DAC I fly without stops. Crazy I know, but after you've had a biotech or two dip under a certain price for a moment only to get bought out the next day you don't do that anymore. Besides my losers tend to be cataclysmic- stops won't work in fact they just guarantee you get out at the low. In a bull market with the IBD 100 I'm sure you can make money, but it's heard mentality stuff, my thinking really freed up and I started to be in stocks BEFORE they went up when I stopped relying on IBD.
