The Promoter Buying page lists open-market purchases by insiders of S&P 500 companies, read from their public regulatory filings. This page explains what is being read, how the list is built, and what it cannot tell you. The page itself is here, free, and updated every morning.
A list of insider purchases is not a recommendation. Nothing on the page is a suggestion to buy or sell anything. Insider buying tells you what insiders did with their own money. It never tells you why, and the why is the part that matters.
The United States has no “promoter” category. What exists instead is the Section 16 insider: officers, directors, and holders of ten percent or more of a company’s shares. They must report trades on Form 4 within two business days. That is the closest American equivalent of promoter buying disclosures Indian readers will know, and it is what this page reads.
We count only real purchases. A buy on this page is a transaction coded P on a Form 4, an open-market purchase with the insider’s own money. Option exercises, share grants, and gifts are excluded by their transaction codes, mechanically. A pre-planned sale or purchase under a 10b5-1 plan is flagged only in the filing’s footnotes, which this page does not read, so a line here can occasionally be a scheduled trade rather than a fresh decision.
What the page does not show matters. It does not show insider selling, position sizes relative to the insider’s wealth, or anything about companies outside the S&P 500. A single purchase by a director who owns almost nothing is a different fact from a purchase by a founder doubling a large holding, and the page does not weight for that.
The universe is the S&P 500 as published in the publisher’s own data export, a fixed snapshot rather than a live scrape. Each morning, an automated process reads the SEC’s daily filing index, selects every Form 4 filed by an S&P 500 company insider, and keeps the open-market purchases. The page holds the last thirty one days and a slider widens the view from one week to the full month. Companies link to StockAnalysis.com pages carrying our referral code, as disclosed in our Terms of Service.
The process is mechanical: the same filings on the same morning produce the same list. No company is added or removed by judgement, and no insider is contacted or aware of their inclusion.
The filings are public records published by the United States Securities and Exchange Commission on EDGAR and are free for anyone to read. Every line on the page comes from a specific Form 4, and anyone can pull the same documents from EDGAR and check our reading against the originals.
The SEC is not affiliated with us in any way, and nothing here is published with its knowledge or approval. No insider or company named on the page has any connection to this publication.
