Robert Hagstrom is a senior portfolio manager at EquityCompass Strategies and previously managed the Legg Mason Growth Trust. He has written extensively about Buffett's approach and is one of the most respected secondary analysts of Buffett's methodology. His other books include Investing: The Last Liberal Art and The Detective and the Investor.
Hagstrom traces the intellectual influences that shaped Buffett's approach:
Benjamin Graham: The margin of safety concept, quantitative analysis of cheapness, treating stocks as ownership in businesses.
Philip Fisher: Qualitative business analysis, management evaluation, the scuttlebutt method, holding wonderful businesses forever.
Charlie Munger: Paying fair prices for exceptional businesses rather than cheap prices for mediocre ones, mental models across disciplines.
John Burr Williams: Dividend discount model and the concept that intrinsic value is the present value of future cash flows.
Buffett's synthesis: Graham's price discipline + Fisher's quality analysis + Williams's intrinsic value framework = buying exceptional businesses at fair prices.
Tenet 1: Is the business simple and understandable?
Buffett famously operates within his "circle of competence." He does not invest in businesses he cannot fully understand after reading the annual report. This is not anti-intellectual — it is recognition that understanding a business deeply enough to predict its future cash flows is genuinely difficult, and attempting to do so for complex businesses beyond one's expertise introduces error.
His circle of competence (historical):
Outside his circle (historically avoided):
Tenet 2: Does the business have a consistent operating history?
Buffett looks for businesses that have delivered consistent, predictable results over 10+ years. Consistency suggests a durable competitive advantage, not a temporary product cycle. Companies that frequently change strategy, have experienced leadership turmoil, or operate in volatile industries rarely meet this test.
10-year earnings consistency test:
| Pattern | Interpretation |
|---|---|
| Rising earnings every year, minor variation | Strong consistency; passes test |
| Earnings rising but with occasional setbacks | Good consistency with some cyclicality |
| Highly variable earnings | Cyclical business; requires cyclical analysis |
| Declining earnings | Failing business or secular headwinds |
Tenet 3: Does the business have favorable long-term prospects?
Buffett distinguishes between businesses in secular growth industries and those in secular decline. He is willing to own a slow-growing business in a mature industry if the competitive position is impregnable. He avoids businesses facing structural disruption regardless of how cheap they appear.
The franchise business criterion:
A franchise business:
A franchise business can regularly raise prices without losing customers. Toll bridges, dominant brands, and essential software are franchise businesses. Commodity producers and airlines are not.
Tenet 4: Is management rational?
Buffett focuses on how management allocates capital. A rational management team deploys retained earnings only when returns on reinvestment exceed the cost of capital. When they cannot find attractive reinvestment opportunities, they return capital to shareholders through dividends or buybacks rather than making empire-building acquisitions.
Capital allocation scorecards:
| Action | Rational When | Irrational When |
|---|---|---|
| Reinvest in the business | ROIC > Cost of capital | Returns below cost of capital |
| Make acquisitions | Price below intrinsic value, strategic fit | Overpaying; diversifying for diversification's sake |
| Pay dividends | No better reinvestment opportunities | Always possible if above-average returns available |
| Buy back shares | Price below intrinsic value | Price above intrinsic value |
Tenet 5: Is management candid with shareholders?
Buffett values managers who communicate honestly about failures as well as successes. He is particularly critical of managers who obscure bad results with complex accounting, announce "one-time" charges repeatedly, or attribute failures entirely to external factors.
The honesty test:
Tenet 6: Does management resist the institutional imperative?
The "institutional imperative" is Buffett's term for the pressure on CEOs to follow industry peers, maintain growth at any cost, and perpetuate current strategy regardless of whether it is working. The best managers resist this pressure and act in shareholders' long-term interests regardless of short-term criticism.
Tenet 7: Focus on return on equity, not earnings per share
Earnings per share (EPS) growth can be manufactured through retained earnings reinvestment even if the reinvestment earns poor returns. Return on equity (ROE) measures how efficiently the business uses shareholder capital.
The ROE formula:
ROE = Net Income / Shareholders' EquityBuffett's ROE targets:
| ROE | Assessment |
|---|---|
| Below 10% | Below cost of capital; value-destroying |
| 10-15% | Average business |
| 15-20% | Good business |
| Above 20% | Excellent franchise |
| Above 25% | Exceptional (Coca-Cola, See's Candies) |
Tenet 8: Calculate "owner earnings"
Buffett uses "owner earnings" rather than reported earnings or cash flow from operations:
Owner Earnings = Net Income
+ Depreciation and Amortization
- Capital Expenditures (maintenance capex, not growth capex)
± Changes in Working CapitalThis represents the cash that can actually be distributed to owners without impairing the business's competitive position. It is the closest approximation to true economic earnings.
