Commentary
Last week’s close calls have turned into a prelude.

On Monday, September 28, 2015, the sellers took center stage and full control of the market action. T2108 dropped back into oversold conditions for the third time in a month. This latest plunge defied my expectations for the S&P 500 (SPY) to hold up long enough for retests of resistance at the 50 and 200-day moving averages (DMA).

The S&P 500 follows through on breakdown from wedge of last two oversold periods

T2108 plunges back into oversold territory

The sellers demonstrated their strength by closing the S&P 500 well below the lower-Bollinger Band (BB). As a reminder the lower-BB measures a TWO standard deviation move away from the 20-day moving average. The S&P 500 is now dangerously close to retesting its lows from the flash crash. If this line in the sand melts away then the next stop must surely be the lows from the oversold period of October, 2014: a 1820 target for the S&P 500.
