SEC Insider Feed: Track U.S. Public Company Insider Trading via Real-Time API

Can you find out the moment a CEO starts aggressively selling their company’s stock? On May 20, 2026, we launched SEC Insider Feed — a real-time API service that captures insider trading data for U.S. publicly listed companies. This article explains what this API is, what it can do, and key insights we’ve uncovered using real-world data. What is insider trading data—and why does it matter? U.S. securities law requires corporate insiders—such as CEOs, CFOs, directors, and shareholders holding more than 10% of outstanding shares—to file Form 4 with the SEC within two business days after buying or selling their company’s stock. These filings are public, but they’re scattered across the SEC’s website in raw, unwieldy formats that are difficult to use directly. Insider trading activity is widely regarded as one of the strongest market signals available: ・ A CEO purchasing shares out-of-pocket → A bullish signal more reliable than any analyst report. ・ Multiple executives selling simultaneously → A collective “rats leaving the sinking ship” warning. ・ Heavy institutional减持 (e.g., by hedge funds) → An early indicator of shifting institutional confidence. The problem? These filings reside in the SEC’s EDGAR system—disorganized, fragmented, and significantly delayed. If you want to know who sold today, you might need to scroll through dozens of web pages. SEC Insider Feed solves exactly this problem. What is SEC Insider Feed?

Warning for Next Year’s Performance? U.S. Corporate Insiders’ Stock Sales Hit a Two-Decade Quarterly High

Recently, insider selling by executives at U.S.-listed companies has surged so sharply that it has drawn concern from financial media. According to a recent Financial Times report, a record number of U.S. corporate executives—from Goldman Sachs to Tesla, and even the media group owned by President-elect Donald Trump—are selling shares of their own companies, capitalizing on the post-election rally in U.S. equities. Data from VerityData shows that insider selling activity among U.S. publicly traded companies has reached its highest quarterly level in twenty years. This metric covers sales by corporate insiders—including one-off profit-taking transactions and scheduled sales triggered when share prices hit pre-set thresholds under automatic trading plans—within the Wilshire 5000 Index, one of the broadest and most comprehensive U.S. equity indices, weighted by market capitalization and covering virtually all actively traded U.S. stocks. Moreover, during Q4 of this year, the ratio of insider sellers to buyers among S&P 500 component companies stood at 23.7:1—the highest since 2004, when the U.S. first mandated public disclosure of insider trading activity. large_image?... There are many reasons why corporate insiders sell shares—and many of them have nothing to do with the company’s underlying prospects. Therefore, record-high insider selling does not necessarily signal an alarming red flag. However, given recent strong returns, elevated valuations, rising leverage, and a broadly speculative market environment, this surge in insider selling sends another cautionary signal for U.S. equities overall—suggesting that the market’s performance next year may fall short of expectations. On the relationship between insider trading and subsequent market performance, Ben Silverman, Research Director at VerityData, commented: “In general, insider selling tends to be predictive—typically foreshadowing market weakness by roughly two to three quarters.”
