the money.
Then, another buyout rumor gets inserted into the media, giving the MM's that pushed the stock over $9 the opportunity to not only cash in on their $9 call options, but also make a quick profit by dumping these shares onto retail buyers that don't want to miss "the big move".
Unless you have about $100M, the rest of us can't play that game but hedge fund managers can. The stock is already starting to come back in. I unloaded my $9 calls, and I'm confident I'll have the chance to buy them back again in the next few days.
For those longs that aren't taking a little profit here, caveat emptor.
