Stocks gave back a full point of gains into the bell as the bond market, not the data, ran the show.
The tape had every reason to rip: August PCE printed 0.3% m/m with the Fed's preferred core gauge cooling to 3% y/y, and ADP smashed estimates at 90k versus 68k consensus. The S&P ran up nearly 0.7% and Nasdaq almost 1% on the print, led by mega-cap tech and communication services. Then the 10-year Treasury yield ripped through prior highs to 5.30%, its highest level since 2002, with the 30-year touching 5.65%, and equities faded hard into the close, the S&P finishing down 0.25% at 7,651.54 while the Dow dropped 0.86%. Nasdaq alone held a green close.
Leadership was narrow and defensive underneath the index-level noise: comm services and utilities carried the early tape, financials and consumer discretionary lagged all day. Breadth was the real story — new 52-week lows swamped new highs by roughly 11-to-1, and decliners beat advancers by a wide margin even as headline indices flirted with gains. That divergence into a losing September (S&P -0.5%, Dow -4.3%) leaves dealer positioning fragile heading into month-end unwind flows.
The risk: Thursday's ISM manufacturing print and jobless claims set the tone before Friday's September payrolls report, the real swing factor for whether 5.30% on the 10-year holds or breaks toward 5.5%. Micron's after-hours print is the overnight wildcard for AI-capex sentiment — a miss compounds the yield-driven de-rating in richly-valued tech.
