Utilities and health care lead as communication services slumps

Last week's trading produced one of the sharpest sector splits of the year: defensive and value groups such as Utilities (+3.31%), Health Care (+2.98%), Energy (+2.89%) and Real Estate (+2.81%) rallied even as Communication Services collapsed 5.10% and Information Technology slipped 0.95%, dragging the S&P 500 down 0.47% and the Nasdaq-100 down 1.63%. The split traces largely to megacap earnings: a post-report slide in large communication-services names weighed on that sector, while investors rotated into groups seen as insulated from AI-spending anxiety. Financials were the week's quiet standout, up 2.05%, helped by strong beats from First Citizens BancShares (FCNCA) and American Express (AXP).

This week decides whether that rotation holds or reverses. The Federal Reserve's rate decision on Wednesday, October 28, and the September personal consumption expenditures inflation report on Thursday, October 29, are the macro anchors, arriving as investors weigh whether slowing growth or sticky inflation is the bigger risk. Layered on top is one of the heaviest stretches of megacap earnings this year: Alphabet and Microsoft report Wednesday, Amazon reports Thursday, and each will offer guidance on AI infrastructure spending that last week's selloff in tech and communication-services names suggests the market is no longer taking for granted. Energy earnings cluster Friday with ExxonMobil, Chevron and BP, testing whether crude's 9.9% monthly gain is actually showing up in results despite its 2.0% weekly dip. With Visa, Coca-Cola and Boeing reporting Tuesday, and Caterpillar and Intel on Thursday, the week offers a broad cross-section of consumer, industrial and tech health just as the Fed delivers its verdict.

Last week's sector leaderboard looked almost purely defensive: Utilities, Health Care, Energy and Real Estate all gained more than 2.8% while Communication Services fell 5.10% and Technology slipped 0.95%. The proximate cause was megacap earnings rather than a broad macro shift: our catalyst radar had flagged unusual option volume and trump disclosed-purchase watchlist activity around Meta (META) and Alphabet (GOOGL) ahead of their reports, and the subsequent pullback in communication-services names dragged the sector lower, while Financials quietly outperformed on beats from First Citizens BancShares (FCNCA, +16.8% EPS surprise) and American Express (AXP, +3.3%). This week's megacap slate, Alphabet (GOOGL) and Microsoft (MSFT) on Wednesday and Amazon (AMZN) on Thursday, will determine whether the rotation out of high-multiple tech extends or reverses. A guidance beat on AI infrastructure spending could pull momentum back toward growth names; a cautious tone would likely reinforce the move into value and defensives that dominated last week's tape, with Visa (V) and S&P Global (SPGI) reporting Tuesday as additional financials reads.

Our catalyst radar flagged unusual option activity and hyperscaler-linked signals across CoreWeave (CRWV), Super Micro Computer (SMCI), Novanta (NVTS) and Credo Technology (CRDO) last week, all tied to the AI data-center buildout theme. Communication Services' 5.10% drop and Technology's 0.95% slide suggest the market is starting to price in more scrutiny of that spending rather than treating it as unconditional good news. This week's megacap earnings, Microsoft and Alphabet on Wednesday and Amazon on Thursday, are the real test: all three are among the largest buyers of AI infrastructure, and their capital-expenditure guidance will move the entire supply chain, including memory maker Micron (MU), which our radar also flagged for unusual options and congressional trading activity. A guidance miss or a cautious capex tone from any of the three hyperscalers would likely extend pressure on the smaller AI infrastructure names; reaffirmed spending plans would support the group heading into November.

Gold and silver booked some of the sharpest pullbacks across any asset class, with gold down 3.6% on the week and 7.2% over the month, and silver down 6.1% weekly and 16.7% monthly, consistent with profit-taking after an extended run. Crude oil told a different story: WTI slipped 2.0% on the week but is still up 9.9% over the month, and Energy was last week's third-best sector at +2.89%. That divergence sets up Friday's energy earnings cluster of ExxonMobil (XOM), Chevron (CVX) and BP as a key read on whether the month's crude strength is actually reaching the bottom line, or whether producers are still absorbing softer spot prices. Southern Copper (SCCO), reporting Monday, offers an early look at industrial-metals demand after copper's milder 0.2% weekly and 2.5% monthly declines, which have held up better than the metals complex overall.

The macro calendar centers on the Federal Reserve's two-day meeting, with the rate decision due Wednesday, October 28, followed by the September personal consumption expenditures inflation report, the Fed's preferred inflation gauge, on Thursday, October 29. Earnings flow heavily all week: Verizon, Cadence Design Systems and Public Storage report Monday; Visa, Coca-Cola, Boeing and S&P Global follow Tuesday; Alphabet, Microsoft, T-Mobile and KLA report Wednesday alongside the Fed decision; Amazon, Eli Lilly, Mastercard, Caterpillar, Merck and Intel report Thursday; and the week closes Friday with ExxonMobil, Chevron, BP, AstraZeneca and AbbVie. With hundreds of companies in our tracked universe reporting this week, the Wednesday-Thursday stretch carries the most weight for market direction given Alphabet, Microsoft and Amazon's combined influence on index-level moves.
