Company Valuation

Triangulates intrinsic value via three methods, then blends them to an implied share price:

1. DCF — 5-year FCFF projection, discount at WACC, terminal value.
2. Relative — apply peer median P/E, EV/Revenue, EV/EBITDA.
3. SOTP — when 2+ distinct reporting segments exist, value each at pure-play peer multiples.

Always present a WACC × terminal-growth sensitivity table and Bull/Base/Bear scenarios.

Step 1: Detection Flow

Detect data source and runtime deps. The skill supports 3 method paths — pick the richest one available.

Environment status:

!`python3 -c "import yfinance, numpy, pandas; print('YFIN_OK')" 2>/dev/null || echo "YFIN_MISSING"`

!`(command -v funda && funda --version) 2>/dev/null || echo "FUNDA_CLI_MISSING"`

!`python3 -c "import yfinance as yf; t=yf.Ticker('^TNX'); p=t.fast_info.last_price; print(f'RF_10Y={p/100:.4f}')" 2>/dev/null || echo "RF_FETCH_FAIL"`

Decision tree:

Condition	Method path
YFIN_OK	Path A (primary): yfinance for financials + peer multiples
YFIN_MISSING but FUNDA_CLI_MISSING is not set	Path B: delegate to finance-data-providers:funda-data skill for fundamentals
Both missing	Path C: pip-install yfinance, then Path A. python3 -m pip install -q yfinance numpy pandas
RF_FETCH_FAIL	Use default rf = 0.045 and note stale risk-free rate in output

If RF_10Y= printed, use that value as rf in Step 4d instead of the hardcoded 4.5%.

---

Step 2: Choose Methods & Set Defaults

Method applicability

Company type	DCF	Relative	SOTP	Fallback
Mature cash-flow (CPG, telecom, utilities)	✅ primary	✅	❌	—
High-growth SaaS / software	✅ with care	✅ primary	❌	Use EV/Revenue + Rule of 40
Multi-segment conglomerate	✅	✅	✅ primary	See references/sotp.md
Banks / insurance	❌	✅ (P/B, P/TBV)	❌	DDM or excess return; note in output
Pre-revenue	❌	EV/Revenue only	❌	Flag low confidence
REITs	❌	✅ (P/FFO, P/AFFO)	❌	NAV-based
Cyclicals (energy, semis, industrials)	✅ on mid-cycle	✅	sometimes	Normalize through-cycle

Defaults table

Every parameter below MUST have a value before moving to Step 3. Use these unless the user overrides.

Parameter	Default	Rationale
Projection horizon	5 years	Standard explicit forecast window
Terminal growth g	2.5%	~ long-run US GDP
Risk-free rate rf	Live 10Y UST from Step 1, else 4.5%	Current cost of capital anchor
Equity risk premium erp	5.5%	Damodaran mid-range
Beta	info['beta'] from yfinance	Market-observed levered beta
Cost of debt kd	interest_expense / total_debt, else 5.5%	Effective rate; fallback to IG spread
Tax rate	3-yr median effective rate, floored 15%, capped 30%	Strips out one-offs
Margin assumptions	3-yr median of each ratio	Smooths cyclical noise
SBC treatment	Cash for software/SaaS; non-cash for industrials/CPG	Industry convention
Peer count	4-6	Balances signal vs noise
Peer multiple	Median (not mean)	Robust to outliers
Method weights (no SOTP)	DCF 50% / Relative 50%	Equal triangulation
Method weights (with SOTP)	DCF 40% / Relative 30% / SOTP 30%	SOTP gets weight when applicable
Sensitivity grid	WACC ±1% in 0.5% steps × g from 1.5-3.5% in 0.5%	5×5 matrix

See references/wacc_erp_rates.md for current risk-free rates, ERP tables, and sector WACC benchmarks.

Step 3: Pull Data

import yfinance as yf
import numpy as np
import pandas as pd

TICKER = "AAPL"  # replace
t = yf.Ticker(TICKER)

info       = t.info
income_a   = t.income_stmt
cashflow_a = t.cashflow
balance_a  = t.balance_sheet
income_q   = t.quarterly_income_stmt
cashflow_q = t.quarterly_cashflow

earnings_est = t.earnings_estimate
revenue_est  = t.revenue_estimate

price       = info.get("currentPrice") or info.get("regularMarketPrice")
market_cap  = info.get("marketCap")
shares_out  = info.get("sharesOutstanding")
total_debt  = info.get("totalDebt") or 0
cash        = info.get("totalCash") or 0
beta        = info.get("beta") or 1.0
sector      = info.get("sector")
industry    = info.get("industry")

Key financial statement rows (yfinance labels):

