Capital allocation lessons.

1. Reinvest in the business (organic growth, capex, R&D).
2. Acquire other businesses (M&A, roll-ups, tuck-ins).
3. Pay down debt (deleveraging, refinancing).
4. Issue dividends (return cash without changing share count).
5. Buy back stock (return cash and concentrate ownership).

When the marginal return on internal reinvestment falls below the company's cost of capital, or when the stock trades meaningfully below intrinsic value. Henry Singleton (Teledyne), Katharine Graham (Washington Post), and John Malone (TCI/Liberty) repurchased aggressively only when both tests were met. Buybacks at peak valuations destroy value just as reliably as bad M&A.

• Diworsification — empire-building M&A outside the circle of competence.
• Buyback at the top — repurchasing when sentiment, not value, is the driver.
• Holding cash forever — a hidden cost of capital that compounds against shareholders.
• Dividend addiction — paying out cash that should fund organic growth at high incremental returns.
• Debt-fuelled buybacks at the top of the cycle — the fastest way to bankrupt an otherwise healthy company in a downturn.

Warren Buffett (Berkshire), Henry Singleton (Teledyne), John Malone (Liberty), Tom Murphy (Capital Cities), Katharine Graham (Washington Post), Dick Smith (General Cinema), Bill Anders (General Dynamics), Bill Stiritz (Ralston Purina). All studied each other; all dramatically outperformed the S&P over multi-decade tenures.
