SPY edges up 0.48% as QQQ slips; MSFT, NVDA Alpha Scores top 70
Reviewing Oct 5–11, 2026 · outlook and calls for Oct 12–18, 2026
The S&P 500 ticked 0.48% higher this week while the Nasdaq-100 fell 0.65%, a divergence that left the index flat but masked a rotation out of tech. Microsoft and Nvidia held Alpha Scores of 73 and 71, the strongest among megacaps, even as the broader group drifted. With no high-impact events on the calendar, the week ahead hinges on whether the QQQ underperformance persists.
The S&P 500 closed the week at 778.57, a gain of 0.48% that barely registered against a 0.65% drop in the Nasdaq-100. The split was the week's defining feature: defensive and value-oriented names held the index steady while tech, the engine of the prior rally, lost ground.
No single catalyst drove the rotation. Volumes were light, and the economic calendar was empty of major releases. The move felt more like position-squaring than a fundamental reassessment. Gold and bitcoin were essentially flat on the session, offering no cross-asset signal.
Alpha Scores for the six largest names in the index painted a mixed picture. Microsoft and Nvidia remained in strong territory, while Apple and JPMorgan sat in the moderate range. The scores reflect momentum and quality metrics that have not yet rolled over, even as price action stalled.
| Ticker | Alpha Score | Profile |
|---|---|---|
| MSFT | 73 | Strong momentum, strong quality |
| NVDA | 71 | Strong momentum, strong quality |
| BRK.B | 61 | Strong value, moderate quality |
| AAPL | 58 | Strong momentum, poor value |
| V | 55 | Moderate value, strong quality |
| JPM | 54 | Moderate value, moderate quality |
A single political trade hit the tape during the period. Representative Lloyd Doggett disclosed a purchase of Johnson & Johnson worth between $1,000 and $15,000 on September 8. The transaction was small and isolated, providing no cluster signal. JNJ does not appear in the Alpha Score table, and the trade alone does not shift the sector narrative.
Outlook · Oct 12–18, 2026
The index enters a week with no scheduled high-impact events, leaving the QQQ-SPY divergence as the main dynamic to watch. Microsoft's Alpha Score of 73 is the highest among the megacaps, suggesting the momentum factor is still concentrated in a handful of names. If tech continues to bleed, the S&P 500's ability to hold its recent range will depend on whether value and defensives can pick up the slack.
