Buybacks: Value Creator or Value Destroyer?

"Repurchases only make sense when shares are available at a meaningful discount to conservatively calculated intrinsic value." — Warren Buffett

A share buyback is a company using its cash to buy back its own shares. Done well, it is one of the most tax-efficient ways to return money to owners. Done badly, it is one of the fastest ways to waste it.

The test is simple — is the share price below the company's intrinsic value?

• Below intrinsic value — the buyback reduces the share count and raises value per share. Every remaining shareholder is better off.
• Above intrinsic value — the buyback hands cash to the sellers and overpays. Management is buying its own stock expensively.

The awkward reality is that most buybacks happen when companies are flush and confident — that is, near market peaks — rather than in downturns when their shares are actually cheap. So the tool that should create value often does the opposite.

Illustrative example: same tool, opposite results

Over one decade, one large technology company bought back enormous quantities of its own stock at fair or discounted prices while earnings grew; another bought back stock at high prices while its revenues shrank. The first compounded value per share; the second did not. The mechanism was identical — the discipline about price was not.
