1. Overview
Michael Shearn is a value investor and portfolio manager at Compound Money, LP,
a concentrated value fund. His investment approach is deeply influenced by Warren
Buffett, Charlie Munger, and the broader value investing tradition, but his
unique contribution is the systematization of the research process into a
comprehensive checklist.
The Investment Checklist (2012) is built on a simple but powerful premise:
investment mistakes are rarely the result of missing some exotic piece of
information. They are almost always the result of failing to ask basic questions
that, had they been asked, would have revealed obvious problems. A checklist
ensures that no critical question is skipped, regardless of how excited or
pressured the investor feels.
The book draws on the checklist revolution that Atul Gawande documented in
medicine and aviation β domains where the consequences of oversight are severe
and where checklists have dramatically reduced errors. Shearn argues that
investing is similarly high-stakes and similarly prone to avoidable errors of
omission.
1.1 Why Checklists Work
Checklists work not because they contain esoteric knowledge, but because they
impose discipline on a process that is otherwise vulnerable to emotion, bias,
and haste:
| Problem |
How a Checklist Helps |
| Confirmation bias |
Forces examination of disconfirming evidence |
| Anchoring |
Requires multiple valuation approaches |
| Overconfidence |
Demands explicit risk identification |
| Omission |
Ensures every critical dimension is examined |
| Recency bias |
Requires historical analysis, not just current snapshot |
| Narrative fallacy |
Forces quantitative backing for qualitative claims |
1.2 How to Use This Specification
This document organizes Shearn's checklist into functional categories: business
understanding, management evaluation, financial analysis, and valuation. Each
section contains the key questions, the reasoning behind them, and guidance on
what constitutes a satisfactory answer. The complete checklist at the end serves
as a practical tool for investment research.
2. The Checklist Philosophy
2.1 The Circle of Competence
Before applying the checklist, the investor must first determine whether the
business falls within their circle of competence β the domain of businesses they
can genuinely understand. Shearn emphasizes that no checklist can substitute for
genuine understanding:
- Can you explain the business to a ten-year-old? If you cannot, you do not
understand it well enough to invest.
- Do you understand how the business makes money? Not in general terms, but
specifically β what products, what customers, what pricing, what cost structure.
- Can you identify the key variables that drive the business? Every business has
two or three variables that matter most. Can you name them?
- Can you estimate what the business will look like in five years? Not with
precision, but with reasonable bounds.
2.2 The Research Hierarchy
Shearn recommends a specific order for research, designed to eliminate unsuitable
investments quickly before investing significant time:
- Quick screen (30 minutes). Read the most recent annual report summary, check
basic valuation metrics, verify that the business is within your competence.
Eliminate obviously unsuitable candidates.
- Business understanding (2-4 hours). Read annual reports for the last five
years. Understand the business model, competitive position, and industry dynamics.
- Management evaluation (2-4 hours). Study management's track record, capital
allocation history, compensation, and insider ownership.
- Financial deep dive (4-8 hours). Analyze earnings quality, balance sheet,
cash flow, and historical financial performance.
- Valuation (2-4 hours). Estimate intrinsic value using multiple approaches.
- Risk assessment (1-2 hours). Identify what could go wrong and assess whether
the margin of safety compensates for identified risks.
Total: 10-20 hours per investment. This is the minimum for a serious investment
decision. Anything less is speculation disguised as analysis.
3. Understanding the Business
3.1 Core Business Questions
The most fundamental requirement of any investment is understanding what the
business actually does. Shearn frames this with a series of questions:
What does the business do?
- Describe the business in one paragraph. What product or service does it provide?
To whom? At what price? Through what channel?
- What is the value proposition? Why do customers choose this company over
alternatives?
How has the business evolved?
- What did the business look like five years ago? Ten years ago?
- Has the core business remained stable, or has it changed significantly?
- Were the changes driven by strategic vision or by reaction to competitive pressure?
What is the industry structure?
- How many competitors exist? Are there two dominant players or two hundred?
- Is the industry consolidating or fragmenting?
