Bottom-Up Value Analysis

🌿 Intermediate★★★★☆

Analyze each investment individually on its merits. Ignoring valuation turns even good companies into poor investments. Overpaying compresses future returns and leaves little margin when assumptions are wrong. Estimate intrinsic value with conservative assumptions, set clear buy ranges, and act only when price offers a meaningful discount with acceptable downside. In Bottom-Up Value Analysis, Seth Klarman focuses on the gap between price and value. Returns come from paying less than what a business is worth, not from guessing short-term market moves. Key insight: Bottom-up analysis finds value that top-down misses.

Avoid misuse: Confusing a low price with true cheapness
