The split became a slide: chips and the fullest multiples took the tape down

The Final Hour — Nasdaq −2.4%, S&P 500 −1.3%, Dow −0.5% into the close, as the chip complex fell for a ninth straight session and the fullest multiples led the declines. September industrial production rose 0.7% — more than double the morning’s growth line — and the 10-year yield held under 5.15% all session, yet the morning question stayed unresolved: yields never fell again and the chips never found a floor. All four Engine Picks lost their 50-day average today. The Engine List names’ into-the-close scorecard is inside.
