Walter Schloss investing approach: A long-only, highly diversified value strategy that buys stocks trading at steep discounts to book value and holds them patiently for mean reversion, relying solely on audited balance sheets and extreme discipline.
Walter Schloss never visited a company. He never spoke to management. He didn't use a computer until he was forced to. He didn't have an MBA, or any college degree at all — just a high school diploma and a course he took from Benjamin Graham at the New York Institute of Finance in 1946.
For forty-eight years, from 1955 to 2003, he ran a small investment partnership from a tiny office he shared with his son Edwin. He bought stocks trading below their net asset value, waited for the market to recognize the discrepancy, and sold. That was it.
His compound annual return was 15.7%, nearly doubling the S&P 500 over the same period.
The Method
Schloss's approach was so simple it embarrassed people. He described it himself in a 1994 talk titled "Factors Needed to Make Money in the Stock Market":
- Price is the most important factor. Buy below book value.
- Try to establish the value of the company. Remember that a share of stock represents a part of a business.
- Use book value as a starting point. Try to buy assets at a discount.
- Have patience. Stocks don't go up immediately.
- Don't buy on tips or for quick moves.
- Be willing to hold a stock for several years.
- Don't be afraid to be a loner. But make sure you're right.
No DCF models. No earnings projections. No macro calls. No management meetings. Just audited balance sheets and patience.
Why It Worked
Buffett, in his famous 1984 speech "The Superinvestors of Graham-and-Doddsville", included Schloss as Exhibit A. He pointed out that Schloss's returns were not explained by risk, by leverage, or by luck. They were explained by a method: buying dollar bills for fifty cents, diversifying broadly, and waiting.
The key insight is that Schloss didn't need to be smarter than the market. He just needed to be more patient. While other investors chased growth stories and momentum, Schloss quietly bought what nobody wanted and waited for mean reversion.
Munger described it this way:
He just kept turning over rocks. Forty-eight years of turning over rocks.
The Character
What made Schloss remarkable wasn't just his returns. It was his character.
He lived simply. He took a modest salary. He charged his partners far less than the industry standard — no management fee, just 25% of profits above a 6% hurdle. When he closed the partnership in 2003 at age 87, he wrote his partners a characteristically understated letter:
"I have a great deal of satisfaction in looking back on the past 45½ years... I feel that the record speaks for itself."
No victory lap. No memoir. No speaking tour.
What Schloss Teaches
In an era of algorithmic trading, alternative data, and AI-powered analysis, Schloss reminds us of something uncomfortable: the edge isn't always in having more information. Sometimes it's in needing less.
His method required three things:
- Discipline to buy what's cheap, not what's exciting
- Patience to wait years for value to be recognized
- Independence to ignore what everyone else was doing
These are not intellectual skills. They are character traits. And they are, in Spinoza's words, tam difficilia, quam rara sunt — as difficult as they are rare.
Sustine et abstine. Bear and forbear. Walter Schloss did both for forty-eight years.
