Market Summary

U.S. equities closed broadly lower on Friday, October 23, capping a volatile week dominated by shifting AI-trade sentiment. The Dow Jones Industrial Average led the decline, falling 652.82 points (-1.23%) to 52215.37, while the S&P 500 shed 39.75 points (-0.52%) to close at 7623.75 and the Nasdaq Composite slipped a more modest 53.52 points (-0.21%) to 25975.78. The headline index losses masked considerably weaker breadth beneath the surface — the equal-weighted S&P 500 fell 0.8% on the day, underscoring that declines were broad-based rather than concentrated in a handful of mega-caps.

Surging crude oil prices were the dominant macro driver, with WTI crude settling $3.72 higher (+3.7%) at $103.17/bbl on renewed U.S.-Iran escalation concerns, reigniting inflation worries just as Treasury yields ticked higher across the curve. Sector rotation remained a defining theme of the week: Energy (+2.5% Friday) and Information Technology (+0.4%) were the only sectors with meaningful gains outside Real Estate (+0.2%), while Consumer Staples (-1.8%), Communication Services (-1.4%), and Consumer Discretionary (-1.4%) led the laggards. Within tech, software continued to decouple from semiconductors — the IGV software ETF rose 1.7% on the day (and 6.0% for the week) while the PHLX Semiconductor Index recovered only a fraction (+0.4%) of Thursday’s brutal 6.7% drop.

For the week, results were mixed: the S&P 500 fell 0.5% and Nasdaq fell 0.7%, while the DJIA gained 0.4% and the small-cap Russell 2000 outperformed with a 2.0% advance. WaveFinder breadth data confirms the cautious underlying tone heading into the new week, with Primary Sentiment reading Bearish (789 bulls vs. 1,520 bears) even as the longer-term 40-day SMA sentiment remains Bullish — a classic sign of a market digesting gains rather than breaking down structurally. Only 34% of stocks sit above their 20-day moving average and 43.4% above their 40-day moving average, pointing to narrow near-term leadership. Earnings season accelerates further next week with Amazon, Microsoft, and Alphabet all set to report, likely determining whether AI-infrastructure skepticism persists or eases.

Stock Spotlight

Comfort Systems (FIX) delivered one of the most dramatic earnings disconnects of the session, plunging 9.33% to $1,159.99 despite posting exceptional Q3 results. EPS surged 68.6% yr/yr to $13.91 and revenue jumped 53.7% to $3.77 bln, driven by technology/data-center construction demand. Technology customers now represent 60.8% of total revenue (up from 45.8% a year ago) and accounted for nearly 90% of the quarter’s revenue growth. Backlog surged 90.0% yr/yr to a record $17.81 bln, with same-store backlog nearly doubling to $17.39 bln from $9.38 bln. Operating margin expanded 110 bps yr/yr to 16.6%, though gross margin was flat at 24.8% and slipped 110 bps sequentially.

The stock’s negative reaction — its second consecutive post-earnings decline despite strong fundamentals — highlights how deeply FIX has become tied to the AI infrastructure investment cycle, and how vulnerable that linkage has made the stock to broader skepticism about the sustainability of AI-related capital spending. Management expects supportive conditions to continue through 2027, but investors are evidently discounting the durability of that growth trajectory given elevated starting valuations. A similar dynamic played out at American Express (AXP), down 3.68% to $313.20, where a slight revenue miss ($20.06 bln vs. $20.12 bln expected) and rising customer-benefit expenses (+16% to $8.89 bln) overshadowed a 13% EPS beat and a raised FY26 guidance floor ($17.60–$17.90), reinforcing a session-wide pattern of “good-but-not-perfect” results being punished.

Bond Market & Treasuries

Treasuries retreated Friday after Thursday’s sharp rally, though the complex still notched a third consecutive weekly gain. The 10-year note yield rose 4 bps to 4.988–4.99% (down 11 bps for the week), pushing just past its 50-day moving average (4.984%) ahead of a data-heavy week. The 2-year yield rose 4 bps to 4.68% (-6 bps week), the 3-year rose 4 bps to 4.75% (-8 bps week), the 5-year rose 4 bps to 4.81% (-9 bps week), and the 30-year rose 3 bps to 5.32% (-12 bps week).

Key drivers included the persistent rise in oil prices above $103/bbl, ongoing AI-trade financing concerns, and anticipation of Moody’s sovereign ratings review of France (expected to follow S&P and Fitch downgrades). The U.S. Dollar Index rose 0.2% to 101.81, roughly flat for the week. EUR/USD fell 0.2% to 1.1193, GBP/USD fell 0.2% to 1.3372, and USD/JPY rose 0.1% to 156.88.
