Actually, some stocks are on the pinks just because they got lost in the schuffle
I think it was 2 years ago, and maybe the ticker was OBGJ, OB something. The stock was DEAD at 0.06
Then a PR came out that it was being bought out for 5 bucks a share. For 0.60 you could buy all you wanted for several days, It was being shorted by non-believers. Eventually the buyout DID happen and the shorts had to cough up 5 bucks for every share they shorted. OUCH
