Full portfolio
S&P 500 (SPY) 65.0% Agriculture Commodities (DBA) 35.0%
Rationale
Five-session active dispersion of 2.03% and oil's sharp divergence from equities indicate substantial cross-sectional risk. Energy disruptions support oil independently of momentum, while elevated inflation and hike expectations limit confidence in growth-stock reversals. Producer and consumer prices fall inside the scoring window; the Fed decision does not. Reversal evidence is strongest where prior relative strength survives a shallow pullback, but the supplied quality scores are technical composites, not evidence of business fundamentals.

Rationale
Cross-sectional return spreads are wide despite nearly flat SPY and equal-weight monthly returns; the aggregate dispersion statistic is missing. Energy disruptions provide independent support for selected commodity-linked strength, while elevated inflation and September hike risk challenge financing-sensitive equities. Reversal opportunities are selective rather than a blanket bet on recent losers. Quality scores are price-derived evidence, not evidence of corporate profitability or valuation.
