I don't do the Dow gambit myself, I had JNJ (and have BA) independently of the gambit. The gambit is for those they are not facile at day trading and I just point to the gambit opportunity, when such arise, it did twice so far this year for a clean 40% plus, a conservative player should say "thank you" and just watch (for months maybe) until another gambit opportunity arises. I am not exactly your "conservative" player.
