Insider Trading Analysis — AI Semiconductor Industry Chain Track SEC Form 4 insider trading filings from 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 required by the U.S. Securities and Exchange Commission (SEC), which corporate executives, directors, and shareholders holding over 10% of a company’s stock must submit within two business days after executing a trade. By systematically tracking these filings, you gain insight into insiders’ genuine sentiment toward their own stock—are they putting real money on the line to buy, or are they collectively offloading shares? Page Navigation Overview Get an at-a-glance view of capital flows across the entire industry chain. Key metric cards display number of transactions, total buy/sell amounts, net sell amount, and sell-pressure ratio. Below lies the real-time Filing Feed—the most practical feature: it aggregates every insider transaction from the past three days by company (collapsed by default to show only company-level summary data, e.g., net sell amount); click to expand and see full transaction details—who sold, their position, execution price, and transaction value. Group Overview Six grouped categories for horizontal comparison: Core Semiconductors (e.g., NVDA, AMD, ARM—30 companies), Optical Interconnects (e.g., ANET, ALAB—12 companies), Memory (e.g., MU), Data Center Construction (e.g., PLTR, CLS—13 companies), M7 Tech Giants, and the Full AI Semiconductor Group. Each group card displays buy/sell amounts, net amount, sell-pressure ratio, number of insiders trading, and median share reduction. Click through to view complete transaction details for that group. Comparison All groups appear side-by-side in a single table, enabling direct comparison of sell pressure, median sell amount, top 10% large-value trades (P90), and magnitude of shareholding reductions. A sell-pressure heatmap and comparative distribution chart sit at the bottom—helping you quickly identify which sector’s insiders are most actively divesting.
