Alphi, I believe the October thing was a hedge fund set up to buy, sell then go short to pound the stock once the report was found false.
The fake report was "news" even if it was fake and everyone could point to it as a catalyst as to why there was a high volume price spike and plunge that day. Friday there was absolutely nothing anywhere that I have found. No Pacer, profound SA article or even wild rumor speculation was evident, yet we saw a price and volume explosion on.....nothing.
As I said before, I have not seen this happen to Vringo in the year I have followed its daily trade. If anyone knows of a specific day that traded on nothing in the last year, please point it out and I will investigate it. About six weeks ago I posted 47 stock charts to prove that there was a high volume spike on the day the final Russell 2000 reconstitution occurred. So I am not shy about doing a thorough investigation.
