What a Buyback Is
When a company buys back its own shares on the open market, those shares are retired (removed from circulation). Fewer shares outstanding means each remaining share represents a larger piece of the company.
Example: A company has 1,000 shares and earns $10,000. - EPS = $10,000 / 1,000 = $10 per share - Company buys back 100 shares → 900 shares remaining - EPS = $10,000 / 900 = $11.11 per share - Your EPS increased 11% without the company earning a single extra dollar
Why Companies Do Buybacks
- **Boost EPS:** The math above. Fewer shares = higher earnings per share.
- **Return cash to shareholders:** An alternative to dividends (more tax-efficient for investors in many cases).
- **Signal confidence:** "We think our stock is undervalued, so we're buying it ourselves."
- **Offset dilution:** Cancel out shares issued through employee stock options.
The Bull Case
- Tax-efficient way to return capital (vs. dividends which are taxed immediately)
- Flexible — company can stop buybacks if business conditions deteriorate
- Increases your ownership percentage of the company
- The biggest buyers in the stock market are the companies themselves
The Bear Case
- Companies often buy back stock at the worst time (near highs when they feel flush with cash)
- Can be used to artificially inflate EPS to hit executive bonus targets
- Money spent on buybacks could be invested in R&D, hiring, or acquisitions
- Doesn't create real economic value — just financial engineering
How to Evaluate a Buyback
A buyback is good when: - The stock is trading below intrinsic value (company is buying cheap) - The company has excess cash after investing in growth - Share count is actually decreasing year over year
A buyback is bad when: - The company is borrowing money to buy back stock - The stock is at all-time highs (buying expensive) - Share count isn't decreasing (buybacks just offset employee stock dilution)
Check the 10-K filing for "shares outstanding" over 3-5 years. If it's not declining despite billions in buybacks, the company is just treading water.
