Top insider purchases this week

These are the stocks with the most significant insider buying on the open market — ranked by what's worth following: the dollars, how big the buying is next to the company's value, how unusual it is for that stock, who bought (a CEO or director counts more than a fund) and how many insiders bought separately. Filings sent in late (Form 4 is due within two business days), group purchases at one price (an offering or a directors' plan), fresh IPOs, stocks under $1–2, tiny companies and stocks in a long slide all rank lower. Only discretionary open-market purchases count: no stock awards, option exercises or pre-scheduled Rule 10b5-1 trades. Buying and selling are ranked separately: where executives bought while a fund sold, the buying is listed here and the fund's sale on the selling list. The amount is what those insiders bought, after subtracting anything the same person sold.

Why insider buying matters

Insiders sell for many reasons — taxes, diversification, a new house — but they usually buy for one: they expect the shares to rise. Research going back decades has found that stocks with heavy insider purchases, especially cluster buys by several insiders at once, have tended to outperform. Purchases that are large relative to the company's market value are the most meaningful, which is why the % of market cap column matters as much as the dollar amount.
