By AlphaScala Research DeskPublished Reviewing Oct 26 – Nov 1, 2026 · outlook and calls for Nov 2–8, 2026
Price data for SPX stopped updating on Sep 5, 2026, before the week this briefing reviews. Price levels quoted below for it may be out of date.
The S&P 500 fell 1.26% for the week, a decline that paled next to the Nasdaq-100's 3.04% drop. Rep. Pete Sessions (R-TX) disclosed sales of MSFT, AAPL, NVDA, and V totaling roughly $1.1 million, concentrated on a single day in early October. The disclosures, combined with weak momentum scores on several mega-cap names, left the index's leadership looking narrow.
Tech Drags the Tape Lower
The S&P 500 dropped 1.26% to 755.71, but the headline masked a sharp divide. The tech-heavy QQQ tumbled 3.04%, its worst week relative to the broader market in over a month. Gold added 0.66% on the session to trade near $3,901, while bitcoin was flat at $78,297.
Energy and financials cushioned the blow. XOM carried an Alpha Score of 62, the highest in the cohort, with a reading that flagged strong momentum. JPM sat at 60, the only name in the group with a moderate reading across all four signal pillars.
Sessions Unloads Tech
The heaviest political flow of the week came from a single member. Rep. Pete Sessions (R-TX) filed five sales on October 2, disclosed during the period, that cut his exposure to MSFT, AAPL, NVDA, V, and XOM.
The two largest transactions were in MSFT and AAPL, each in the $250,000 to $500,000 range. He also sold a smaller stake in NVDA, between $15,000 and $50,000. Across the five filings, the total value landed between roughly $530,000 and $1.1 million.
Sessions was not alone. Rep. David J. Taylor (R-OH) disclosed a sale of Visa on October 15, valued at $1,000 to $15,000. The two Visa sales landed against an Alpha Score of 56 for the stock, which showed strong momentum but poor value.
Alpha Scores Show a Split Market
The Alpha Score leaderboard for the week's most-traded names revealed a market leaning on old-economy strength. XOM's 62 was the high-water mark, driven by momentum. MSFT and JPM each posted a 60, though the composition differed: MSFT carried strong momentum and strong quality against poor value, while JPM was moderate across the board.
BRK.B sat at 59 with weak momentum but strong value. NVDA, at 57, shared MSFT's strong-quality, poor-value profile but with only moderate momentum. The pattern suggested a market rewarding near-term price trends in energy and financials while punishing the valuation premiums still embedded in large-cap tech.
No insider clusters fired on any S&P 500 constituent during the week, leaving the political disclosures as the only visible smart-money signal.
Outlook · Nov 2–8, 2026
The disclosures from Sessions are backward-looking, but the concentration in a single day's trading and the size of the MSFT and AAPL sales will draw attention if other members file similar tech reductions in the next reporting window. With no high-impact events on the immediate calendar, the next catalyst is the flow of fresh PTR filings.
