To Exce26:
I would say, "if a stategy works (and I'm not convinced this one does), then it works. Not just for "Don's 20-30 stocks" but for the vast majority (assuming reasonable criteria used for inclusion in the group, i.e. minimum stock price, avg. daily volume, etc.). Are there some issues that may seldom seem to work for whatever reason (specialist manipulation?)? Sure. But I don't believe Don has uncovered the holy grail; the exclusive 20-30 stocks which work for the OPG. As I said, not if this strategy REALLY works.
