A share buyback occurs when a company uses its accumulated cash reserves to purchase its own shares from the open market or directly from shareholders. These repurchased shares are either retired or held as treasury shares, reducing the total shares outstanding and increasing the ownership stake of remaining shareholders.

Key Takeaways

01.Reduces shares outstanding, which automatically inflates Earnings Per Share (EPS).
02.Signals management's confidence that the stock is undervalued.
03.Offers a tax-efficient alternative to cash dividends for returning capital to shareholders.
04.Can temporarily inflate stock price through increased buying pressure.

Why it matters

Buybacks are a key signal of capital allocation efficiency. They indicate that management believes reinvesting in their own company offers a higher risk-adjusted return than other projects or acquisitions.

Common Mistakes

Ignoring buybacks funded by debt

Companies sometimes borrow money to fund share repurchases to artificially boost EPS, which damages balance sheet health and increases financial leverage.
