With equities climbing into the monthly/Q3 close, price momentum on the giant monthly cycle turned positive. The September settlement was the most bullish since Feb'2015.
September was the first monthly settlement with the MACD (blue bar histogram) in positive territory since Feb'2015. Its pretty significant, and confirms the underlying market upside seen since the Jan/Feb' lows.
In theory, the market could battle all the way into spring 2017.
First soft target is the upper bollinger, which in early Oct' will be somewhere around sp'2210.
Things only turn bearish with sustained price action below the monthly 10MA, which is currently @ 2075.
