How do I calculate intrinsic value using the two-stage DDM?
I understand the Gordon Growth Model for constant growth, but CFA Level I also requires the two-stage dividend discount model where growth changes after a few years. I'm having trouble with the transition from high growth to stable growth. A full numerical example would be amazing.
The two-stage DDM is used when a company is expected to grow dividends at a higher rate initially and then settle into a lower sustainable rate. It combines a high-growth phase with a terminal value at the transition point.
Formula:
> V_0 = Sum of PV(dividends during high-growth phase) + PV(terminal value)
Where the terminal value at year N uses the Gordon Growth Model:
> TV_N = D_(N+1) / (r - g_stable)
Full Worked Example:
Brightwater Industries pays a current dividend (D_0) of $2.00. You expect:
- High growth rate: 15% for 3 years
- Stable growth rate: 4% thereafter
- Required return (r): 11%
Step 1: Project dividends during high growth
| Year | Dividend | Calculation |
|---|---|---|
| D_1 | $2.30 | $2.00 x 1.15 |
| D_2 | $2.645 | $2.30 x 1.15 |
| D_3 | $3.042 | $2.645 x 1.15 |
Step 2: Calculate terminal value at end of Year 3
D_4 = $3.042 x 1.04 = $3.163
TV_3 = $3.163 / (0.11 - 0.04) = $3.163 / 0.07 = $45.19
Step 3: Discount everything back to today
| Cash Flow | Year | PV Factor (11%) | PV |
|---|---|---|---|
| D_1 = $2.30 | 1 | 0.9009 | $2.072 |
| D_2 = $2.645 | 2 | 0.8116 | $2.147 |
| D_3 = $3.042 | 3 | 0.7312 | $2.224 |
| TV_3 = $45.19 | 3 | 0.7312 | $33.04 |
V_0 = $2.072 + $2.147 + $2.224 + $33.04 = $39.48
Common Mistakes:
- Using D_0 instead of D_1 in the terminal value. The Gordon model needs the next period's dividend, so at Year 3, you need D_4.
- Forgetting to discount the terminal value. TV_3 is the value at Year 3, not today. You must discount it back 3 years.
- Adding D_3 twice. D_3 is a regular dividend AND the base for the terminal value. Count the dividend payment in Year 3 AND the terminal value — but D_3 is not inside the terminal value (D_4 is).
When to use 2-stage vs. Gordon:
- Gordon (single stage): mature companies with stable, sustainable growth
- Two-stage: companies in growth phases (tech, biotech) expected to normalize