Distinguishing maintenance from growth capex:
| Type | Purpose | Treatment |
|---|---|---|
| Maintenance capex | Keep existing equipment functioning | Subtract from owner earnings |
| Growth capex | Build new capacity for future growth | Optional; funded from retained earnings or debt |
Tenet 9: Look for companies with high profit margins
High profit margins indicate either pricing power (franchise businesses) or operational efficiency. Both are valuable.
Buffett's historical investments — profit margins:
| Company | Gross Margin | Operating Margin | Why Attractive |
|---|---|---|---|
| Coca-Cola | ~60% | ~25% | Brand franchise |
| See's Candies | ~55% | ~20% | Regional brand loyalty |
| GEICO | N/A (insurance) | ~15% combined ratio advantage | Cost efficiency |
| Washington Post | ~50% | ~20% | Local monopoly |
Tenet 10: What is the value of the business?
Buffett's intrinsic value framework uses the John Burr Williams dividend discount model:
Intrinsic Value = Present Value of All Future Owner EarningsIn practice, this requires:
Buffett's practical simplification:
For businesses with predictable, growing cash flows, Buffett uses a two-stage model:
Tenet 11: Can the business be purchased at a significant discount to its value?
Buffett requires a margin of safety even for exceptional businesses. He would rather pay a fair price for a wonderful business than a cheap price for a mediocre one — but "fair price" still means below intrinsic value.
Buffett's margin of safety by business quality:
| Business Quality | Required Discount to Intrinsic Value |
|---|---|
| Exceptional franchise (Coca-Cola) | 15-25% |
| Very good business (Wells Fargo) | 20-30% |
| Good business | 30-40% |
| Average business | Would not buy regardless of discount |
Hagstrom dedicates significant attention to Buffett's portfolio approach, which he calls "focus investing" — the antithesis of modern portfolio theory.
Buffett on diversification:
"Diversification is protection against ignorance. It makes little sense if you know what you are doing."
The focus portfolio vs. diversified portfolio:
| Characteristic | Focus Portfolio | Diversified Portfolio |
|---|---|---|
| Number of holdings | 5-15 | 50-500+ |
| Research per holding | Very deep | Shallow |
| Expected alpha from selection | High (if analysis is correct) | Low |
| Risk of individual error | High | Low |
| Risk of systematic error | Low | High |
Buffett argues that owning 15 thoroughly researched businesses reduces the risk of being wrong on any single one while maintaining the return potential of genuine insights. Owning 500 businesses eliminates individual stock risk but also eliminates the ability to earn above-market returns.
The Kelly criterion applied to focus investing:
Optimal position size = (Probability of win × Win amount - Probability of loss × Loss amount) / Win amountFor a position with 70% probability of doubling and 30% probability of losing 50%, Kelly suggests:
(0.70 × 1.00 - 0.30 × 0.50) / 1.00 = (0.70 - 0.15) / 1.00 = 55%Putting 55% of capital in one investment is too aggressive for psychological comfort. Most practitioners use "half Kelly" (27.5%), which is still a very large position by conventional standards.
The situation: GEICO had nearly gone bankrupt after writing too much high-risk business. The new CEO (Jack Byrne) had a clear turnaround plan.
Why Buffett bought:
The result: Buffett's $45 million investment grew to represent $1.7 billion at the time of Berkshire's full acquisition in 1996.
The situation: Coca-Cola had recovered from the New Coke disaster of 1985. New management under Roberto Goizueta was aggressively expanding internationally and focused on return on equity.
Why Buffett bought (one-third of Berkshire's equity portfolio):
Owner earnings growth rate Buffett used: 15% for first 10 years, then 5% perpetuity
Result: $1.3 billion investment grew to $13+ billion at peak; still held as of 2024.
Q: Is this better than The Essays of Warren Buffett for understanding his approach?
A: Different purposes. The Essays is primary source material — Buffett's own words. The Warren Buffett Way is systematic analysis — Hagstrom's organization of those principles. Read both for the complete picture.
Q: Can individual investors replicate Buffett's approach?
A: The principles (identify franchise businesses, evaluate management, calculate owner earnings, require margin of safety) are fully applicable to individual investors. Buffett's informational and capital advantages are not replicable, but his analytical framework is.
Rating: 4.6/5
The Warren Buffett Way is the most systematic account of Buffett's investment methodology available. Its four-tenet framework, owner earnings concept, and focus investing philosophy provide a complete toolkit for fundamental stock analysis. Essential reading alongside The Intelligent Investor and Common Stocks and Uncommon Profits.
