We're finally starting to get some volatility back in the markets, and while we may see a bounce into October. expiration, there's some bigger trends in play that I'm looking to continue. Carter says he has not seen this type of movement since the summer of 2011 where there was a 20% decline in three weeks. At levels here that would take the SPX to about 1600, which could actually be normal as that level, believe it or not, took us into the uptrend. Some things to look at that may be different than the last time is the movement in RUT, weakenss in energy and strength in the dollar. Carter recommends playing the trends whether to the long or short side. One stock to watch long is Twitter versus buying the dip in priceline.com and trying to catch a falling knife.
