Nasdaq 100 Stocks SEC Filings — September 30, 2026
The 7 filings for the NASDAQ-100 stream, all dated September 30, 2026, reveal a bifurcated market landscape. Micron Technology's record fiscal 2026 results, with revenue surging 256% YoY to $133.19 billion and gross margins expanding to 80.7% from 39.8%, underscore the massive AI-driven demand for memory, though guidance for a sequential revenue decline in Q1 2027 signals a potential near-term digestion phase. In contrast, insider activity across Costco and Meta shows consistent selling by top executives, with Costco's EVP and SEVP each selling at $915.93 and Meta's COO executing multiple sales under a 10b5-1 plan, suggesting a cautious stance on valuation. Qualcomm's director stock awards are routine, while Strategy Inc's DEFA14A filing is purely administrative. The overarching theme is a market rewarding fundamental growth (Micron) but with rising insider caution at high valuations, creating a nuanced risk-on/risk-off dynamic. The key portfolio-level pattern is the divergence between operational strength in AI-adjacent hardware and the defensive, profit-taking behavior of insiders in consumer and social media names.
