We have a bullish signal in SPX ahead of FOMC. I'd assume most people are bearish on the index, since they all expect a drastic reaction to an almost dead certain rate hike by the Fed (I'm not so sure they will actually raise rates this time, or if they do, that the effect will be what people expect).
I'm long a few quality stocks, and recently entered positions in the Argentinian stock market index ETF, ARGT. I'd expect the 2nd target from the election low to be hit soon, roughly: 2528.50. The weekly trend has 2 weeks left, and has already exceeded its forecasted range target, but considering sentiment, Goldman's contrarian signal (downgraded stocks today), the VIX*SKEW signal Tim West discussed today in the KHL chatroom, and the technicals in the SPX chart, I do think we can go a lot higher still. If not long, you may jump in here, risking 1-3 average ranges (14.46-43.38 points) under yesterday's low.
