PowerStocks Research has launched a JSE Advance/Decline Summation Index together with weekly charts that track Advance/Decline ratios and Decline/Advance ratios. These are important indicators for investors and market timers but nobody in SA publishes them for the JSE. We have posted new research "Profiting from Advance/Decline ratios" that demonstrates the usefulness of these indicators.

Apart from their usefulness in identifying market bottoms, peaks and "special situations", we need the historic and ongoing Advance/Decline data for the JSE as a precursor to establishing yet another South African first, namely the creation, maintenance and publication of the first ever "McLellan Summation Index" for the JSE.
