| description | Use when valuing a durable, high-ROIC LONG-RUNWAY COMPOUNDER — a proven franchise with a 10–20 year reinvestment runway (IGI, CAMS, the HUL/NESTLE/TITAN "forever-in-waiting" trio, consumer/franchise/platform compounders) — where a standard 5-year DCF would TRUNCATE the value and wrongly flag a wonderful business as overvalued. Provides multi-stage DCF, the growth = reinvestment × ROIC identity, growth/ROIC fade, terminal-value discipline, and the reverse-DCF "is this heroic?" check. This is the fix for the v2 machinery over-demoting genuine compounders on a too-short, guidance-anchored window. Triggers: "value this compounder", "long-runway DCF", "is the 5-yr DCF truncating this", grading a proven high-ROIC franchise.

Long-Runway DCF (the finance-desk "valuation analyst")
The diagnosed hole: the v2 IV step anchored to a ~5-year, management-guidance window with a
4.5% terminal — which undervalues genuine 10–20yr compounders (it demoted IGI iv-high 511→370,
CAMS to negative MoS). This skill corrects that without becoming a license to overpay — the
margin-of-safety + IRR-beats-Nifty gates still bind. The goal is to stop falsely demoting a
wonderful compounder, not to justify a heroic price.
STEP -1 — The false-precision gate (binding; run BEFORE any staging)
The binding CIO can veto the extended-window model itself. Before modelling, ask: is the value obvious
without a 15-year projection? If the buy case only survives at the far end of a 10–15yr forecast, the margin
of safety is a modelling artifact, not a fact (avoid-false-precision, invest-only-when-value-is-obvious,
beware-of-believing-your-own-projections; desk: [[extended-window-must-pass-the-false-precision-test]]).
A long runway is a reason not to truncate a value that is already compelling on conservative numbers — it is
not a tool to manufacture upside that isn't there on a 5–7yr view. If the case fails this gate, STOP: this
is a WATCH, and no amount of multi-stage machinery rescues it. Calibrate this as a veto on heroic far-window
cases only — not a rejection of disciplined multi-stage DCF for a genuinely obvious compounder.
STEP 0 — Pull the canon (binding-safe)
Damodaran's DCF/terminal-value method-atomics are in the canon layer:
set -a && source /Users/Dhiraj/dev/invest/.env && set +a && /Users/Dhiraj/dev/invest/.venv/bin/python \
/Users/Dhiraj/dev/invest/data/scripts/32_consult_brain.py \
--company "<name>" --model general --step intrinsic-value --corpus canon \
--json-out extracted/grilling/<TICKER>_dcf.json
If that returns 0 / thin principles (the valuation method-atomics aren't model-scoped, so a bare
company name can miss them), re-run with method terms appended to --company, e.g.
--company "<name> DCF terminal value reinvestment fade growth ROIC" — that reliably surfaces the
two/three-stage DCF, g=b×ROIC, terminal-value, and reverse-DCF atomics. Cite only returned slugs.
Also run the binding consult (Munger/Buffett CIO) for the moat-durability judgment that justifies
the runway. The canon is the method; the CIO is the judge of whether the runway is real.
Pull the moat-erosion atoms to CAP the explicit window — runway length is an output of the moat verdict,
not a free parameter ([[runway-length-equals-moat-durability]]). Add a moat consult on the conviction step
(which maps to the moat/management/owner-earnings filters), --corpus blended to surface the desk + canon moat
atomics alongside the binding CIO:
... 32_consult_brain.py --company "<name> moat durability erosion contestable pricing power" --model general --step conviction --corpus blended ...
moats-are-hard-to-maintain and fast-moats-can-be-lost-fast are the binding governors: a Wide+Widening moat
earns a long explicit window; a contestable/eroding one caps it short. The fade (METHOD §3) then competes the
excess returns away regardless.
WHEN this skill applies (the gate)
ONLY for a proven compounder: durable moat (binding CIO-confirmed), high & sustained ROIC
(≫ cost of capital), a real reinvestment runway, aligned long-horizon ownership. A 5-yr window is
correct for an ordinary business — do NOT extend the window for a contestable or commodity name.
Extending the runway is earned by moat durability, not assumed.
Bank / financial hand-off (STOP-gate). If the subject is a bank, NBFC, SFB, or insurer, this skill does
not apply — g = b × ROIC with FCFF is invalid when debt is raw material, not financing
(debt-as-raw-material-diagnostic). Route to bank-valuation, which values equity directly via the
excess-return / justified-P/B model (excess-return-model-for-equity-valuation). Do not free-hand a firm-DCF
on a financial.
METHOD — multi-stage DCF
- Fix the cash-flow object FIRST: it is OWNER EARNINGS — FCF to equity net of true maintenance capex,
not reported EPS or unadjusted FCF (
intrinsic-value-is-discounted-future-cash, focus-on-owners-earnings).
If you instead model FCFF, you MUST discount at WACC and never at Ke; equity cash flows discount at
Ke (match-cash-flows-and-discount-rates). A mismatched numerator/denominator silently corrupts the IV.
