Not really suddenly appearing, posters like dwhale have been on the money and posting their opinion and analysis for months and months, it just so happens that share price is doing what he was saying now, yet was ridiculed, and the poster vmk research that was loved and getting a lot of praise for his posts BUT was dead wrong, and infact sold his holdings into the people buying his story, after him saying "we are a better quality investor with a long term horizon and dont flip the shares shortly after getting allocation" , he pretty much did exactly what he said he wouldnt. DYOR holders and dont believe these posts online, price is king.