- What is the industry growth rate? Is it accelerating or decelerating?
- Is the industry cyclical or stable?
- What is the regulatory environment? Is it likely to change?
3.2 The One-Paragraph Test
Shearn recommends that after completing initial research, the investor should be
able to write a single paragraph that captures:
- What the business does and for whom.
- The key competitive advantage.
- The primary driver of future growth.
- The biggest risk.
If you cannot write this paragraph clearly and confidently, you do not understand
the business well enough to invest. Return to the research phase or move on to
a different investment candidate.
4. Revenue Sources and Business Model
4.1 Revenue Decomposition
Understanding exactly where revenue comes from is essential:
- By product/service. What percentage of revenue comes from each product line
or service category? Is revenue concentrated in one product or diversified?
- By customer segment. Who are the major customer categories? Are they
consumers, businesses, or governments?
- By geography. What percentage of revenue is domestic vs. international?
What are the growth rates in each geography?
- By pricing model. Is revenue transactional (one-time) or recurring
(subscription, maintenance contracts, consumables)? Recurring revenue is
far more valuable than transactional revenue because it is more predictable
and more resistant to economic downturns.
4.2 Business Model Durability
The investor must assess whether the business model is durable:
- What is the switching cost for customers? High switching costs create
recurring revenue and pricing power. Low switching costs mean constant
competitive vulnerability.
- Is the product a small fraction of the customer's total cost but critical
to their operations? This is the ideal pricing position β the customer will
not spend time shopping for alternatives on a trivial expense.
- Are there network effects? Does the product become more valuable as more
people use it? Network effects create powerful moats.
- Is there a regulatory barrier? Licenses, patents, or regulatory approvals
that limit competition.
4.3 Revenue Quality Assessment
Not all revenue is created equal:
| Revenue Characteristic |
Higher Quality |
Lower Quality |
| Recurrence |
Subscription, long-term contracts |
Project-based, one-time |
| Visibility |
Backlog, contracted |
Depends on new orders |
| Customer concentration |
Diversified across many customers |
Few large customers |
| Geographic diversification |
Multiple markets |
Single market |
| Pricing power |
Can raise prices without losing volume |
Price-taker |
| Counter-cyclicality |
Non-discretionary spending |
Discretionary |
5. Competitive Dynamics and Moat Analysis
5.1 Porter's Five Forces Applied
Shearn incorporates competitive analysis into the checklist:
- Threat of new entrants. What prevents new competitors from entering? Capital
requirements, brand loyalty, regulatory barriers, economies of scale, network
effects?
- Bargaining power of suppliers. Can suppliers raise prices or restrict supply?
Is the company dependent on a single supplier?
- Bargaining power of buyers. Can customers demand lower prices or better
terms? Is the company dependent on a few large customers?
- Threat of substitutes. Are there alternative products or services that could
replace what the company offers?
- Competitive rivalry. How intense is competition among existing players?
Is competition primarily on price (bad) or on differentiation (better)?
5.2 Identifying the Moat
The economic moat is the sustainable competitive advantage that protects the
company's profitability. Shearn identifies several types:
- Brand. Consumers pay premium prices for the brand (Coca-Cola, Apple).
Test: Can the company raise prices without losing meaningful volume?
- Switching costs. Customers are locked in by high costs of switching
(enterprise software, banking relationships). Test: What is the customer
retention rate?
- Network effects. The product becomes more valuable with more users
(Visa, social networks). Test: Does user growth accelerate with scale?
- Cost advantage. The company can produce at lower cost than competitors
(Walmart's logistics, low-cost airlines). Test: Are gross margins sustainably
above competitors?
- Intangible assets. Patents, licenses, regulatory approvals that bar
competition (pharmaceutical patents, broadcasting licenses).
5.3 Moat Durability
Identifying a moat is not sufficient β the investor must assess its durability:
- Is the moat widening or narrowing? Look at trends in market share, pricing
power, and return on capital.
- What are the biggest threats to the moat? Technology disruption, regulatory
change, new business models?
- Has management demonstrated awareness of the moat and commitment to its
maintenance?
