  • Insider buying vs selling11/20

    Insiders are sellers only: 20 sells worth $2.1M, no open-market buys, across the last 20 Form 4s. Routine executive selling is common, so this is only a mild negative. Separately, 1 new 5%+ stake disclosure (13D/13G) hit in the last 6 months, which is big-money accumulation.

All seven Magnificent Seven stocks fell today. Here's where that money actually went (July 23, 2026)

All seven Magnificent Seven stocks were red by late morning Thursday, led by Tesla's 14% drop on an earnings miss and Alphabet's close-to-7% slide despite beating estimates, on another capex raise. Amazon and Meta sold off too ahead of next week's reports. The money didn't just leave, it rotated: into defense on Lockheed's earnings beat, and out of quantum, SaaS and space.
