I usually haven't been burned on R/S tankers, if I buy after the announcement and buy the panic. I can usually get a bounce before anything happens, but that MDCN thing sucks because our shares were frozen so we couldn't even trade out of it.
I am not a promoter or professional stock trader. I'm a regular guy who enjoys stock trading to make (or lose) a few dollars. I am only responsible for my own trading foibles, not yours...do your own DD.