Need	Row
Revenue	Total Revenue
EBIT	Operating Income
Net income	Net Income
D&A	Depreciation And Amortization (in cashflow)
CapEx	Capital Expenditure (negative)
ΔNWC	Change In Working Capital (cashflow)
SBC	Stock Based Compensation (cashflow)

Step 4: DCF Build

Full methodology + industry-specific tweaks in references/dcf.md. Quick skeleton:

# 4a. Revenue growth path — fade from Y1 (consensus or hist CAGR) to terminal g
hist_cagr = (rev[-1] / rev[0]) ** (1 / (len(rev)-1)) - 1
y1 = float(revenue_est.loc["+1y", "growth"]) if "+1y" in revenue_est.index else hist_cagr
g_terminal = 0.025
growth_path = np.linspace(y1, g_terminal + 0.01, 5)

# 4b. Margins — 3y median
ebit_margin = float((income_a.loc["Operating Income"] / income_a.loc["Total Revenue"]).iloc[:3].median())
da_pct      = float((cashflow_a.loc["Depreciation And Amortization"] / income_a.loc["Total Revenue"]).iloc[:3].median())
capex_pct   = float((cashflow_a.loc["Capital Expenditure"].abs() / income_a.loc["Total Revenue"]).iloc[:3].median())
nwc_pct     = float((cashflow_a.loc["Change In Working Capital"].abs() / income_a.loc["Total Revenue"]).iloc[:3].median())
tax_rate    = max(0.15, min(0.30, 0.21))  # use effective if available

# 4c. FCFF per year
rev_t = [float(income_a.loc["Total Revenue"].iloc[0])]
fcff  = []
for g in growth_path:
    rev_t.append(rev_t[-1] * (1 + g))
    ebit = rev_t[-1] * ebit_margin
    nopat = ebit * (1 - tax_rate)
    fcff.append(nopat + rev_t[-1]*da_pct - rev_t[-1]*capex_pct - rev_t[-1]*nwc_pct)

# 4d. WACC
rf, erp, kd = 0.045, 0.055, 0.055  # override rf with live value from Step 1
ke = rf + beta * erp
e_v = market_cap / (market_cap + total_debt)
d_v = 1 - e_v
wacc = e_v*ke + d_v*kd*(1 - tax_rate)

# 4e. Terminal value — compute both, use midpoint
tv_gordon = fcff[-1] * (1 + g_terminal) / (wacc - g_terminal)
tv_exit   = (rev_t[-1] * ebit_margin + rev_t[-1] * da_pct) * 15  # peer median EV/EBITDA
tv_base   = 0.5 * (tv_gordon + tv_exit)

# 4f. Bridge to equity
pv_fcff = sum(f / (1+wacc)**(i+1) for i, f in enumerate(fcff))
pv_tv   = tv_base / (1+wacc)**5
ev      = pv_fcff + pv_tv
equity  = ev + cash - total_debt
implied_price_dcf = equity / shares_out

Gates: (a) if wacc <= g_terminal → stop, g too aggressive; (b) if pv_tv / ev > 0.85 or < 0.45 → flag and show both TV methods; (c) if wacc is outside the sector sanity band in references/wacc_erp_rates.md → note.

---

Step 5: Relative Valuation

Select 4-6 peers. Peer map and adjustment rules in references/relative_valuation.md.

PEERS = ["MSFT", "ORCL", "CRM", "NOW", "SAP", "WDAY"]  # pick by industry
multiples = {}
for p in PEERS:
    pi = yf.Ticker(p).info
    multiples[p] = {
        "pe_fwd": pi.get("forwardPE"),
        "ev_rev": pi.get("enterpriseToRevenue"),
        "ev_ebitda": pi.get("enterpriseToEbitda"),
        "ps": pi.get("priceToSalesTrailing12Months"),
    }
med_pe     = np.nanmedian([v["pe_fwd"] for v in multiples.values()])
med_ev_rev = np.nanmedian([v["ev_rev"] for v in multiples.values()])
med_ev_eb  = np.nanmedian([v["ev_ebitda"] for v in multiples.values()])

eps_ttm    = float(income_q.loc["Diluted EPS"].iloc[:4].sum())
rev_ttm    = float(income_q.loc["Total Revenue"].iloc[:4].sum())
ebitda_ttm = float(income_q.loc["EBIT"].iloc[:4].sum()) + float(cashflow_q.loc["Depreciation And Amortization"].iloc[:4].sum())
net_debt   = total_debt - cash

implied_pe       = med_pe * eps_ttm
implied_ev_rev   = (med_ev_rev * rev_ttm - net_debt) / shares_out
implied_ev_ebit  = (med_ev_eb  * ebitda_ttm - net_debt) / shares_out
implied_price_rel = np.nanmedian([implied_pe, implied_ev_rev, implied_ev_ebit])

Adjust peer median ±10-30% if target's growth or margin profile diverges materially. Always state the adjustment and reason. Rule of 40 anchor for SaaS in references/relative_valuation.md.

