Frequently Asked Questions
Which company buys back the most stock?
Apple (AAPL) is the undisputed buyback king, repurchasing approximately $94 billion in shares over the trailing 12 months — more than the next two companies combined. Alphabet (GOOGL) follows at $62 billion and Meta Platforms (META) at $48 billion. Together, these three mega-cap tech companies account for nearly 29% of all buybacks tracked in our study. Apple has been the largest buyback spender in the S&P 500 for over a decade, reducing its share count by roughly 3.8% annually.
Are stock buybacks good for investors?
Stock buybacks can be excellent for investors when executed at reasonable valuations. They reduce shares outstanding, boosting earnings per share (EPS) and each remaining share's ownership claim. However, buybacks are only value-creating when the stock is fairly or undervalued. Companies buying back stock at inflated P/E ratios effectively overpay and destroy value. The best buyback programs come from companies with strong free cash flow, manageable debt, and disciplined capital allocation. In our data, energy companies like Marathon Petroleum (MPC) achieve both high buyback yields (15.38%) and meaningful share count reductions (12.5%).
What is buyback yield?
Buyback yield measures how much of its market capitalization a company spends on share repurchases annually. Formula: (Annual Buybacks ÷ Market Cap) × 100. A 5% buyback yield means the company is repurchasing 5% of its market value in shares each year. This is analogous to dividend yield but for buybacks. The average buyback yield in our study is 2.89%. Marathon Petroleum leads at 15.38%, meaning it's aggressively shrinking its float. Combining buyback yield with dividend yield gives "total shareholder yield" — a more complete picture of capital returns.
Do buybacks increase EPS?
Yes, buybacks mechanically increase EPS by reducing the denominator (shares outstanding). If a company earns $1 billion with 100 million shares, EPS is $10. After buying back 10 million shares, the same earnings spread across 90 million shares yield $11.11 EPS — an 11.1% boost with zero change in actual profitability. In our study, Marathon Petroleum's 12.5% share reduction created roughly a 14.3% EPS boost, while Synchrony Financial's 8.5% reduction boosted EPS by approximately 9.3%. Critics call this "financial engineering" since it inflates per-share metrics without improving the business.
Are buybacks better than dividends?
Neither is universally better — they serve different purposes. Buybacks are tax-efficient (no immediate tax for shareholders), flexible (can be paused without stigma), and boost EPS. Dividends provide predictable income, signal confidence (cuts are punished by markets), and are preferred by retirees. In 2026, S&P 500 companies collectively spend more on buybacks than dividends. For total capital return, look at both together. Marathon Petroleum returns 17.16% total (15.38% buyback + 1.78% dividend), while Altria returns 8.55% (2.0% buyback + 6.55% dividend) — same concept, very different mix.
Methodology
Buyback data was compiled from SEC 10-K annual filings, quarterly earnings reports (10-Q), and the S&P Dow Jones Indices quarterly buyback reports. Buyback amounts represent trailing 12-month share repurchases as of the Q4 2025 / Q1 2026 reporting period. Market capitalization and P/E ratio data sourced from stockanalysis.com (March 2026).
Buyback yield was calculated as: (Trailing 12-Month Buyback Amount ÷ Current Market Capitalization) × 100. Share reduction percentage represents the net change in diluted shares outstanding over the trailing 12 months. EPS boost from buybacks was estimated as: Share Reduction % ÷ (100% − Share Reduction %) × 100, which captures the mechanical impact of fewer shares on per-share earnings.
Total return yield combines buyback yield with dividend yield to show the complete capital return to shareholders. Note that actual shareholder returns also depend on stock price appreciation, which is not included in this metric. Companies are selected from the S&P 500 and other large-cap U.S. stocks with significant buyback programs. Boeing (BA) is included with $0 buybacks as a reference point, as it suspended buybacks during its operational challenges.
