What is a stock buyback?

A buyback is a company repurchasing its own shares on the market: fewer shares outstanding, more earnings per share for those who remain.

It's the alternative to dividends for returning cash to shareholders: by shrinking the share count, profit is split among fewer shares and EPS mechanically rises. Apple has spent over $600 billion on buybacks in the last decade, more than any company in the world.

The debate: done at low prices they create value; done at inflated prices to prop up the stock (or management's EPS-linked bonuses) they destroy it. Buffett likes them "only when the stock trades below intrinsic value".

Concrete example

A company with 100 million shares and $1 billion in profit has an EPS of 10; after buying back 10% of its shares, the same profit becomes an EPS of 11.1: +11% without earning an extra dollar.

Frequently asked questions

Buyback or dividend?

Buybacks are more tax-efficient (no immediate tax) and flexible; dividends are discipline and tangible income. The best companies alternate both.

Are buybacks manipulation?

They've been legal and regulated since 1982; the political debate over their abuse remains open.
