Quick Overview

Philip Fisher published Common Stocks and Uncommon Profits in 1958 and it immediately became a classic. Warren Buffett has said he is "85% Graham and 15% Fisher" — this book is where the 15% came from. Where Graham focused on quantitative analysis of balance sheets to find cheap stocks, Fisher focused on qualitative analysis of business quality to find great companies worth holding forever. His influence on Buffett's evolution from net-net bargain hunter to franchise business owner was decisive.

About the Author

Philip Fisher (1907-2004) ran Fisher & Co., a San Francisco-based investment firm, for over 70 years. He identified Motorola in 1955 and held it until his death — nearly 50 years. He identified Texas Instruments in the 1950s at a few dollars per share. His investment record over seven decades is one of the most distinguished in the history of the profession. He was famously selective: he might investigate 20 companies before finding one worth buying. He had no use for speculation, momentum, or short-term trading.


The Scuttlebutt Method

Fisher's most original contribution to investment research is the "scuttlebutt" method: gathering information about a company from its ecosystem of competitors, customers, suppliers, former employees, and industry experts.

Why Scuttlebutt Works

Annual reports and financial statements tell you what happened. They do not tell you:

  • Whether management is executing their stated strategy
  • How employees view the company's future
  • Whether customers are satisfied or preparing to switch
  • What competitors fear about this company
  • Whether the R&D pipeline is strong or empty
  • Scuttlebutt fills these gaps with direct observation and conversation.

    The Scuttlebutt Sources

    SourceWhat They KnowHow to Access
    CompetitorsRelative competitive position, product qualityCompetitor annual reports, industry conferences
    CustomersProduct value, customer service, switching likelihoodCustomer interviews, product reviews
    Former employeesCulture, management quality, internal strategyLinkedIn, referrals
    SuppliersGrowth trajectory, payment practices, customer importanceSupplier relations contacts
    Industry expertsTechnical capability, market positionAcademic researchers, consultants
    Trade publicationsIndustry dynamics, competitive threatsSubscription trade journals

    Fisher spent weeks researching a single company before buying. Modern investors can access much of this information through:

  • Glassdoor (employee reviews)
  • Trustpilot and G2 (customer reviews)
  • Reddit communities (user communities for technology products)
  • SEC filings (including risk factor disclosures that competitors are required to make)
  • Earnings call transcripts (competitors discussing the same market)
  • LinkedIn (former employee patterns)
  • The Scuttlebutt Verification Loop

    Fisher used each source to verify and extend what he learned from others:

    Annual report → Initial hypothesis about management quality
        ↓
    Competitor interviews → Does the industry see what management claims?
        ↓
    Customer interviews → Are the claimed competitive advantages real?
        ↓
    Former employee conversations → Is the culture consistent with management's public statements?
        ↓
    Supplier conversations → Is the business growing as management claims?
        ↓
    Decision: Confirmed thesis → Buy / Disconfirmed → Pass

    The 15 Points

    Fisher's core framework is 15 qualitative criteria for evaluating whether a company is truly exceptional:

    Point 1: Does the Company Have Products or Services With Sufficient Market Potential?

    Fisher seeks companies whose addressable market will allow significant growth for many years. A company that has saturated its current market cannot grow regardless of how well it executes.

    Identifying large addressable markets:

  • Is the total market growing?
  • Can the company expand into adjacent markets?
  • Is there international expansion opportunity?
  • Is there a platform that can host multiple product lines?
  • Point 2: Does Management Have the Determination to Continue Developing Products?

    Fisher distinguishes between companies that grow until they exhaust their current product line and those that continuously reinvest in developing the next generation. The latter are worth significantly more.

    Examples of continuous product development:

  • 3M's culture of innovation (Fisher's era: plastics and adhesives; later: Post-it Notes, medical devices)
  • Motorola's consistent push into new markets (Fisher's era: car radios; later: semiconductors)
  • Today: Amazon (AWS as the second business), Apple (iPhone to services), Google (search to cloud)
  • Point 3: How Effective Is the Company's Research and Development?

    Not all R&D is equal. Fisher focuses on R&D efficiency: how much revenue and profit does the company generate per dollar of R&D spending?

