The day after the wire, the tape breaks — Korea's sidecar night, dollar-yen back under 159.5, and the sovereign tell reads equity-led
Tuesday's US close did more damage to the AI build-out complex in a single session than any day since the July leg down. SOXX fell −4.96% to 531.39, XSD −5.75%, SMH −4.09%, and the DRAM ETF broke its 60 shelf outright, down −8.76% to 55.10 from 60.39 — the shelf yesterday's Pulse had it sitting exactly on did not survive the session. Fabrinet, which closed Monday at 598.58 on a clean double beat, finished Tuesday at 482.59, down −19.38% on the day — the full arc, beat, sold after hours, then sold again into the close, took roughly a fifth off the stock in 24 hours. Coherent fell −12.75%, CoreWeave −12.10%, Nebius −7.60%, Lumentum −9.87%, Applied Materials −3.92%. The tape split hard by sector rather than by size: software held or rose (IGV −0.03%, CLOU −0.47%, and the large caps were green — Salesforce +2.71%, Adobe +3.58%, Intuit +4.41%) while hyperscalers split among themselves — Apple +1.45%, Microsoft +0.27%, Alphabet +0.06% against Nvidia −2.34% and Meta −4.45%. Momentum gave back its lead outright: SPMO fell −2.75% to 150.90 while SPLV rose +0.38% to 76.03, a full reversal of Monday's momentum-led read. VIX rose +4.28% to 15.84, matching what the price action was already saying.
The day after Korea's sidecar night, the morning is calm: Europe flat, US futures flat, the 10-year easing to 4.706%, the yen firming to 159.05, Brent up a fifth straight day. Yesterday's break was equity-led on every bond instrument we watch — Treasuries bid, IGOV drifting at 41.11 rather than breaking, gold sold — unlike the sovereign-led bottoms of March and July. So the house is standing the whole bond complex up as a permanent dashboard: IGOV and its new dollar-decomposing partner GGOV, the duration-matched credit pairs, the OAS ladder, and three long-dated AI bonds whose yields kept climbing through the equity break. The instruments are monitors, not verdicts — but they are how we will know if the character of this drawdown changes.
