Equities head into the first full week of November on the back foot. The S&P 500 closed Friday at 7,580.07, down 1.82%, and the Nasdaq Composite dropped 2.86% to 25,437.00. Selling centered squarely on semiconductors. AMD plunged 10.88%, AVGO fell 5.48% and NVDA lost 4.22%, dragging the Technology sector down 6.2%. The Dow (-1.09%) held up better thanks to its lighter chip weighting. Breadth was not as poor as the indices imply: six of 11 sectors finished higher, pointing to rotation rather than wholesale de-risking. Mega-cap platforms held in comparatively well, with MSFT -1.55%, AAPL -1.23% and AMZN -1.41%. That suggests the selling targeted the high-beta AI hardware complex specifically rather than growth broadly.
The beneficiaries were the market's traditional shelters. Consumer Staples rose 1.79% (WMT +1.86%, COST +1.63%, KO +1.36%), and Utilities added 1.08% (NEE +1.91%, D +2.30%). In Health Care, pharma (LLY +3.19%, MRK +2.18%) offset weakness in UNH. Energy was the top sector at +2.09% as WTI climbed 2.08% to $104.12, with refiners VLO (+3.92%) and MPC (+2.83%) leading. Prediction markets help explain the oil bid. Polymarket odds of the US-Iran ceasefire holding through November 30 sit at just 37%, versus 99% for October 31, and only 26% expect a US announcement ending the Iranian blockade by month-end. Gold, by contrast, fell 3.29% to $3,898.90, which sank miners NEM (-4.64%) and FCX (-5.55%). Notably, gold has been trading with the NQ intraday (rolling correlation +0.44), so it is behaving more like a liquidity asset than a haven.
The macro backdrop offers little relief for multiples. Polymarket assigns a 97% probability to no Fed rate cuts in 2026. The inflation data explain why: September headline CPI ran 3.7% y/y, PPI 6.3% y/y, and the ISM Manufacturing prices component is expected at 77. Meanwhile, the Atlanta Fed's GDPNow tracker at 3.3% shows growth holding up. That stagflation-tinged mix of firm activity and sticky prices makes rate relief unlikely, and long-duration semiconductors are the most exposed. Overseas, the Nikkei slid 2.12% in sympathy with chips and the DAX fell 0.85%, while the Hang Seng bucked the trend with a 1.46% gain.
Positioning raises the stakes. SPY gamma exposure has been negative for 13 consecutive sessions at roughly -$11.3B per 1% move, and the index now sits below the 774 zero-gamma flip. The 750 put wall, equivalent to about 7,500 on the S&P 500, is the next meaningful support, with the 800 call wall well overhead. SPY ATM implied volatility of 15.4% ranks in the 73rd percentile of its range. The nearest-expiry implied move of just ±0.9% looks light given Friday's realized move and the event calendar. One curiosity: 25-delta skew of -2.5% shows calls being bid, so some traders are positioning for a short-covering snapback that negative gamma could also accelerate.
The week ahead is dense. Monday brings ISM Manufacturing (consensus 54.6, with the prices component at 77), followed by Fed Governor Goolsbee's remarks and the Treasury's refunding financing estimates. Tuesday's midterm elections add a political variable alongside JOLTS (7.13M expected). Wednesday is the key session for rates, with the Treasury refunding announcement, ADP (65K expected) and ISM Services, whose prices component is seen at 75. Friday's October payrolls report (consensus 65K vs. 29K prior, unemployment 4.2%) caps the week ahead of the November 10 CPI. With the S&P below its gamma flip and crude above $100, the burden of proof is on the bulls. A defensive tilt toward Staples, Utilities and Energy remains the path of least resistance until semiconductors find a floor.
