The Superinvestors of Graham and Doddsville Explained: A Clear Guide for Investors
The superinvestors of Graham and Doddsville refers to a group of investors highlighted by Warren Buffett in his 1984 Columbia Business School speech who all trained under Benjamin Graham and all beat the market decisively over long periods. Buffett's argument was elegant: if nine coin-flippers from the same village all flip heads 80% of the time, it is not luck. It is something about the village. That "village" was the intellectual framework of Graham-and-Dodd value investing, and the evidence Buffett presented remains one of the strongest cases ever made for active stock picking.
Key Takeaways
- Warren Buffett delivered his "Superinvestors" speech in 1984 to counter the efficient market hypothesis, which claimed no investor could consistently beat the market
- All nine highlighted investors studied under Benjamin Graham at Columbia, yet built completely different portfolios
- Their returns ranged from 18% to 33% annually over periods of 13 to 28 years
- The common factor was not a specific stock pick but a shared discipline: buying below intrinsic value with a margin of safety
- You can still apply Graham-and-Doddsville principles today using fundamental screening tools
The Context: Why Buffett Gave This Speech
In the early 1980s, the efficient market hypothesis (EMH) dominated academic finance. Professors at the University of Chicago argued that stock prices already reflected all available information, making it impossible for any investor to outperform the market consistently.
Buffett saw this as not just wrong but provably wrong. His speech at Columbia's celebration of the 50th anniversary of Graham and Dodd's "Security Analysis" was designed to end the debate with data.
He used an analogy. Imagine a national coin-flipping contest where 225 million Americans each bet $1 on a daily coin flip. After 20 days, roughly 215 people would have won 20 consecutive flips. EMH proponents would say these winners were statistically expected and their success was random.
But what if 40 of those 215 winners all came from the same small town? That would demand explanation. And that is exactly what Buffett found in the real investing world.
The Nine Superinvestors
Buffett profiled investors who all learned from Graham but invested independently, in different stocks, from different cities. The table below summarizes their track records.
| Investor | Fund/Entity | Annual Return | Period | S&P 500 (same period) |
|---|---|---|---|---|
| Walter Schloss | WJS Partners | 21.3% | 1956-1984 | ~10% |
| Tom Knapp | Tweedy Browne | 20.0% | 1968-1983 | ~8% |
| Warren Buffett | Buffett Partnership | 29.5% | 1957-1969 | ~9% |
| Bill Ruane | Sequoia Fund | 18.2% | 1970-1984 | ~10% |
| Charles Munger | Wheeler Munger | 19.8% | 1962-1975 | ~5% |
| Rick Guerin | Pacific Partners | 32.9% | 1965-1983 | ~8% |
| Stan Perlmeter | Perlmeter Investments | 23.0% | 1965-1983 | ~8% |
Each investor built a different portfolio. Schloss held 100+ cheap stocks at any time. Munger concentrated in 3-5 positions. Ruane favored quality growth companies. Yet they all outperformed.
The Intellectual Framework They Shared
What connected these investors was not a stock list. It was a set of principles from Benjamin Graham's teaching.
Intrinsic value exists and can be estimated. Graham taught that every business has a value based on its assets, earnings, and growth prospects. This value exists independently of the stock price. When the market prices a stock below its intrinsic value, an opportunity emerges.
Margin of safety protects against errors. No estimate of intrinsic value is perfect. Buying at a significant discount, say 30-40% below estimated value, creates a buffer. Even if your estimate is off by 20%, you still purchased below true worth.
Mr. Market is your servant, not your master. Graham personified the stock market as "Mr. Market," an emotional neighbor who offers to buy or sell stocks at different prices every day. Sometimes his prices are reasonable, sometimes absurd. The investor's job is to take advantage of his irrational offers, not follow them.
Using the ValueMarkers screener, you can apply these same principles today. Filter for stocks trading below their Graham Number, with Piotroski F-Scores of 7+ (like Visa at Piotroski 8), and a margin of safety of 30%+ based on DCF intrinsic value estimates.
Why Different Styles All Worked
One of the most powerful aspects of Buffett's argument was the diversity of approaches among the superinvestors.
Walter Schloss barely left his office. He relied almost entirely on financial statements, looking for stocks trading below book value with low debt. He held over 100 positions at a time and rarely met with management.
Charlie Munger took the opposite approach. He concentrated in a handful of businesses he understood deeply, willing to pay slightly higher prices for exceptional quality. His portfolio rarely held more than 5 stocks.