---

Step 6: SOTP (multi-segment only)

Skip unless the 10-K reports 2+ operating segments with distinct economics. yfinance does NOT expose segment data — user must supply or parse from filings. Full methodology in references/sotp.md:

• Identify segments + pure-play peer for each
• Apply peer median EV/EBITDA (or EV/Rev for growth segments)
• Subtract unallocated corporate costs (cap 2-5% of revenue if unknown)
• Subtract net debt, minority interest; divide by shares

SOTP discount = (SOTP price − market price) / SOTP price. Flag if >20% (conglomerate discount).

---

Step 7: Triangulate, Sensitivity, Scenarios

# Blended implied price
if sotp_price is None:
    blended = 0.5*implied_price_dcf + 0.5*implied_price_rel
else:
    blended = 0.4*implied_price_dcf + 0.3*implied_price_rel + 0.3*sotp_price

# 5x5 sensitivity grid
wacc_grid = [wacc + dx for dx in (-0.01, -0.005, 0, 0.005, 0.01)]
g_grid    = [0.015, 0.020, 0.025, 0.030, 0.035]
sens = {}
for w in wacc_grid:
    for g in g_grid:
        tv = fcff[-1]*(1+g)/(w-g)
        pv = sum(f/(1+w)**(i+1) for i,f in enumerate(fcff)) + tv/(1+w)**5
        sens[(w,g)] = (pv + cash - total_debt) / shares_out

Also produce Bull / Base / Bear: shift revenue growth ±300bps, EBIT margin ±200bps, WACC ∓100bps, terminal g 3.0% / 2.5% / 1.5%.

---

Step 8: Respond to the User

Output in this order:

1. Headline verdict — one sentence: blended fair value, vs. current, % upside/downside, most bullish/bearish method. Example: "AAPL fair value ≈ $215 (blended), vs. current $198 → ~9% upside; DCF is most bullish at $228."
2. Snapshot — sector, industry, market cap, current price, 3M / 12M price change, LTM revenue growth.
3. Three-method summary — 3-column table: method | implied price | weight | brief rationale.
4. DCF build — assumptions table (growth path, margins, WACC components, terminal method) + 5-yr FCFF projection table + EV-to-equity bridge.
5. Peer comparison — table of peers with P/E fwd, EV/Rev, EV/EBITDA, gross margin, rev growth; bottom row = median; flag target's premium/discount.
6. SOTP (if applicable) — segment table + adjustments + equity value.
7. Sensitivity matrix — WACC × g grid (5×5), base case highlighted.
8. Scenarios — Bull / Base / Bear table with levers + implied price.
9. Key risks — 3-5 bullets: which assumption moves the answer most; what could break the thesis.

Error handling

Missing / edge case	Action
yfinance returns None for beta	Use sector-default beta from references/wacc_erp_rates.md
Negative LTM EBITDA	Skip EV/EBITDA multiple; rely on EV/Revenue + DCF
Negative LTM EPS	Skip P/E multiple; use forward P/E if positive, else skip
Growth > WACC in Gordon	Cap g = wacc − 0.5% and flag
Fewer than 3 years history	Use what's available; flag data confidence as "low"
Peer data fetch fails	Drop that peer from median; note in output
No segment data for SOTP	Skip Section 6; proceed with DCF + Relative only

Caveats to include

• TTM data lags real-time; peer multiples reflect market sentiment (can overshoot)
• DCF is garbage-in/garbage-out; sensitivity matters more than a point estimate
• yfinance data is unofficial; cross-check any decision with primary filings
• Not financial advice

Company Valuation

Estimate the intrinsic value of a public company via DCF, relative (peer multiple), and sum-of-parts (SOTP) methods, and blend into a triangulated implied share price with sensitivity tables.

What it does

• Pulls 5 years of financials + analyst estimates via yfinance
• Builds a 5-year DCF with explicit revenue / margin / WACC / terminal-value assumptions
• Applies peer median P/E, EV/Revenue, EV/EBITDA multiples across 4-6 peers
• Runs SOTP when the company has 2+ distinct reporting segments
• Presents a blended implied price with method weights, WACC × g sensitivity matrix, and Bull/Base/Bear scenarios
• Handles banks/REITs/pre-revenue/cyclical edge cases with appropriate fallbacks

Triggers

what is AAPL worth, valuation of NVDA, fair value of TSLA, DCF for MSFT, build a DCF, intrinsic value, implied share price, is X overvalued/undervalued, relative valuation, EV/EBITDA target, SOTP, sum of the parts, price target from fundamentals, value this company

Prerequisites

• Python 3.8+
• yfinance, numpy, pandas (auto-installed if missing)

Optional: finance-data-providers:funda-data skill as a fallback data source.

Platform