- Stage the model to the RUNWAY, not to guidance. Explicit high-growth period = the justified
runway (often 10–15yr for a proven compounder), then a fade/transition stage, then stable.
Anchoring iv to 5yr of guided growth is the error that demoted IGI/CAMS.
- Growth = reinvestment rate × ROIC (
g = b × ROIC; canon: fundamental-growth-rate-formula). This is
the load-bearing identity: the value of a compounder comes from reinvesting a high fraction at a high
ROIC, not from a high headline g. A franchise reinvesting 50% at 30% ROIC compounds intrinsic value
~15%/yr — and that is what a 5-yr window throws away. Model the reinvestment explicitly, and treat the
assumed reinvestment rate as a capital-allocation judgment, not a free dial
([[reinvestment-rate-is-a-capital-allocation-judgment]]): b is only credible if management actually has
the runway and discipline to deploy it above the cost of capital.
- FADE both growth AND ROIC toward the economy / cost of capital. Never extrapolate peak growth or
peak ROIC to perpetuity — excess returns get competed away. The fade is what keeps the extended
window honest.
- Terminal-value discipline.
TV = CF_{n+1} / (r − g) (canon: stable-growth-terminal-value-formula);
stable g ≤ risk-free rate ≤ economy growth (terminal-growth-rate-riskfree-rate-cap); terminal ROIC
fades toward cost of capital. The real TV guardrail is NOT a percentage cap. A high TV share is
expected for a true compounder and is not a reliability test
(terminal-value-percent-dcf-value-not-a-reliability-test; desk:
[[high-terminal-value-share-is-not-a-red-flag-for-a-compounder]]). What actually disciplines the terminal
value is (a) the reverse-implied-growth check (reverse-implied-growth-check, see SANITY CHECK below)
and (b) stable-period reinvestment = g / ROC consistency ():
the terminal g you assume must be funded by a terminal reinvestment rate the ROC can support. Get those two
right and the TV share takes care of itself.
THE SANITY CHECK (already in the machinery — keep it)
Reverse-DCF (canon: reverse-implied-growth-check): back out the growth the current price implies;
compare to demonstrated + plausibly-sustainable growth. If the price implies ≫ demonstrated (e.g. CAMS
implied 36.8% vs demonstrated 16%), it's heroic → no margin of safety, regardless of how good the
business is. The g-files (extracted/valuation/v2/g*.json) already do this; treat it as the
overpaying-guardrail. This — together with the g/ROC reinvestment-consistency check — is the guardrail that
replaces the old "TV >80% = trap" rule (which canon rejects as a reliability test).
THE BALANCE (the Munger caveat — do NOT skip)
Extending the explicit window raises IV — so it MUST be paired with:
- the conviction-scaled margin of safety (buy_below = iv_base × (1 − required_MoS)), and
- the IRR-beats-~10%-Nifty opportunity-cost gate.
A longer runway widens the IV range; it does not lower the MoS you demand. A wonderful compounder
at a heroic price is still a WATCH, not a BUY. The fix is don't falsely demote — not "pay anything."
OUTPUT (feeds the v2 machinery)
A conservative IV range (iv_low / iv_base / iv_high) from the multi-stage DCF, with the explicit-window
length, g-vs-ROIC reinvestment assumptions, fade path, and terminal g stated. sell = iv_high;
buy_below = iv_base × (1 − required_MoS). If the reverse-DCF says heroic, say so honestly.
Hard rules
- Pass the STEP -1 false-precision gate first: if the buy case only survives at the far end of a 10–15yr
projection, it's an artifact — WATCH, not BUY. Extend the window ONLY for a CIO-confirmed durable compounder
whose moat verdict earns it (
[[runway-length-equals-moat-durability]]); default to 5yr otherwise.
- Always fade growth AND ROIC; never perpetuity-extrapolate peak metrics.
- Stable terminal g ≤ risk-free (
terminal-growth-rate-riskfree-rate-cap). Do NOT use a fixed "TV >80% =
trap" rule — canon rejects TV-share as a reliability test (terminal-value-percent-dcf-value-not-a-reliability-test).
Discipline the terminal value with the reverse-implied-growth check + g/ROC reinvestment consistency
(reinvestment-rate-terminal-value-consistency) instead; a high TV share is normal for a real compounder.
- Always run the reverse-DCF heroic-check; the MoS + IRR gates still bind. For India, model the longer window
AND the higher country-risk discount rate both ways and demand a larger MoS — the net effect is not
assumed positive (the extended-India-window itself is an acknowledged ungrounded gap).
- Cite only canon slugs the consult returns; the binding CIO judges the moat that earns the runway. If the
subject is a bank/financial, STOP and use
bank-valuation. Desk atomics (vault/desk/valuation/atomic/…)
are referenced via [[slug]] as connective tissue — they are not authored or edited here, and perspectives
may inform window length but never override the binding CIO's veto.
