Short them spam email stocks

I just had a customer on my line that had some issues with spam... and he did say something interesting.... he said just for the fun of it he has been tracking all the stocks from his spam emails... and every single one of them are loosers... now if they had a 50/50 track record its hard to know whats going to happen... but knowing that they are all going to loose... well sounds like a perfict list to short them stocks and retire :)
