Stocks can only go two ways: Up or Down. So why couldn't a person trade the most active (i.e big price swings) stocks like the top 10 Advance/Declines and just use a mid range stop and be profitable. These stocks usually have HUGE volume and move 10% up or down after the open so you have a decent chance of catching a big move. Yes, you are going to get whipsawed often and maybe even stopped out 3 of 5 times but your 2 profitable trades will be huge winners. Is this a valid idea? Just a thought.
