Actually, the end of month Dow play is real, Zeev. I've posted it on other threads many times. Here's the play:
Take the close from the 3rd to the last trading day of the month (10,342 in this case).
Buy the intra-day low the following day, usually prior to 11:00AM (it didn't come until the afternoon today, however).
You have a near 98% chance to sell at a price at or above the close of the 3rd to the last trading day of the month. Normally observed spread is 100-150 points, with 100 points the norm recently.
I didn't play it this month as I was in other stuff this afternoon, and I was not totally enamored with the Dow still above 10,320 this AM.
It has a success rate that ranks right up there with condoms!
