Now S+P 500 futures feel some heat as Dow Jones losses deepen

The last time the premarket price for United Health was seen here it was down more than 20% and that has had a profound impact on the Dow Jones futures. That is to be expected given this stock is ranked number one by market cap. So, as the Dow Jones now prices an opening more than 500 points below where it closed last night, at 39,669, it is weighing on the S+P 500 futures. Earlier that index was priced to reopen close to 5,340. The index closed last night at 5,275.70. There have been other earnings reports out this morning that might have helped to support the opening outlook, but right now it is UNH that is driving the S+P futures closer to an unchanged opening just now. The index future is right now falling back further pricing the opening around 5,290
