Business Quality Assessment
Economic Moat Analysis
Wide Moat (durable 20+ year advantage):
Network Effects: More users = more valuable (Visa, Meta, Airbnb)
Cost Advantages: Structural lower costs (Costco, Amazon AWS)
Switching Costs: Painful to leave (Salesforce, Adobe, Oracle)
Intangible Assets: Brand, patents, licenses (Apple, Pfizer, Disney)
Efficient Scale: Natural monopoly in niche market (railroads, utilities)
Narrow Moat:
Some competitive advantage but less durable
1-10 year sustainable edge
No Moat:
Commodity business, easy to replicate
Price competition, low margins
Management Quality Checklist
Capital Allocation:
[ ] ROIC consistently above WACC (creating value)
[ ] Buybacks done when stock is CHEAP (not just because)
[ ] Acquisitions at reasonable prices with clear rationale
[ ] Dividends sustainable with FCF coverage
Shareholder Alignment:
[ ] Insider ownership > 5% (skin in the game)
[ ] Compensation tied to long-term metrics not just EPS
[ ] Honest communication (admits mistakes, no spin)
[ ] Low executive turnover at senior level
Red Flags:
[ ] Frequent accounting restatements
[ ] CFO or auditor changes
[ ] Related party transactions
[ ] Aggressive revenue recognition
[ ] Constantly missing guidance then blaming macro

Reading Earnings Reports
Key items to check in every earnings release:
1. Revenue vs estimate (beat/miss and magnitude)
2. EPS vs estimate (GAAP and non-GAAP)
3. Gross margin trend (expanding or compressing?)
4. Forward guidance (raised, maintained, or lowered?)
5. Management commentary on demand environment
6. Free cash flow vs net income (earnings quality)
7. Share count changes (dilution or buybacks?)
8. Balance sheet changes (cash, debt, inventory)
Sector-Specific Metrics
Technology / SaaS:
ARR / MRR -> Annual/Monthly Recurring Revenue
NRR -> Net Revenue Retention (>120% = excellent)
CAC / LTV -> Customer Acquisition Cost vs Lifetime Value
Rule of 40 -> Revenue growth % + FCF margin % > 40
Banking / Financial:
NIM -> Net Interest Margin
NPL Ratio -> Non-Performing Loans / Total Loans
CET1 Ratio -> Core capital adequacy ratio
Efficiency Ratio-> Non-interest expense / revenue (lower = better)
Retail:
Same-Store Sales-> Organic growth ex new store openings
Inventory Turns -> COGS / Average Inventory
Sales per sq ft -> Revenue efficiency metric
Real Estate (REITs):
FFO -> Funds From Operations (earnings proxy)
AFFO -> Adjusted FFO (capex adjusted)
Cap Rate -> NOI / Property Value
Occupancy Rate -> % of space leased

Common Pitfalls
| Pitfall | Problem | Fix |
|---|---|---|
| Trusting EPS alone | Easily manipulated | Focus on FCF and cash conversion |
| Ignoring debt | Hidden risk | Check net debt and interest coverage |
| Overpaying for growth | Even great companies can be bad investments | Margin of safety always |
| Recency bias | Last 2 years seem like forever | Analyze full business cycle (10 years) |
| Ignoring moat erosion | Moat can shrink | Re-evaluate thesis annually |
| Single metric valuation | P/E alone is incomplete | Use multiple valuation methods |
| Not reading footnotes | Key risks hidden there | Always read 10-K footnotes |
Best Practices
- Read the 10-K first — management discussion, risk factors, footnotes
- Follow the cash — FCF is harder to fake than net income
- Understand the business — if you cannot explain it simply, do not invest
- Margin of safety always — even great businesses need a good price
- Think in decades — short-term noise vs long-term compounding
- Track your thesis — write down why you bought, review regularly
- Compare to alternatives — always ask: is this the best use of capital?
