The most expanded flash crashes in Probe's trading history were the beginning of sustained strength to new all-time highs. I never forgot what an experienced investor told me years ago at E.F. Hutton on Rodeo Drive in Beverly Hills: "Just before a stock starts moving much higher they take the shares down hard" I remember the man well. He raked in the money by buying Budd Manufacturing(BF-NYSE) on sell-offs in the early sixties.
