Every trading day JSS emails a short list of high-conviction
picks with transparent 100-point scoring (Quality + Entry +
Sentiment + Sector). 14-year walk-forward backtests show
+163pp alpha vs S&P 500, 64% win rate. ESG/SRI filters

AND stocks missed, with losses published. No paywall, no
account. Rigor, without the black box.
