Walter Schloss (August 28, 1916 – February 19, 2012) was one of the most successful value investors to have ever played the game.

From 1956 to 1984, his partnership produced a compound annual return of over 21%. He continued to manage his fund until 2000, eventually earning 15.3% per annum for over four and a half decades!

Many investors have never heard of him, but we can all learn a lot from Walter Schloss.

So who was he?

Walter Schloss proves that you don’t need fancy diplomas, a genius IQ, or numerous letters before or after your name to be successful in the stock market – you need only have passion for your work and discipline over your own emotions.

Schloss never had a formal education. When he was 18, he started working as a runner on Wall Street. He then attended investment courses taught by Ben Graham at the New York Stock Exchange Institute, and eventually worked for Graham in the Graham-Newman Partnership.

In 1955, he left Graham’s company and set up his own investment firm, which he ran for nearly 50 years.

Walter Schloss was one of the 9 “superinvestors” that Warren Buffett wrote about in his legendary “The Superinvestors of Graham-and-Doddsville” article (a list that included Charlie Munger and Warren Buffett himself).

Schloss’s return of over 15% per annum for nearly 50 years solidifies him as one of the most consistently successful investors ever (see the chart below).

Walter Schloss had the following to say about his investment philosophy (courtesy of Old School Value):

When it comes to investing, my suggestion is to first understand your strengths and weaknesses, and then devise a simple strategy so that you can sleep at night.

I don’t like stress and prefer to avoid it, I never focus too much on market news and economic data. They always worry investors.

You have to invest the way that’s comfortable for you.

Try not to let your emotions affect your judgment. Fear and greed are probably the worst emotions to have in connection with the purchase and sale of stocks.

I think investing is an art, and we tried to be as logical and unemotional as possible. Because we understood that investors are usually affected by the market, we could take advantage of the market by being rational. As [Benjamin] Graham said, ‘The market is there to serve you, not to guide you!’

I like Ben’s analogy that one should buy stocks the way you buy groceries not the way you buy perfume.

The ability to think clearly in the investment field without the emotions that are attached to it is not an easy undertaking. Fear and greed tend to affect one’s judgment.

The concepts described above by Walter Schloss can also be found in Ben Graham’s “The Intelligent Investor” or in many quotes by Warren Buffett. But Schloss was definitely a purer disciple of Graham’s actual investment strategy than Warren is, evidenced by the following Walter Schloss quotes:

Don’t buy on tips or for a quick move. Let the professionals do that, if they can.

Remember that a share of stock represents a part of a business and is not just a piece of paper.

Prefer stocks over bonds. Bonds will limit your gains and inflation will reduce your purchasing power.

Listen to suggestion from people you respect. This doesn’t mean you have to accept them. Remember it’s your money and generally it is harder to keep money than to make it. Once you lose a lot of money it is hard to make it back.

Most look at earnings and earnings potential, well I can’t get into that game.

I used the same investment approach I used at Graham-Newman finding net-net stocks. It was all about capital preservation because I had to serve in the best interests of my investors. Many of them were not wealthy, and they needed me to generate returns that would allow them to cover their living expenses.

I try to protect myself from permanent loss of capital by investing in stocks that are depressed.

When you buy a depressed company it’s not going to go up right after you buy it, believe me.

I like to buy companies with very little debt so it has a margin of safety.

I like to buy basic businesses not high flyers that sell at huge multiples.

I’m not very good at judging people. So I found that it was much better to look at the figures rather than people.

We don’t own stocks that we’d never sell. I guess we are a kind of store that buys goods for inventory (stocks) and we’d like to sell them at a profit within 4 years if possible.

Remember the word compounding. For example, if you can make 12% a year and reinvest the money back, you will double your money in 6 years, taxes excluded. Remember the rule of 72. Your rate of return into 72 will tell you the number of years to double your money.

You never really know a stock until you own it.


Walter Schloss was undoubtedly one of the great value investors of all time, and truly a “superinvestor”. And while finding 100 stocks that fit his exact investment criteria might be a difficult task in today’s market, his thoughts on knowing your own strengths and weaknesses (just as well as your stocks’ strengths and weaknesses) and understanding and controlling your emotions will always be timeless lessons.

What do YOU think of Walter Schloss’s investment strategy of finding deeply discounted stocks and selling them once they reach their intrinsic value, versus Warren’s strategy of buying inexpensive yet “wonderful” businesses and holding them forever? Which one do you follow? Which one’s better? I’d love to hear your thoughts in the comments below!
