Latest Insider Stock Purchases & Executive Trading Activity

Every time a corporate insider — meaning an executive officer, board director, or any shareholder owning more than 10% of a company — buys or sells stock in their own company, federal law requires them to disclose it to the Securities and Exchange Commission within two business days. That disclosure is called a Form 4 filing, and it is one of the most powerful free data sources available to retail investors. Unlike analyst ratings, news headlines, or social media chatter, insider transactions show what the people actually running the company are doing with their personal money.

Open-market insider purchases are especially meaningful. Insiders sell stock for many reasons — diversification, tax planning, paying for a home, exercising expiring options — but they only buy for one reason: they believe the stock is going up. Academic research, including landmark studies by Nejat Seyhun at the University of Michigan, has repeatedly shown that stocks bought by multiple insiders on the open market tend to outperform the broader market over the following six to twelve months. When a CEO writes a personal check for a million dollars of their own company's stock, that conviction signal is hard to fake.

VonTrend's Insider Intelligence tracker filters the firehose of Form 4 filings down to the transactions that actually matter — labeled "P-Purchase" by the SEC, meaning a true open-market buy rather than an option exercise, gift, or automatic plan sale. We rank every filing by total dollar value so the multi-million dollar whale trades rise to the top, and flag any purchase that increases an insider's existing stake by more than 10% as a "Significant Increase" — the kind of conviction signal professional traders watch most closely.
