Introduction: The Perils of Misinformation in Investing
Benjamin Graham warned in Security Analysis that capital markets often spawn deceptive theories due to enormous profit incentives—like the infamous "New Era Theory" that fueled the 1920s bubble preceding the Great Depression. Philip Fisher was more blunt, opening Common Stocks and Uncommon Profits by declaring: "The stock market is filled with individuals who know the price of everything and the value of nothing."
Warren Buffett's decades-long critique of Wall Street practices—particularly his attacks on EMH (Efficient Market Hypothesis), Beta, and EBITDA—reveals how financial institutions often misrepresent risk/reward dynamics. Our research shows these criticisms aren't mere philosophical differences; they strike at the foundation of modern portfolio theory and conventional investment practices.
The "Duck-Rabbit Illusion" in Market Psychology
This cognitive phenomenon—first demonstrated by Joseph Jastrow in 1899—shows how identical data can yield contradictory interpretations based on perspective. Wittgenstein later analyzed it as seeing-as: the left curve viewed as a "duck bill" organizes the right half as a "duck head," while seeing it as "rabbit ears" restructures the entire image.
Buffett showcased this illusion at the 2022 shareholder meeting to explain market confusion:
"Before reading Chapter 8 of The Intelligent Investor, I traded stocks technically—analyzing charts and chasing tips. Graham's principle—'buying stocks means buying businesses'—was my epiphany."
Wall Street vs. Value Investing Lenses
| Perspective | Risk Definition | Reward Metric |
|---|---|---|
| Wall Street | Beta/Volatility | EBITDA/EPS Growth |
| Value Investing | Permanent Capital Loss | Margin of Safety |
The EBITDA Deception: Why Buffett Calls It "Nonsense"
Buffett and Munger's vehement criticism—"utter nonsense" and "bullshit earnings"—stems from how EBITDA ignores real expenses:
- Depreciation: Equipment wears out. A $100M asset depreciating over 5 years requires $20M annually in real replacement costs—yet EBITDA treats this as discretionary.
- Amortization: Goodwill from overpriced acquisitions (e.g., startups with "story value") creates accounting distortions. GAAP-mandated amortization often gets obscured by EBITDA reporting.
- Capital Expenditures: Maintaining competitiveness demands ongoing investments—EBITDA's exclusion of CapEx paints false profitability.
Free Cash Flow Truth
The accurate measure:
FCFF = EBIT(1-T) + Depreciation - CapEx - ΔWorking Capital
EBITDA distorts three FCFF components, leading to:
- Misjudged intrinsic values
- Confused risk assessments
- Long-term holdings in deteriorating businesses
Case Study: Market Panics and Value Opportunities
Imagine a quality asset with $1 intrinsic value:
- At $0.60: Margin of safety exists
- During panic at $0.40: EMH adherents see "fair price," while value investors see maximum opportunity—the quintessential "duck-rabbit" divergence.
Buffett's analogy:
"Measuring risk by Beta is like calling a dog’s tail a 'fifth leg.' When the tail wags, EMH theorists get shocked."
FAQs: Clarifying Core Concepts
Q1: Why does Buffett reject modern financial theories?
A: Tools like Beta measure price volatility—not business risk. Value investing assesses fundamental risks: competitive moats, management quality, etc.
Q2: How does EBITDA mislead investors?
A: By excluding depreciation/amortization, it overstates cash flows—especially dangerous for asset-heavy industries (e.g., telecoms, utilities).
Q3: What’s the "Duck-Rabbit Illusion" in markets?
A: When identical data appears bullish (e.g., low P/E) or bearish (e.g., high Beta) based on analytical frameworks—highlighting why perspective matters.

Conclusion: The Omaha Airport Test
During the 2025 Berkshire meeting, a subtle airport billboard read:
"Check your baggage for SPACs, Crypto, and EBITDA." This encapsulates Buffett’s warnings:
- SPACs: "Blank-check" companies often destroy value
- Crypto: "Rat poison squared" with no intrinsic value
- EBITDA: Accounting fantasy masking real expenses
True value investors must:
- Define risks as business fundamentals, not price swings
- Measure rewards via free cash flows, not earnings proxies
- Recognize when conventional metrics become dangerous illusions
The final question: Are you seeing ducks when rabbits are staring you in the face?