    R&D effectiveness metrics:

    MetricFormulaTarget
    R&D as % of revenueR&D spend / RevenueConsistent with industry; growing
    Revenue per R&D dollarRevenue / R&D spendRising over time
    New product revenue %Revenue from products < 5 years oldAbove 30% for innovation leaders

    Point 4: Does the Company Have an Above-Average Sales Organization?

    A great product that is poorly sold produces inferior results. Fisher checks whether the sales organization can effectively communicate the product's value to the right customers.

    Point 5: Does the Company Have a Worthwhile Profit Margin?

    High gross margins indicate pricing power — the ability to charge more than the cost of production. Fisher's rule: in any industry, look for the companies with consistently higher margins than competitors. This is usually a sign of genuine competitive advantage.

    Margin analysis:

    Margin TypeStrongAverageWeak
    Gross marginAbove 40%20-40%Below 20%
    EBIT marginAbove 20%10-20%Below 10%
    Net marginAbove 15%5-15%Below 5%

    These vary significantly by industry. The relevant comparison is always within an industry: a software company with a 70% gross margin and a cement company with a 25% gross margin are not comparable. Compare within sectors.

    Point 6: What Is the Company Doing to Maintain or Improve Profit Margins?

    Fisher looks for companies actively working to improve margins through:

  • Cost reduction programs
  • Automation investment
  • Product mix improvement (shifting toward higher-margin products)
  • Pricing discipline
  • Point 7: Does the Company Have Outstanding Labor and Personnel Relations?

    Fisher found that companies with genuine respect for employees consistently outperformed over long periods. Good labor relations reduce turnover (expensive to replace skilled workers), increase productivity, and improve morale.

    Signals of strong labor relations:

  • Low voluntary turnover relative to industry
  • Employee reviews (Glassdoor) above industry average
  • Union relations (for unionized industries) — cooperative rather than adversarial
  • Management accessibility and communication
  • Point 8: Does the Company Have Outstanding Executive Relations?

    Beyond the CEO, Fisher examines the depth of management talent. Great CEOs surrounded by weak lieutenants are vulnerable. The best companies develop talent internally and promote from within.

    Point 9: Does the Company Have Depth to Its Management?

    A company where every important decision flows through one person is fragile. Fisher looks for organizations that can function and grow even as individual managers change.

    Point 10: How Good Are the Company's Cost Analysis and Accounting Controls?

    Fisher's check against the scuttlebutt: do the financial statements reflect what the operating data would predict? Discrepancies between what management says about operations and what the financials show are warning signs.

    Point 11: Are There Other Aspects of the Business Somewhat Peculiar to the Industry That Will Give the Investor Important Clues?

    Fisher's catch-all for industry-specific factors — patent protections, regulatory environments, customer concentration, capital requirements, and other industry-specific characteristics that determine long-term returns.

    Point 12: Does the Company Have a Short-Range or Long-Range Outlook on Profits?

    Fisher strongly prefers management teams that think in years and decades rather than quarters. Companies that sacrifice long-term investment to hit quarterly earnings estimates consistently underperform those that invest for the future even when it temporarily hurts reported earnings.

    Point 13: In the Foreseeable Future Will the Growth of the Company Require Sufficient Equity Financing?

    Growth that requires constant dilutive share issuance transfers value from existing shareholders to new investors. Fisher prefers companies that can finance growth internally through retained earnings, or through debt if the returns justify it.

    Point 14: Does Management Talk Freely to Investors About Its Affairs When Things Are Going Well but "Clam Up" When Troubles and Disappointments Occur?

    Management teams that communicate only good news and go silent on bad news are not trustworthy stewards of shareholder capital. Fisher values management teams that discuss problems candidly and explain how they plan to address them.

    Point 15: Does the Company Have Management of Unquestionable Integrity?

    The most important and least quantifiable criterion. Fisher believes no stock with questionable management deserves to be bought regardless of how attractive the numbers look.


    The "When to Sell" Framework

    Fisher is unusual among value investors in having a clear "when to sell" framework. His answer: almost never, but specifically when:

  • You made a mistake: The original analysis was wrong. The company does not actually have the qualities you thought.
  • The company has changed: Management quality has deteriorated, competitive position has weakened, or the original growth drivers have expired.
  • You find something clearly better: You have found a company that scores much higher on all 15 criteria and the valuation gap justifies switching.
  • What Fisher does NOT consider as reasons to sell:

  • The stock has doubled or tripled (the price gain does not change the underlying business quality)
  • The market has declined (short-term price changes do not affect long-term business value)
  • The stock looks expensive by historical P/E standards (great businesses often look expensive on current earnings; they are cheap on future earnings)
  • Fisher's most important selling insight:

    "If the job has been correctly done when a common stock is purchased, the time to sell it is — almost never."

