The top concordant period (1985-86) is again one-week offset from last week's best concordance match, displaying a rolling alignment with recent market behavior
The concordance has strengthened, being in the "strong" concordance region in two of three metrics, and nearing strong in the third.
Given the strengthening concordance, forecasts based upon this concordance may be more reliable than for last week, though Friday's strongly down market is not adequately accounted for in the concordant period.
