## Quick DCF Reference

### WACC Formula and Components

```
WACC = Ke × (E/V) + Kd × (D/V)

Where:
  Ke  = Cost of Equity  = Rf + β × (Rm − Rf) + Size Premium
  Kd  = After-Tax Cost of Debt  = (Interest Expense / Total Debt) × (1 − Tax Rate)
  E/V = Equity Weight  = Equity Market Cap / (Equity Market Cap + Total Debt)
  D/V = Debt Weight    = Total Debt / (Equity Market Cap + Total Debt)

Typical WACC Ranges by Risk Profile:
Risk Profile         WACC Range    Examples
─────────────────────────────────────────────────────
Low risk (utility)   6–8%          Regulated utilities, large cap staples
Medium risk          8–11%         Large cap tech, established growth
High risk            11–15%        Small cap, emerging market, cyclical
Very high risk       15–20%+       Early-stage, distressed, pre-revenue
```

### Three-Scenario Names and Default Probabilities

```
Scenario    Probability    Narrative
Bull         20%           Market share gains, margin expansion, favorable macro
Base         60%           Historical trend continuation, guidance-aligned
Bear         20%           Competitive pressure, margin compression, macro headwinds

Probability-Weighted IV = (20% × Bull IV) + (60% × Base IV) + (20% × Bear IV)
```

### 5×5 Sensitivity Table Template

```
Sensitivity Table — Intrinsic Value per Share ($)
              Terminal Growth Rate
WACC     1.0%    1.5%    2.0%    2.5%    3.0%
6.0%     $xxx    $xxx    $xxx    $xxx    $xxx
7.0%     $xxx    $xxx    $xxx    $xxx    $xxx
8.0%     $xxx    $xxx    $xxx    $xxx    $xxx  ← Base Case
9.0%     $xxx    $xxx    $xxx    $xxx    $xxx
10.0%    $xxx    $xxx    $xxx    $xxx    $xxx
```

### Terminal Value Formula

```
Gordon Growth Model:  TV = FCF₁₀ × (1 + g) / (WACC − g)
Exit Multiple Method: TV = FCFₙ × (EV / FCF exit multiple)

Rule: Never set g > WACC. Flag if TV > 80% of total Enterprise Value.

## Thesis Invalidation

After delivering the analysis signal, specify what would reverse it:

**If signal is BULLISH — thesis breaks if:**
- Price closes below the MA200 / key support level identified in this analysis on above-average volume
- FCF turns negative for 2 consecutive quarters OR WACC rises >200bps unexpectedly
- Macro regime shift: Fed pivots hawkish unexpectedly, recession probability >60%

**If signal is BEARISH — thesis breaks if:**
- Price closes above key resistance / MA200 level with volume confirmation
- FCF growth accelerates >20% above model assumptions OR interest rates fall >100bps
- Fundamental improvement: surprise earnings beat >20% with guidance raise

**Re-run this analysis when:**
- [ ] Next earnings release
- [ ] Price moves ±15% from current level
- [ ] 60 days have elapsed
- [ ] Material news event (acquisition, leadership change, regulatory decision)
