🏠 Everyday Analogy

Just as assessing a person's physical fitness isn't solely about how fast they run today, but rather whether their weight has increased reasonably and their muscles have grown stronger over the past decade, the same principle applies to a company's earnings per share. If it grows by at least 33% over ten years, it indicates that the company resembles a healthy, growing individual—possessing sustainable profitability.

📖 Core Interpretation

Over the past decade, earnings per share have grown by at least one-third.
💎 Key Insight：This growth requirement ensures you are not buying a stagnant or declining business. A one-third increase over a decade translates to roughly 3% annual growth, a modest bar that filters out deteriorating companies while remaining achievable for solid enterprises. It confirms minimum vitality without demanding speculative growth rates.
