Zeev, I have to wonder whether any decline before the end of expiration week gets stopped at about 1875-1880 or QQQ 34 considering the enormous quantity of open qqq puts at that level. I don't recall ever seeing such a large (470k) open interest of puts at any strike before. They've built up mostly in the last couple of months. 1875 is also the lower b band, and that level provided support on the last dip in the third week of November.
