Insider Trading Analysis — AI Semiconductor Supply Chain Track SEC Form 4 insider trading filings across 53 core AI semiconductor companies. Data sourced from the SEC EDGAR database, refreshed every 5 minutes — so you’re among the first to know what insiders are buying or selling. What can this tool do for you? Form 4 filings are mandatory public disclosures that corporate executives, directors, and shareholders holding ≥10% of a company’s stock must submit to the U.S. Securities and Exchange Commission within two business days of any transaction. By systematically tracking these filings, you gain insight into insiders’ genuine sentiment toward their own stock — whether they’re putting real money on the line to buy, or executing coordinated sell-offs. Page Navigation Overview At a glance, see capital flow across the entire supply chain. Key metric cards display number of transactions, buy/sell amounts, net selling, and sell-pressure ratio. Below, the real-time Filing Stream is the most practical feature: every insider trade over the past three days is grouped by company (collapsed by default), showing only aggregated company-level data (e.g., net sell amount). Click to expand and view full details per transaction: who sold/bought, their title, execution price, and transaction value. Group Overview Six horizontal group comparisons: Core Semiconductors (30 companies including NVDA, AMD, ARM), Optical Interconnects (12 companies including ANET, ALAB), Memory (e.g., MU), Data Center Infrastructure (13 companies including PLTR, CLS), M7 Tech Giants, and the full AI Semiconductor cohort. Each group card displays buy/sell amounts, net value, sell-pressure ratio, number of insiders trading, and median reduction in holdings; click through to see complete transaction details for that group. Comparison All groups displayed side-by-side in a single table — enabling direct comparison of sell pressure, median sell size, top 10% large-value trades (P90), and magnitude of holdings reduction. At the bottom: a sell-pressure heatmap and comparative distribution chart of holdings reduction — helping you quickly identify which sector’s insiders are most aggressively offloading shares.
