Index drops to worst levels since April 25
The declines in the S&P 500 are accelerating into the final hour of trading.
Fed week is always a choppy week of trading as volumes begin to dry up before the decision. At the moment, worries about Brexit and the potential for hawkish Fed commentary are dominant.
Technically, the drop opens up plenty of downside. The next bit of minor resistance is the 55-day moving average at 2073.
