On friday the senate passed a bill that would make internet gambling illegal. See below for what happened to Party Poker (largest poker room) on the London stock exchange.: http://finance.yahoo.com/q/bc?s=PRTY.L&t=5d I'm a poker player so I was watching this stock with interest to see what would happen. I was pretty confident that the bill would pass and it did by a large margin, effectively crushing all internet gambling stocks. Now that I've seen what congress can do, I'm interested in playing stocks for big moves facing upcoming legislation. I've read enough to know that many small time investors get killed doing similiar to what I am proposing (Trading on heavy speculation) My question is, is this a fools game or can a rational, sensible investor make money doing this?
