The economics should be explainable without hiding behind complexity.
Research method
Understand the business. Test the numbers. Value the evidence.
Harbor approaches each company as a prospective owner would: starting with its economics, testing whether reported results reflect economic reality, and asking what the current price already assumes.
What matters
Five questions before the spreadsheet gets complicated.
Complex models do not repair weak business economics. The first pass focuses on whether the company is understandable, durable, and capable of reinvesting owner capital well.
Reported growth matters less when each new dollar earns a weak return.
Competition, customer behavior, regulation, and substitution all test durability.
A long runway at attractive incremental returns is central to long-term value creation.
Retained earnings, acquisitions, debt, buybacks, and dividends are competing uses of owner capital.
From question to conclusion
A visible chain of reasoning.
The aim is not to remove uncertainty. It is to show where it sits, what would change the conclusion, and which risks deserve attention.
Scope
Define the decision, time horizon, depth, exclusions, and output before work begins.
Investigate
Build the economic picture from primary materials, operating evidence, and industry context.
Value
Test scenarios and compare the evidence with what the current price appears to require.
Deliver
Lead with the conclusion, economics, risks, and unresolved questions.
Financial statement analysis
Reported earnings are only the starting point.
Harbor applies forensic-level scrutiny to the financial statements without losing sight of the business. Reported earnings are tested against cash generation, balance-sheet strength, unit economics, and the capital required to sustain growth.
Reported earningsCash conversionReinvestment economicsOwner value
This is investment research, not an audit, assurance engagement, or fraud examination.
Earnings quality
Reconcile reported profit with cash flow, recurring economics, and adjusted measures.
Footnotes and judgments
Read policies, estimates, contingencies, related-party items, and changes that can alter the economic picture.
Balance-sheet resilience
Test liquidity, leverage, working capital, commitments, and the ability to absorb a difficult period.
Unit economics
Connect margins and returns to price, volume, mix, operating assets, and reinvestment needs.
The method serves the decision.
Depth and format depend on the mandate. The work may range from a focused question to a full company study, valuation, or ongoing thesis review.
