Earnings Quality Analysis
Evaluate earnings quality, not just quantity.
Not all earnings are equal. Look for recurring, cash-backed earnings rather than accounting profits. High-quality earnings are predictable, sustainable, and convertible to free cash flow.
🏠 Everyday Analogy

❓ Why It Matters
Ignoring valuation turns even good companies into poor investments. Overpaying compresses future returns and leaves little margin when assumptions are wrong.
🎯 How to Practice
Estimate intrinsic value with conservative assumptions, set clear buy ranges, and act only when price offers a meaningful discount with acceptable downside.
⚠️ Common Pitfalls
Confusing a low price with true cheapness
Using one metric without business context
Overly optimistic assumptions that erase margin of safety
