Bayesian Intrinsic Growth Valuation
Core Principle
Do not classify company news as simply bullish or bearish. Translate every company-specific data point into a probability update for future 3-5 year revenue growth, margin, TAM, market share, valuation multiple, and market sentiment.
The goal is to estimate the company's true intrinsic growth speed and compare it with the growth already implied by the current market value.
Treat outputs as research hypotheses, not personalized investment advice. Verify current market cap, price, revenue, margins, filings, guidance, peer multiples, and news from reliable current sources before making time-sensitive claims.
Required Inputs
Use whatever the user provides, and clearly mark missing variables that require verification:
- company fundamentals: revenue scale, margins, free cash flow, ROIC, balance sheet, customers, moat, pricing power
- industry cycle: demand growth, supply-demand gap, inventory cycle, order cycle, price trends, policy, downstream capex
- revenue and growth: historical growth, guidance, backlog, book-to-bill, organic growth, ASP, shipment volume
- TAM and TAM growth: current TAM, future TAM CAGR, penetration, market share, new market expansion
- valuation: EV/Sales, EV/EBITDA, P/E, FCF yield, PEG, historical percentile, peer percentile, implied growth
- share-price trend: 1M/3M/6M/12M and post-earnings returns, drawdown/rebound path, volatility, volume, relative performance versus sector/index, and whether price appreciation is ahead of intrinsic growth
- market FOMO: share-price move, options activity, social heat, analyst revisions, theme crowding, narrative strength
- new information: orders, customers, products, pricing, policy, competition, capacity, earnings, management guidance
Optional SEC Data Assist
For U.S.-listed companies, use SEC filings as the baseline evidence for reported historical fundamentals. edgartools can be used to fetch company filings, XBRL financial statements, filing text, insider transactions, ownership filings, and recent 8-K disclosures.
If the environment does not already have it, install with pip install edgartools or uv pip install edgartools. The import package is edgar, not edgartools. SEC access requires an identity; set EDGAR_IDENTITY="Name email@example.com" in the environment or call from edgar import set_identity; set_identity("name@example.com") before requests.
Minimal usage pattern:
from edgar import Company
company = Company("AAPL")
financials = company.get_financials()
income = financials.income_statement()
balance = financials.balance_sheet()
cashflow = financials.cashflow_statement()
Use SEC data to anchor:
- revenue history, gross margin, operating margin, EPS, free cash flow, capex, debt, cash, dilution, and share-count trends
- segment revenue, customer concentration, backlog/order language, risk-factor changes, and management's stated demand drivers
- 10-K and 10-Q trend baselines for the prior, and 8-K/earnings-release data for the latest update
- Form 4, 13D/G, and 13F data as sentiment/ownership context only, not as intrinsic-growth evidence by itself
Do not use SEC data as a substitute for current market data, consensus estimates, forward multiples, TAM estimates, option activity, or real-time price movement. If using edgartools or SEC filings, name the form and filing date, and separate "reported fact" from "analyst/market estimate."
Growth Hypotheses
Always frame future 3-5 year revenue CAGR as probabilities across these hypotheses:
| Hypothesis | Label | 3-5Y revenue CAGR |
|---|
| H0 | contraction | <0% |
| H1 | mature slow growth | 0%-5% |
| H2 | steady growth | 5%-12% |
| H3 | high-cycle growth | 12%-25% |
| H4 | structural breakout | 25%-50% |
| H5 | platform expansion | >50% |
Workflow
1. Establish The Prior
Assign initial probabilities to H0-H5 using fundamentals, industry cycle, TAM, historical growth, and competitive position.
Prefer a conservative prior when evidence is incomplete. Do not let market excitement alone justify H4 or H5.
2. Classify New Information By Variable
When new information appears, identify which variables it affects:
- revenue growth
- margin
- TAM
- market share
- competitive structure
- cash flow
- valuation multiple
- FOMO sentiment
If information mainly affects market attention, update valuation multiple and FOMO, not intrinsic growth.
