S&P 500 flat as NVDA leads mega-cap Alpha; gold and bitcoin outrun the index
Reviewing Sep 14–20, 2026 · outlook and calls for Sep 21–27, 2026
The S&P 500 closed the week essentially unchanged at 761.69, while the Nasdaq-100 added 1.73% and bitcoin jumped 3.64%. NVDA carried the strongest AlphaScala profile among large caps at 73, with MSFT and AAPL trailing at 69 and 66. No politician trades or forward calendar events were disclosed for the period.
Index flat, but QQQ and crypto pulled ahead
The S&P 500 finished the week at 761.69, up 0.11% week-over-week. The Nasdaq-100 outperformed with a 1.73% gain, and bitcoin rose 3.64% to 81,034.56. Gold added 1.90% to 4,380.14.
NVDA carried the strongest AlphaScala profile among the mega caps at 73, reflecting strong momentum and quality with moderate value and sentiment. MSFT followed at 69, and AAPL at 66. Visa and JPMorgan scored 63 and 58, respectively, with both capped at 90 pending full signal ingestion.
Alpha Score dispersion among mega caps
The Alpha Score spread between NVDA and AAPL widened to 7 points this week. NVDA's 73 reflects strong momentum and quality, while AAPL's 66 combines strong momentum with poor value. The divergence suggests institutional flows favored the semiconductor leader over the consumer hardware giant during the period.
SPY itself carried an Alpha Score of 50 as of Aug. 23, with strong momentum and sentiment offset by poor value. The index-level score predates the current week and reflects only three of four signal classes.
Outlook · Sep 21–27, 2026
With no forward calendar events on file after Sept. 20, the next catalyst for S&P 500 leadership will come from the next round of AlphaScala signal updates, particularly the remaining data ingest for Visa and JPMorgan, whose scores are capped at 90 until the fourth signal class lands.
