Measures: Tau = 0.613266, Gini = 0.891512 and Rho = 0.817545 Concordant+Predictor Period: S&P (3/11/2013 to 1/14/2015), Most Recent 200 Market Days: S&P (4/1/2016 to 1/13/2017), Forecast: S&P (from 1/17/2017 to 2/6/2017)
The top concordant period again shifts to a different year-range. All three metrics declined, with GMD dropping below the strong range, and both Tau and Rho declining more than 0.04.
Given this weakening, along with the shift to a wholly different year-range, forecasts based upon this concordance likely be less reliable than the previous week's.
