not sure of the day but the week will end between 265 and 270 as that is the area that skins the most call and put option buyers. If you look at open interest it needs to close below 270 for the majority of friday's call options to expire worthless, and below 265 too many puts get paid off so that is where the price will be manipulated to, or at least that is where some effort will be given to manipulte that price. Given the low volume and price action it looks like it is possible for the big money guys to skin a couple options players.