6. Customer Concentration and Relationships
6.1 The Customer Concentration Risk
One of the most frequently overlooked risks in stock analysis is customer
concentration. Shearn emphasizes this with specific thresholds:
- If one customer represents more than 10% of revenue, the investor must
understand that relationship deeply. What is the contract term? What are
the renewal prospects? What alternatives does the customer have?
- If one customer represents more than 25% of revenue, this is a material
risk. The loss of that customer could devastate the company.
- If the top five customers represent more than 50% of revenue, the company
is essentially a supplier, not a business with pricing power.
6.2 Customer Relationship Assessment
Beyond concentration, the quality of customer relationships matters:
- How long has the customer been buying? Long-standing relationships suggest
satisfaction and switching costs.
- Is the product mission-critical or discretionary? Mission-critical products
are rarely cut even in downturns.
- Who makes the purchasing decision? A procurement department focused on cost
is a different dynamic than an end-user who values functionality.
- Is the customer growing or shrinking? A growing customer expands the
addressable market; a shrinking one contracts it.
7. Evaluating Management β Character
7.1 Why Management Matters
Shearn argues that management quality is the most important and most neglected
dimension of stock analysis. Financial statements tell you where the business
has been; management determines where it is going.
7.2 Integrity Indicators
The most important management characteristic is integrity β does management
tell the truth and act in shareholders' interests?
Positive indicators:
- Management discusses mistakes openly in annual reports.
- Projections and guidance are realistic, not consistently overoptimistic.
- Management underpromises and overdelivers.
- The annual letter focuses on the business, not on excuses.
- Management avoids blaming external factors for poor results.
Red flags:
- Frequent changes in accounting methods or non-GAAP metrics.
- Excessive use of "adjusted" earnings that always exceed GAAP earnings.
- Aggressive revenue recognition practices.
- Large gap between reported earnings and cash flow from operations.
- Frequent restructuring charges presented as "one-time."
- CEO surrounded by yes-men (entire board is friends or business associates).
7.3 Competence Indicators
Beyond integrity, management must be competent:
- Track record. Has management delivered on past commitments? Compare what
management said three years ago with what actually happened.
- Industry knowledge. Does management demonstrate deep understanding of the
industry, or are they generic "professional managers"?
- Adaptability. Has management navigated industry disruptions or downturns
successfully?
- Succession planning. Is there a clear succession plan? Over-reliance on a
single individual is a risk.
8. Evaluating Management β Capital Allocation
8.1 The CEO as Capital Allocator
Shearn, following Buffett, argues that the CEO's most important job is capital
allocation β deciding how to deploy the cash the business generates. Options
include:
- Reinvesting in the business. Organic growth through capital expenditure,
R&D, or working capital investment.
- Acquisitions. Buying other businesses.
- Paying dividends. Returning cash to shareholders.
- Repurchasing shares. Buying back the company's own stock.
- Paying down debt. Reducing leverage.
8.2 Evaluating Each Option
Organic reinvestment: The best option when the business can earn high returns
on incremental capital. Check: What is the return on invested capital (ROIC)?
Is it above the cost of capital? Is it increasing or decreasing?
Acquisitions: The most dangerous option because CEOs systematically overpay.
Check: What has been the track record of past acquisitions? Was goodwill
written down subsequently? Did the acquired business grow after acquisition?
The best acquirers are disciplined, infrequent buyers who integrate carefully.
Dividends: Appropriate when the business cannot reinvest at attractive returns.
Check: Is the payout ratio sustainable? Is the dividend growing with earnings?
Share repurchases: The best option when the stock is undervalued. The worst
option when the stock is overvalued. Check: At what valuations has management
repurchased in the past? Did they buy when the stock was cheap or when it was
expensive? Many companies buy back stock primarily to offset dilution from
stock-based compensation β this is not capital allocation, it is compensation.
Debt reduction: Appropriate when leverage is excessive or when better options
are not available. Check: What is the debt-to-EBITDA ratio? Is it trending
in the right direction?
