Free Data, Durable Edges: Finding Moats and Compounders
Today we explore using free data sources to research moats and compounding businesses, turning public filings, open macro databases, and alternative digital breadcrumbs into practical insight. You will learn how to translate facts into conviction, build repeatable workflows, and spot durable edges without expensive tools. Expect concrete examples, transparent calculations, and habits that protect you from noise while sharpening judgment for long-term ownership decisions.
Start With the Edge: What a Moat Looks Like in the Numbers
Before crunching numbers, anchor your intuition in what an enduring edge really is: sustained excess returns supported by structures that competitors cannot cheaply copy. We will map typical sources of defensibility, show how they appear in accessible datasets, and outline warning signs that masquerade as strength. With clarity on definitions, every later metric becomes more meaningful and harder to misinterpret.
Economic layers that defend cash flows
Look for protective layers stacking upon one another: privileged distribution, proprietary data, regulatory permissions, habitual workflows, and brand trust that lowers perceived risk. When these accumulate, cash flows become smoother through shocks, and reinvestment decisions face fewer competitive bids, preserving favorable unit economics over many cycles.
Compounding flywheels and reinvestment runways
Compounding requires not only attractive projects but also the freedom and discipline to fund them repeatedly. Seek rising reinvestment rates at strong incremental returns, feedback loops from scale or learning, and cultural signals in letters or transcripts that prioritize customer outcomes, talent density, and product velocity over quarterly theatrics.
Separating narrative from measurable advantage
Stories inspire, yet persistence shows up as numbers behaving well over time. Cross-check claims against segment disclosures, cohort retention, gross margin stability, and capital turns. Prefer facts you can re-create from filings, and downgrade assertions that never intersect measurable customer behavior or repeatable cash conversion.
Hunting Grounds: Free Sources You Can Trust
Reliable insight starts with sources that anyone can open and verify. Combine SEC EDGAR, SEDAR+, Companies House, and investor relations archives with FRED, OECD, and World Bank series. Layer in transcripts, conference presentations, and open alternative signals like app reviews, job postings, patent databases, search interest, and web traffic estimates to triangulate traction without paying a cent.
Filings and transcripts without paywalls
Start with 10-Ks, 20-Fs, MD&A, and proxy statements for governance and incentives. Add quarterly 10-Qs and earnings call transcripts to catch momentum or caution. Bookmark company presentations, segment restatements, and accounting policy notes, which often reveal unit economics and capital allocation priorities more clearly than glossy marketing decks or media interviews.
Macroeconomic and industry baselines
Context matters. Use FRED for rates, spreads, and employment, OECD for cross-country comparables, and World Bank development data for penetration curves. Blend these with regulator publications and trade group statistics to normalize cycles, separate secular drivers from temporary shocks, and calibrate expectations for pricing power, growth ceilings, and capital intensity.
Alternative breadcrumbs that hint at traction
Scrape or manually sample app store reviews, developer forum activity, Github stars, LinkedIn hiring patterns, and Glassdoor comments to gauge momentum and switching friction. Cross-reference Google Trends, Patent Public Search, and free web traffic panels, always looking for consistent, multi-source confirmation rather than exciting, isolated spikes that mislead.
Quant Signals That Endure: ROIC, Reinvestment, and Unit Economics
The best businesses turn each dollar kept into more dollars earned, repeatedly and predictably. Measure return on invested capital, its incremental form, and the portion of cash reinvested at attractive yields. Track free cash flow per share, gross margin resilience, cash conversion, and inventory turns, ensuring calculations tie directly back to audited, publicly available statements.
User behavior breadcrumbs hiding in plain sight
Scrutinize churn signals in disclosed cohort tables, support backlog commentary, and renewal timing hints hidden within revenue recognition footnotes. Pair those with app reviews mentioning migration pain, training investment, or embedded workflows, because real switching costs rarely announce themselves loudly in marketing copy or finance slides.
Ecosystems, complements, and dependency signals
Observe the density of integrations, third-party extensions, and certifications. Track developer forum growth, GitHub pull requests, and marketplace transactions. Expanding complements usually indicate growing value for every participant, strengthening defense against entrants who must replicate not just a product, but relationships, tooling, and accumulated know-how across the ecosystem.
Pricing power without shouting about price
True leverage appears as resilient gross margins amid cost inflation, modest discounting through downturns, and willingness-to-pay evidenced by premium tiers or upsells. Cross-check with customer sentiment and competitive price sheets. Durable differentiation lets companies hold line quietly, while weaker peers over-signal affordability and chase volume at shrinking contribution.
Time as the Ultimate Judge: Longitudinal Testing of the Edge
Building clean time series from messy disclosures
Companies change segments, rename metrics, and tweak definitions. Create mapping tables, reconcile restatements, and annotate extraordinary items. Consistency beats precision when tradeoffs appear, so prioritize comparability. Publish your methods alongside results, enabling others to replicate the series and challenge assumptions where they might hide optimistic bias.
Visualizing durability with rolling windows and cohorts
Use rolling medians and trailing averages to reveal structural direction rather than headline spikes. Build new-customer cohorts and product-level retention curves, connecting behavior to revenue recognition. When plotted together, consistency across views gives confidence that advantage is sticky, not a lucky streak during an unusually forgiving macro backdrop.
Contextualizing anomalies before they mislead you
Outliers deserve investigation, not immediate celebration. Tie jumps to pricing changes, one-off contracts, tax credits, or accounting updates. Compare peers under identical conditions to avoid attributing weather to genius. If explanations fail, mark uncertainty explicitly and wait for confirmation rather than forcing a comforting, but fragile, narrative.
From Insight to Action: Build a Watchlist and Join the Conversation
Great research earns its keep when it shapes behavior. Translate findings into a living watchlist with crisp criteria, alerts, and prewritten reactions. Track catalysts, governance milestones, and reinvestment evidence. Share your dashboard, invite critique, and subscribe for updates, turning personal learning into a compounding, community-powered advantage over time.
Combine a spreadsheet model with EDGAR links, RSS feeds for filings, and calendar reminders around earnings and capital markets days. Add Google Alerts, FRED series, and open transcripts. A single tab consolidating signals reduces fatigue, preserves context, and nudges timely, disciplined responses instead of impulsive reactions.
Precommit to ranges where patience is rewarded, conditions that must hold, and behaviors you will abandon if evidence shifts. Document edge cases, maximum position sizes, and disqualifiers. Clear rules convert analysis into habits, lowering emotional tax during volatility while protecting bandwidth for fresh opportunities that truly compound.
