Cannibal Stocks

Companies that eat their own shares: the diluted share count fell by 3% or more over three fiscal years. The question that matters is whether the people running them are buying too.

This list will appear after the next update of company financial statements.

Why the share count matters

When a company buys back more stock than it hands out as pay, each remaining share owns a bigger slice of the business. Over years this adds up: a company that cuts its share count by 5% a year grows earnings per share by about 5% a year with no growth at all.

A buyback is only as good as the price paid. A company buying while its own insiders sell heavily is spending shareholders' money at a price the insiders seem happy to take. Buying alongside insiders is the stronger combination.

Share count is the weighted average diluted share count from each annual report's XBRL data, adjusted for stock splits. Insider amounts are open-market purchases and sales reported on Form 4. See also buybacks versus insider selling. Not investment advice.
