GS reversed at the 160 level we've been talking about for several days. If you're a bull you want that level and then the 200 SMA taken out with force.
IYR reversed at the 50 SMA and is leading the market down -- be patient and wait for that to be remounted.
Whether one likes it or not oil stocks are a big part of the current market -- wait for XLE to re-gain the 50 SMA.
