Share Buybacks

🌿 Intermediate★★★★★

Share buybacks shrink the share count, boost earnings per share, and signal management confidence.

💬

When companies buy back their own shares, it's usually a good sign.

— *One Up On Wall Street*，1989

🏠 Everyday Analogy

Just as a restaurant owner uses their own money to buy shares in their own establishment, if even the owner believes the business is undervalued and is willing to invest real capital to repurchase equity, it indicates the venture holds genuine value that outsiders have overlooked.

📖 Core Interpretation

A company's stock repurchase is a signal from management that the stock price is undervalued.
💎 Key Insight：When a company buys back its own shares, each remaining share represents a larger ownership slice. This mechanically increases earnings per share even without business growth. Lynch views buybacks as a sign that management believes the stock is undervalued and that the company has no better investment opportunity. Buybacks are especially bullish when done at low valuations.

❓ Why It Matters

Share repurchases reduce the number of outstanding shares and increase earnings per share, serving as a method of returning value to shareholders.

🎯 How to Practice

Focus on the proportion of the repurchase amount relative to market capitalization and whether the repurchases are sustained.
