There was some rumor some hedge fund was trying to get out and that cause the PPS to go down(sellin millions of shares). Other explanation is Naked Short selling. MM can sell without borrowing. They can dump million of shares. If Naked short sell happened it will show up in REGSHORT list next week. Other explanation is someone/or some ppl with HUGE position(100million+) just cashing out
Someone spread a scary rumor (is it true? who knows).
The stock took a dump.
Somebody/some bodies stepped in to buy it for a bounce.
The company put out a fluffy press release 20 minutes before the market closes -- on a Friday.
The faithful stay glued to iHub and post about the stock all weekend because they are still wanting the tail number of that F-16 that dropped the bomb.