8.3 The Capital Allocation Scorecard
Rate management on a scale of 1-5 across each dimension:
| Dimension |
Score (1-5) |
| ROIC vs. cost of capital |
|
| Acquisition track record |
|
| Dividend sustainability |
|
| Buyback timing (at low vs. high prices) |
|
| Balance sheet management |
|
| Total |
Out of 25 |
Scores below 15 indicate poor capital allocation. Scores above 20 indicate
excellence. Very few management teams score above 20.
9. Insider Ownership and Compensation
9.1 Insider Ownership β Alignment Check
Insider ownership is the single most reliable indicator of management-shareholder
alignment:
- Meaningful ownership = meaningful alignment. If the CEO's net worth is
heavily concentrated in the company's stock, their economic interests are
aligned with shareholders.
- Token ownership = token alignment. If the CEO owns 0.1% of the company
while earning $20 million in annual compensation, the stock price is largely
irrelevant to their wealth.
9.2 What to Look For
Positive indicators:
- CEO owns at least 3-5% of the company (or the equivalent in market value,
for very large companies).
- Other senior executives and board members have meaningful personal investments.
- Management has been buying in the open market (not just receiving grants).
- Management holds shares for extended periods rather than selling at the
first opportunity.
Red flags:
- CEO sells large amounts of stock regularly while publicly promoting the company.
- Stock-based compensation is the primary form of insider "ownership."
- Management exercises options and sells immediately.
- Insider selling accelerates before bad news is disclosed.
9.3 Compensation Analysis
Management compensation should be structured to reward long-term value creation:
- Base salary should be reasonable, not extravagant. Excessive base salaries
indicate a board that is not negotiating on behalf of shareholders.
- Incentive compensation should be tied to long-term metrics. ROIC, free cash
flow growth, and total shareholder return over 3-5 years are good metrics.
Quarterly EPS targets are poor metrics that encourage manipulation.
- Options vs. restricted stock. Restricted stock with long vesting periods
aligns interests better than options because options reward only upside (and
can be repriced if the stock falls).
- Total compensation relative to peers. Is the CEO paid more or less than
similarly situated peers? Wide premiums require justification.
10. Financial Analysis β Earnings Quality
10.1 The Earnings Quality Spectrum
Not all reported earnings are real. Shearn emphasizes the critical distinction
between high-quality and low-quality earnings:
High-quality earnings are:
- Backed by cash flow. Operating cash flow consistently exceeds net income.
- Based on conservative accounting. Revenue is recognized when earned, expenses
when incurred.
- Recurring. Derived from ongoing business operations, not one-time events.
- Organic. Driven by volume growth or pricing power, not acquisitions.
Low-quality earnings are:
- Unbacked by cash flow. Net income consistently exceeds operating cash flow.
- Based on aggressive accounting. Revenue recognition stretched, expenses deferred.
- Non-recurring. Driven by gains on asset sales, tax adjustments, or accounting
changes.
- Acquisitive. Growth driven by serial acquisitions that mask organic weakness.
10.2 Earnings Quality Tests
- Cash flow comparison. Operating cash flow / net income should be 1.0x or
higher over a rolling five-year period. Ratios consistently below 1.0x are
a major red flag.
- Accrual analysis. High accruals (net income minus cash from operations)
relative to total assets suggest aggressive accounting.
- Receivables growth vs. revenue growth. If receivables grow faster than
revenue, the company may be stuffing the channel or extending credit to
dubious customers.
- Inventory growth vs. revenue growth. If inventory grows faster than revenue,
the company may be overproducing to absorb fixed costs, a sign of weakening
demand.
- Deferred revenue. Growing deferred revenue is a positive indicator β it
represents cash received for services not yet delivered.
- Goodwill and intangibles. A rapidly growing goodwill balance means the
company is making acquisitions. Has goodwill been impaired? If not, should it
have been?
10.3 Adjusted Earnings β Skepticism Required
When management presents "adjusted" earnings, the investor should ask:
- What specifically is being adjusted out? Are the adjustments genuinely one-time,
or do they recur every year?