3. Bayesian Update
Ask how likely the new information is under each growth hypothesis:
- If the information is more consistent with H3/H4/H5, raise those probabilities.
- If it looks cyclical, one-off, or backlog timing, avoid over-updating long-term growth.
- If it only strengthens narrative or trading enthusiasm, raise FOMO and multiple risk rather than intrinsic growth.
- If it contradicts high growth, shift probability toward H0-H2.
Show the update as prior -> likelihood interpretation -> posterior.
4. Calculate Weighted Intrinsic Growth
Estimate weighted intrinsic 3-5 year revenue CAGR from the posterior probabilities. Use midpoint assumptions unless better evidence is available:
| Hypothesis | Suggested midpoint |
|---|
| H0 | -5% |
| H1 | 2.5% |
| H2 | 8.5% |
| H3 | 18.5% |
| H4 | 37.5% |
| H5 | 60% or scenario-specific |
Report a range, not false precision.
5. Reverse-Engineer Market-Implied Growth
Infer the growth rate embedded in current valuation using market cap or enterprise value, revenue, margin, FCF margin, valuation multiple, and discount-rate assumptions.
If exact data is unavailable, state the missing inputs and provide a qualitative implied-growth bracket instead of inventing numbers.
6. Compare Intrinsic Growth With Implied Growth
Classify valuation state:
| Comparison | Valuation state |
|---|
| intrinsic growth > implied growth | undervalued |
| intrinsic growth roughly equals implied growth | fair value |
| implied growth > intrinsic growth, but cycle still accelerating | expensive but tradable |
| implied growth far above intrinsic growth and FOMO is extreme | bubble-like |
7. Measure Price-Growth Divergence
Separately judge whether the share-price trend has moved faster or slower than the intrinsic-growth update.
Use current data where possible:
- compare recent share-price return, market-cap expansion, and multiple expansion with changes in revenue CAGR, guidance, backlog, margins, and posterior probabilities
- separate rerating driven by fundamentals from rerating driven by liquidity, theme crowding, short squeeze, index flows, or FOMO
- classify the divergence as
price lagging fundamentals, price aligned with fundamentals, price ahead of fundamentals, or severe price-growth divergence
- when price is ahead of intrinsic growth, reduce confidence in long-term margin of safety even if the company remains high quality
- when price lags intrinsic growth, identify the catalyst needed for the market to close the gap
Suggested qualitative thresholds:
| Price move versus intrinsic-growth update | Divergence signal |
|---|
| price return materially below improved posterior growth / implied growth still below intrinsic growth | price lagging fundamentals |
| price return and multiple expansion roughly match posterior growth improvement | aligned |
| price return or multiple expansion exceeds posterior growth improvement | price ahead of fundamentals |
| rapid price rise, multiple rerating, and little/no posterior intrinsic-growth improvement | severe divergence / FOMO risk |
8. Build A Verification Path
Define the time window and concrete indicators that will validate or falsify the model:
- revenue growth and guidance revisions
- backlog, book-to-bill, orders, lead times
- ASP, shipment volume, utilization, capacity expansion
- gross margin, operating leverage, FCF conversion
- TAM expansion evidence and penetration change
- market-share gain or loss
- peer/customer/supplier corroboration
- analyst revision breadth and narrative crowding

Style Rules
- Start from observable demand changes, not surface narrative.
- Translate demand into revenue, profit, TAM, and valuation impact.
- Look for underpriced shovels, bottlenecks, second-position winners, hard manufacturing, and critical supply-chain nodes.
- Separate intrinsic growth updates from FOMO and multiple expansion.
- Explicitly measure whether share-price movement is leading, matching, or lagging the intrinsic-growth update.
- Distinguish structural growth from cyclical rebound or one-time order timing.
- State uncertainty, missing data, and falsification conditions clearly.
