The decline over the past few days has caused some deterioration in the A/D indicators, but there are no sell signals yet. The McClellan Oscillator has reached resistance going back to the May 2007 highs, and a drop below its MA would be negative. S&P support is at 850, with a key support level at 816. Resistance is at 944 and 1000.