- Does the adjustment increase or decrease reported earnings? (Almost always
increases β suspiciously.)
- Would the investment case change if only GAAP earnings were considered?
11. Financial Analysis β Balance Sheet Strength
11.1 The Balance Sheet as Safety Net
The balance sheet determines whether a company can survive adversity. A strong
balance sheet provides the optionality to:
- Weather economic downturns without distress.
- Make acquisitions when competitors are weakened.
- Invest in growth when others are retrenching.
- Avoid the forced selling and dilutive financing that destroy shareholder value.
11.2 Key Balance Sheet Metrics
Leverage:
- Debt-to-EBITDA ratio: below 2x is conservative; above 4x is aggressive.
- Interest coverage: EBIT/interest expense should exceed 5x for comfort.
- Debt-to-equity: context-dependent, but rising leverage is a warning sign.
Liquidity:
- Current ratio: above 1.5x provides a reasonable buffer.
- Quick ratio: above 1.0x ensures the company can meet obligations without
selling inventory.
- Cash and equivalents relative to near-term maturities.
Off-balance-sheet obligations:
- Operating leases (now largely on-balance-sheet under new accounting standards).
- Pension obligations (funded status, discount rate assumptions).
- Contingent liabilities (litigation, environmental, guarantees).
11.3 Balance Sheet Red Flags
- Debt covenants that could be violated in a downturn.
- Near-term debt maturities that require refinancing.
- Goodwill exceeding 50% of total assets (acquisition-dependent strategy).
- Negative tangible book value (potentially illiquid in distress).
- Rapidly growing debt without corresponding asset growth.
12. Financial Analysis β Cash Flow
12.1 Cash Flow Is King
Shearn, following a long tradition in value investing, argues that cash flow
is the single most reliable measure of financial performance because it is the
hardest to manipulate:
- Earnings can be managed through accounting choices. Revenue recognition,
depreciation methods, reserve adjustments, and classification of expenses all
allow management to present a favorable picture.
- Cash flow is factual. Either cash came in or it didn't. Either cash went
out or it didn't.
12.2 Free Cash Flow Analysis
Free cash flow (FCF) = Operating cash flow minus capital expenditures.
This is the cash available to shareholders after maintaining the business. Key
questions:
- Is FCF positive and growing? A business that consistently generates FCF is
self-funding. A business that consistently burns cash must raise capital.
- Is FCF higher or lower than reported earnings? Higher is better β it means
earnings are backed by cash. Lower suggests aggressive accounting.
- What is the FCF yield? FCF / market capitalization. A high FCF yield
combined with a low P/E suggests high-quality earnings.
- What is the capex breakdown? Distinguish maintenance capex (necessary to
maintain current operations) from growth capex (investment in expansion).
Only maintenance capex should be subtracted to calculate owner earnings.
12.3 Cash Flow Conversion Rates
The ultimate test of earnings quality:
| Metric |
Target |
Red Flag |
| Operating CF / Net Income |
> 1.0x |
< 0.8x |
| FCF / Net Income |
> 0.7x |
< 0.5x |
| FCF / Operating CF |
> 0.5x |
< 0.3x (capex-intensive) |
| FCF Yield |
> 5% |
< 2% at premium valuation |
13. Valuation Framework
13.1 Multiple Approaches Required
Shearn advocates using multiple valuation approaches and triangulating:
- Discounted cash flow (DCF). Estimate future free cash flows and discount
at an appropriate rate. The most theoretically sound but most sensitive to
assumptions.
- Earnings multiples. Compare P/E, EV/EBITDA, and P/FCF to historical averages
and peer companies. Simple and intuitive but can be misleading if current
earnings are abnormal.
- Asset-based valuation. Relevant for asset-heavy businesses (banks, real
estate, natural resources). Compare price to book value or net asset value.
- Comparable transactions. What have similar businesses been acquired for?
This provides a private market value estimate.
13.2 The Margin of Safety
The gap between estimated intrinsic value and current price is the margin of
safety. Shearn recommends:
- Minimum 25-30% discount to estimated intrinsic value for high-quality
businesses with predictable cash flows.
