Trade Secrets: Dailies 10.15.2026

US Stocks open mixed with tech under heavy pressure as TSMC's best quarter in its history — revenue up 41.2% year-over-year to $46.72 billion, net income surging 68.7% to a record NT$763 billion for the sixth straight quarter, and Q4 guided to $52.3–54.3 billion — fails to reverse the AI valuation de-rating that has gripped the market all week, with TSM down 3–4% on margin dilution concerns, Nasdaq 100 futures off 1.2–1.4%, and a separate report that the US is mulling use of the "mother of all bombs" against Iran sending geopolitical risk back to the front of the tape alongside PPI, jobless claims, and retail sales all hitting at 8:30 a.m. ET.

At 2:54 a.m. ET, Dow futures were up 27 points or 0.1%, S&P 500 futures declined 38 points or 0.5%, and Nasdaq 100 futures fell 407 points or 1.4% — a continuation of Wednesday's tech selloff despite TSMC's blowout. TSM ADR was down 2.4%–4.27% in premarket to around $419–421, with the stock having already closed Wednesday at $430, down 3.4% from the prior session as investors pre-positioned defensively. Two-year Treasury yields jumped 13 basis points to 4.92% Wednesday on the hot CPI, and futures moved to roughly even odds of an October Fed hike — the highest October probability since the September FOMC minutes.
TSMC's Q3 numbers were historic in every dimension: revenue of NT$1,494.24 billion ($46.72 billion) beat the high end of its own $44.6–45.8 billion guidance and topped analyst consensus by $1.31 billion or 2.9%; net income of NT$763.06 billion surged 68.7% year-over-year; diluted EPS of $4.60 beat the $4.42 consensus by $0.18; gross margin of 66.4%, operating margin of 58.7%, and net margin of 51.1% all came in at or above guidance ranges. High-performance computing — the category that encompasses AI accelerators — surged 22% quarter-over-quarter to account for 68% of revenue, up from 57% in the same period a year earlier. The 2-nanometer node rapidly rose from 3% of wafer revenue in Q2 to 8% in Q3, and advanced technologies at 7nm and below accounted for 79% of total wafer revenue. CEO C.C. Wei said on the call that the gap between AI chip supply and demand is "still quite big" and that demand for AI infrastructure shows "no sign of a slowdown," citing agentic AI and open-source AI models as expanding demand catalysts.
The stock fell anyway — because the market is focused on what comes next rather than what already happened. The 2-nanometer ramp and overseas fab expansion in Arizona pulled gross margin down 130 basis points from Q2's 67.7%, and management guided Q4 gross margin at approximately 57%, another step down from Q3's 66.4%. Full-year 2026 revenue growth guidance was raised to approximately 44% — up from the previous "slightly above 40%" — but that upside was already partially priced in after the strong monthly revenue pre-release. The WallStreetPlumber summed up the tape: "TSMC printed its best quarter ever this morning. The stock is down anyway. Both facts are the story." UBS kept TSMC as a top pick and said the guidance raise could support higher 2027–28 targets, but margin compression during a technology node ramp is a well-established pattern that creates near-term valuation pressure even when the long-term thesis is intact.
The AI valuation de-rating has now consumed four of the past five trading sessions. Anthropic reported strong revenue growth — full details not disclosed publicly but described as strong by sources in the premarket — yet even that failed to reverse the AI sentiment pressure. The Broadcom CEO separately highlighted concerns about AI buildout financing this week, adding a CFO-level voice to the AI capex sustainability debate that Burry, the Goldman Sachs research, and the OpenAI revenue shortfall have been feeding for weeks. AI-adjacent cloud infrastructure names including CRWV, NBIS, IREN, and HUT were all under pressure for a second session.
PPI, retail sales, jobless claims for the week ending October 10, the Empire State and Philly Fed manufacturing indexes all print at 8:30 a.m. ET — a dense data morning that could move October rate hike odds further in either direction after Wednesday's CPI pushed them to roughly 50%. Fed's Michelle Bowman and Beth Hammack are both scheduled to speak today. Charles Schwab (SCHW) and Alcoa (AA) are the session's notable earnings. Domino's Pizza (DPZ) was on the week's original calendar, alongside Schwab.
The US is reportedly mulling the use of the GBU-43/B Massive Ordnance Air Blast — the "mother of all bombs" — to target Iran's deeply fortified underground nuclear sites, per Newsquawk citing multiple sources. The report, which the Pentagon has not confirmed, represents the most specific military targeting discussion to emerge publicly since Trump pledged no strikes before the November 3 midterms and further reinforces the two-sided risk from the Iran conflict: any strike before November 3 would be a complete reversal of Trump's public pledge. Iran fortified its nuclear sites following reports of planned post-midterm strikes, and the Houthi threat to Saudi infrastructure remains active following last weekend's claimed Riyadh airport attack.
Asian markets were broadly lower. Japan's Nikkei 225 fell on a second straight session of chip-equipment weakness, with Advantest and Tokyo Electron both down as the TSMC sell-the-news reaction filtered into Japan's most AI-sensitive names. South Korea's KOSPI fell further, with Samsung and SK Hynix extending their multi-session declines as the memory chip segment was "getting hit" per multiple premarket notes. The Taiwan TAIEX was sharply lower as TSM fell in Taipei trading before the US market open. China's CSI 300, Hong Kong's Hang Seng, and Australia's ASX 200 all edged lower as the combined weight of the CPI shock, AI valuation pressure, and Iran escalation reports kept risk appetite suppressed across the region.
