Re. the summation index, I have done some reading up on this so I get a better understanding of it. At its core it is best on Net Advances.

The one you posted, based on the NYSE, looks quite healthy.

I have also looked at the NASDAQ one, which unless i'm looking at this wrong, is showing a negative divergence. Check the chart linked below where the summation index sinks to new lows yet the NASDAQ index holds up an consolidates. The market breadth isn't confirming the price of the index.

Yep, the Nasdaq breadth continues to be very weak which i highlighted earlier in the week http://stageanalysis.net/forum/showthrea...71#pid4271 and the Nasdaq McClellan Oscillator and Summation Index is highlighting that fact. Somethings got to give soon, either the NYSE will follow the Nasdaq lower or the Nasdaq will recover. Interesting times...