- Minimum 40-50% discount for lower-quality or more cyclical businesses.
- Wider margin for less certain estimates. The less confident you are in your
valuation, the larger the margin of safety you should require.
13.3 Valuation Discipline
- Never stretch to justify a purchase. If the math doesn't work at a reasonable
set of assumptions, walk away.
- Remember that valuation is an art, not a science. Precision is illusory.
- The best investments are obvious bargains that require no spreadsheet gymnastics.
14. The Complete Checklist
14.1 Business Understanding (10 Questions)
14.2 Management Evaluation (10 Questions)
14.3 Financial Analysis (10 Questions)
14.4 Valuation (5 Questions)
15. Common Mistakes
15.1 Errors of Omission (Not Checking)
- Skipping management evaluation. Investors who focus exclusively on
financial metrics and ignore management quality are missing the most important
predictor of future performance.
- Ignoring customer concentration. The loss of a major customer can be
devastating, and this risk is often hidden in footnotes.
- Not reading the footnotes. Critical information about accounting policies,
contingent liabilities, and off-balance-sheet obligations is buried in footnotes.
- Failing to check the cash flow statement. Relying on the income statement
alone is an invitation to be deceived by accounting manipulation.
15.2 Errors of Commission (Checking Wrongly)
- Anchoring to the current price. Starting with the price and building a
case to justify it, rather than starting with fundamentals and determining
what the business is worth.
- Using only one valuation method. Any single valuation method can be gamed
by choosing favorable assumptions.
- Trusting management's adjusted metrics. Non-GAAP earnings, "normalized"
results, and pro forma figures are management's version of reality, not
reality itself.
- Ignoring cyclicality. Valuing a cyclical business based on peak earnings
produces a dramatic overvaluation.
15.3 Errors of Temperament
- Falling in love with the story. A compelling narrative can blind investors
to fundamental weaknesses.
- Confirmation bias after purchase. Once you own a stock, you will tend to
seek information that confirms your thesis and dismiss information that
contradicts it. The checklist should be revisited periodically, not just
at the time of purchase.
- Impatience. Abandoning the research process because you feel pressure to
deploy capital. Shearn argues that the quality of research directly determines
the quality of investment outcomes.
- Checking the box without thinking. A checklist is only as good as the
thought behind each answer. Going through the motions is worse than not
having a checklist because it creates false confidence.
17. Key Quotes
"The checklist is not a substitute for thought. It is a tool to ensure that
thought is applied to every important dimension of the investment decision."
"The greatest investment mistakes I've made have all been errors of omission β
things I didn't check, questions I didn't ask, risks I didn't consider."
"If you cannot explain the business to a ten-year-old, you do not understand
it well enough to invest in it."
"Management quality is the most important factor in long-term investment success
and the one most frequently overlooked."
"Cash flow is fact. Earnings are opinion."
"The single most important question you can ask about a company is: What is
the return on invested capital, and is it higher or lower than the cost of
capital?"
"A checklist ensures that in moments of excitement or panic, you do not skip
the steps that protect you from your own worst instincts."
"The margin of safety is not a luxury. It is the difference between investing
and speculating."
"The best investment processes are the ones that feel tedious and boring.
If your process is exciting, you are probably doing it wrong."
"Customer concentration is a risk that hides in plain sight. Many investors
never bother to check who the company's largest customers are, yet the loss
of a single customer can destroy years of earnings."
"The most important page in the annual report is not the income statement.
It is the cash flow statement. The income statement tells you what management
wants you to believe. The cash flow statement tells you what actually happened."
This specification systematizes Michael Shearn's checklist-based approach to
stock analysis. The core principle is that investment mistakes are overwhelmingly
errors of omission β failures to check what should have been checked. By
imposing a rigorous, repeatable process on the research phase, the checklist
ensures that no critical dimension is overlooked, regardless of the investor's
emotional state or time pressure. The checklist does not replace judgment; it
ensures that judgment is applied to the right questions in the right order.
