I am a proud flipper (wasn't Flipper a dolphin? I hope I don't end up in a can of cheap Tuna flavored catfood . . . )who buys a lot on down swings (through programmed trading) and sells most of it on targeted upswings. I always accumulate a bit on each series of transactions on the hopes of an eventual big scale upswing.
I did lose a tremendous amount in 2000 & 2001, but have made those loses up many times over and am continuing to accrue, granted at a less frentec pace than in the past.
