Weekly commentary
2026-W39 — Semiconductor insider activity totaled about $317.6M in sales: NVIDIA director Mark Stevens ($300.1M, the only non-plan filing of the week), NVIDIA CFO Colette Kress ($7.6M), NVIDIA general counsel Timothy Teter ($6.8M), AMD EVP Forrest Norrod ($8.7M), and Arm CFO Jason Child ($3.1M). No purchases, no 13D filings, and no institutional accumulation anywhere in the sector.
2026-W38 — AMD's Lisa Su filed the sole semiconductor transaction this week, a $48.1M standing-plan sale — the largest dollar total of any sector and any single filing this week. No purchases, no 13D filings, and no institutional accumulation anywhere in the sector.
2026-W37 — Semiconductor insider activity this week totaled about $235.6M in sales, entirely NVIDIA director Mark Stevens's non-plan trust disposal — his second consecutive week of discretionary selling at this scale. No purchases, no 13D filings, and no institutional accumulation anywhere in the sector.
2026-W36 — Semiconductor insider activity this week totaled about $427.1M in sales, almost entirely NVIDIA director Mark Stevens's $410.8M non-plan disposal, alongside smaller standing-plan sales from NVIDIA's general counsel ($6.5M), AMD's CFO ($7.1M), and Arm's CFO ($2.7M). No purchases, no 13D filings, and no institutional accumulation anywhere in the sector.
2026-W35 — All semiconductor activity this week was AMD insider selling: CEO Lisa Su, CTO Mark Papermaster, EVP Forrest Norrod, and general counsel Ava Hahn together filed about $30.2M in 10b5-1 plan sales, the largest dollar total of any sector this week. No purchases, no 13D filings, and no institutional accumulation anywhere in the sector.
2026-W34 — The Q2 13F season shows broad, if uneven, accumulation across the chip stack: Micron drew a roughly 16x increase from Coatue, TSMC picked up net adds from three of four holders, and Applied Materials/Lam Research split between a clean add and a mixed picture. Broadcom is the clearest divergence — one manager doubling down while another exited entirely.
2026-W30 — One seller, one name: AMD's CTO on a standing 10b5-1 plan (~$3.3M). No buys, no activist filings, no 13F adds in chips this week.
2026-W29 — Two sellers, two names. The NVIDIA director's ~$186M discretionary trust sale dominates the dollar figure; AMD's CTO sale was a small scheduled disposal. No accumulation, no activist filings, no 13F adds in chips this week.