Bill Ruane at the Sequoia Fund blended the two approaches. He held 15-25 positions and favored companies with competitive advantages, what Buffett would later call "moats."
The common denominator was not position count, sector focus, or market capitalization. It was the discipline of paying less than a business was worth and waiting patiently for the market to recognize the gap.
The Academic Response
The efficient market hypothesis did not die overnight after Buffett's speech, but it was wounded. Eugene Fama, the father of EMH, later co-authored research with Kenneth French showing that value stocks (low P/E, low P/B) systematically outperformed growth stocks, a finding that aligned perfectly with Graham-and-Doddsville principles.
By the 1990s, even EMH proponents had shifted to a "weak form" of the hypothesis, acknowledging that certain fundamental strategies could produce excess returns. The Fama-French three-factor model explicitly included a value premium.
Berkshire Hathaway (P/E 9.8, P/B 1.5) itself became the longest-running proof. Over 58 years, Buffett compounded at 19.8% annually versus the S&P 500's 9.9%. The probability of that being random chance is effectively zero.
Applying Graham-and-Doddsville Principles Today
The stocks available to investors have changed since 1984. The principles have not.
Step 1: Estimate intrinsic value. Use a discounted cash flow model or the Graham Number to estimate what a business is worth. The ValueMarkers DCF calculator automates this across thousands of stocks.
Step 2: Demand a margin of safety. Only buy when the market price is at least 25-30% below your intrinsic value estimate. If Johnson & Johnson (P/E 15.4, ROIC 18.3%) trades at a 10% discount, that might not be enough margin.
Step 3: Focus on fundamentals. Ignore stock price momentum, chart patterns, and market timing. Analyze earnings quality, return on invested capital, and balance sheet strength. A Piotroski F-Score of 7+ signals strong fundamentals.
Step 4: Be patient. The superinvestors held positions for years. The average holding period among the Graham-and-Doddsville group exceeded 5 years. Short-term underperformance is the price of long-term outperformance.
Step 5: Stay within your circle of competence. Every superinvestor focused on businesses they understood deeply. If you cannot explain how a company makes money in two sentences, move on to the next idea.

Frequently Asked Questions
what happens if the stock market crashes
Market crashes are buying opportunities for value investors following Graham-and-Doddsville principles. During the 2008-2009 crash, stocks in the S&P 500 fell an average of 57% from peak to trough, pushing many quality companies well below intrinsic value. Investors who had cash and the discipline to buy during the panic, like Buffett purchasing Goldman Sachs preferred shares, generated returns exceeding 100% over the following 3 years.
what time does the stock market open
The U.S. stock market (NYSE and NASDAQ) opens at 9:30 AM Eastern Time on regular trading days. Pre-market trading begins as early as 4:00 AM ET on most brokerages, though liquidity is thin. The ValueMarkers screener tracks stocks across 73 global exchanges, each with different trading hours, from the Tokyo Stock Exchange opening at 9:00 AM JST to the London Stock Exchange at 8:00 AM GMT.
what time does the stock market close
The U.S. stock market closes at 4:00 PM Eastern Time. After-hours trading continues until 8:00 PM ET, but with wider bid-ask spreads and lower volume. Value investors following superinvestor strategies rarely need to worry about intraday timing since their holding periods span years, not hours.
when does the stock market open
Regular U.S. stock market hours are 9:30 AM to 4:00 PM Eastern Time, Monday through Friday, excluding federal holidays. The market is closed on approximately 9 holidays per year. Extended hours trading is available but carries higher risk due to reduced liquidity and wider spreads.
why is the stock market down today
Daily stock market declines are driven by a combination of earnings misses, macroeconomic data releases, geopolitical events, and investor sentiment shifts. From a Graham-and-Doddsville perspective, daily price movements are noise. The average intraday S&P 500 move is about 0.7%, which over a single year sums to moves of roughly 175%. What matters is whether stocks are priced above or below intrinsic value, not whether the market is up or down on any given day.
how is the stock market doing today
Real-time market performance can be checked on any financial news site or through your brokerage platform. For value investors, the more relevant question is how individual stocks compare to their intrinsic values. The ValueMarkers screener lets you filter the entire global market by valuation metrics like P/E ratio, P/B ratio, and Graham Number, giving you a snapshot of where the market stands relative to fundamental value rather than just a price number.
