Walter Schloss
Graham's most faithful disciple: achieving 47 years of compounding miracles with pure low-price asset strategy
Walter Schloss studied under Benjamin Graham and worked as an analyst at Graham-Newman. After leaving in 1955, he founded Walter J. Schloss and Associates and later managed money with his son Edwin. Archival materials show a method centered on discounts of price to value, balance-sheet analysis, broad diversification, and independent judgment. His fund closed in 2000 and he stopped actively managing outside money in 2003; the archive summarizes long-run annualized returns of about 15.3% versus about 10% for the S&P 500.
Methodologies
- 16 Value Investing Principles - Schloss distilled 40 years of investment experience into 16 simple and actionable principles covering stock selection, position management, and psychological management.
- Net Asset Value Discount Buying Framework - Systematic net asset value discount screening and buying process, using asset liquidation value as the safety floor.
Key decisions and timeline
- Born in New York - Investment ability is unrelated to academic credentials but highly correlated with methodology and discipline
- Joined Graham-Newman Corporation - Choosing to learn from the best often delivers more value than pursuing short-term compensation
- Founded Walter J. Schloss and Associates - Independence is one of the most precious assets for a value investor
Beliefs and mental models
- Buying Below Net Asset Value Is the Most Reliable Margin of Safety - When a stock price is below the company's book net asset value, investors obtain an inherent margin of safety — even if the company operates poorly, asset liquidation can preserve capital. Schloss implemented this principle more purely than anyone.
- Broad Diversification Is the Optimal Strategy When Deep Research Is Impossible - Schloss typically held more than 100 stocks, far exceeding typical value investors. He believed that for investors who cannot deeply research each company, broad diversification effectively reduces individual stock black swan risk while preserving overall value reversion returns.
- Extreme Patience Is the Scarcest Competitive Advantage for Value Investors - Schloss was willing to hold a stock for years or even a decade, waiting for the market to rediscover its value. He believed most investors fail due to lack of patience to wait, not lack of analytical ability.
- Net Asset Value Discount Screener - Systematically screen for stocks priced below book net asset value, using asset liquidation value as the investment safety floor.
- Broad Diversification + Extreme Patience Portfolio Strategy - Hold 100+ undervalued asset stocks, wait for natural market reversion, using diversification to hedge individual stock uncertainty.
- Annual Report Only Decision Method - Reject all non-annual-report information sources; make all buy/sell decisions solely based on public financial reports, eliminating information noise.
