Margin of Safety in Valuation

🌿 Intermediate★★★★★

Buy at significant discounts to intrinsic value. 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 Margin of Safety in Valuation, 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: Margin of safety is the cornerstone of value investing.