    Fisher's Investment Philosophy Applied to Motorola

    Fisher bought Motorola in 1955. Here is how it scored on his criteria at purchase:

    CriterionAssessment
    Market potentialEnormous — consumer electronics just beginning
    Product development determinationExceptional — constant innovation culture
    R&D effectivenessIndustry-leading patents in transistor technology
    Sales organizationStrong retail and commercial relationships
    Profit marginsAbove industry average consistently
    Labor relationsRespected employer in the Chicago area
    Management depthStrong bench under Bob Galvin
    Long-range outlookExplicitly communicated multi-decade vision
    Equity financingSelf-financing through retained earnings
    Management integrityGalvin family reputation beyond question

    Fisher held Motorola until his death in 2004 — 49 years — through television, consumer electronics, semiconductor, cell phone, and government systems cycles.

    The result: A tiny initial investment grew to an enormous sum through decades of compounding. Fisher's point: finding truly great companies and holding them through normal market volatility produces better results than constantly seeking new opportunities.


    Fisher vs. Graham: The Complementary Approaches

    ApproachGrahamFisher
    Primary focusQuantitativeQualitative
    Key metricNet asset value, P/EBusiness quality, management
    Time horizonShorter (sell at fair value)Longer (hold forever)
    DiversificationWider portfolioConcentrated (few stocks)
    Information sourceFinancial statementsScuttlebutt research
    Buy signalCheap vs. assetsQuality at reasonable price
    Best suited forBear markets, asset-heavy industriesGrowth companies, technology

    Warren Buffett synthesized these approaches: Graham's margin of safety for the entry price, Fisher's quality analysis for what to buy. The combination is more powerful than either alone.


    Strengths & Weaknesses

    What We Loved

  • The 15 points provide the most rigorous qualitative evaluation framework in any investing book
  • Scuttlebutt method is original, practical, and timeless
  • Management evaluation is more sophisticated than any contemporary framework
  • "When to sell" framework is one of the few honest treatments of the most difficult question in investing
  • Motorola case study demonstrates extraordinary long-term compounding in practice
  • Areas for Improvement

  • Qualitative focus means limited quantitative guidance; needs supplementation with valuation frameworks
  • 1958 language and examples require mental translation for modern industries
  • Extremely time-intensive — the scuttlebutt method as Fisher describes it requires weeks per company
  • Technology companies he analyzed no longer exist; translating principles to modern software businesses requires work

  • Who Should Read This Book

  • Investors who have mastered Graham and want the quality dimension
  • Those interested in growth investing grounded in business quality rather than momentum
  • Analysts and portfolio managers building comprehensive research processes
  • Anyone who has been puzzled by why great businesses seem "expensive" yet continue to compound
  • Probably Not For

  • Complete beginners (read The Intelligent Investor first)
  • Passive index investors
  • Investors without time for deep research

  • Frequently Asked Questions

    Q: Is Fisher's approach compatible with index investing?

    A: The principles can inform your thinking about what you own. Practically, the time commitment for the full scuttlebutt method makes it suited to concentrated active portfolios rather than index supplements.

    Q: How relevant is the scuttlebutt method in the internet age?

    A: More accessible than ever. Customer reviews, Glassdoor, Reddit communities, LinkedIn, and free earnings call transcripts provide more scuttlebutt data than Fisher ever had. The method is more powerful today than in 1958.

    Q: What is the single most important Fisher principle?

    A: Point 15 — management integrity. No amount of analytical sophistication compensates for management that steals from shareholders or misleads investors. Start there and work backwards.


    Final Verdict

    Rating: 4.7/5

    Common Stocks and Uncommon Profits is the essential complement to The Intelligent Investor. Where Graham gives you the price discipline, Fisher gives you the quality framework. Together they form the foundation of intelligent investing. The 15 points and scuttlebutt method remain the best available tools for evaluating whether a business is genuinely excellent.
