Step 1: Anchor scenarios to historical macro data
Load the merged regime history and preserve its monthly frequency. Record the date range, observation count, regime mix, inflation band, median Fed Funds anchor, latest 10-year risk-free rate, latest proxy WACC, and baseline PV before changing any assumptions.
What success looks like: The model clearly identifies 257 monthly observations from 2005-01-01 to 2026-05-01 and retains the $1,460.6 baseline.
Common mistake to avoid: Do not mix monthly history with unlabelled observations from a different frequency.
Step 2: Define the macro-regime logic
Apply the supplied classification rules consistently. Bull or Easing uses sub-20 VIX readings and comparatively stable Treasury moves; Bear or Tightening uses VIX above 25 with rapidly rising rates; Base or Normal captures middle-ground conditions.
What success looks like: Every month has one regime label, and the historical mix totals 153 Base months, 43 Bear months, and 61 Bull months.
Common mistake to avoid: Do not treat the regime overlay as a replacement for the underlying time series.
Step 3: Build discount-rate assumptions by regime
Create one row for each regime and include risk-free rate, credit spread, term spread, Fed Funds, proxy WACC, and PV. The supplied values are Base: 2.84%, 1.23%, 0.65%, 1.41%, 4.08%, and $1,478.6; Bear: 4.10%, 1.01%, 0.10%, 3.94%, 5.10%, and $1,376.2; Bull: 2.20%, 1.83%, 1.57%, 0.14%, 4.02%, and $1,484.1.
What success looks like: Each proxy WACC can be traced back to a visible set of rate components.
Common mistake to avoid: Do not change the valuation cash-flow assumptions between regimes when the goal is to isolate discount-rate sensitivity.
Step 4: Run the valuation scenarios
Apply each regime’s proxy WACC to the same valuation cash-flow assumptions. Then calculate the change versus the baseline in both dollar and percentage terms: Base is +$18.0 and +1.2%, Bear is -$84.4 and -5.8%, and Bull is +$23.5 and +1.6%.
What success looks like: The scenario PV range is $1,376.2 to $1,484.1, with the Bear case clearly identified as the downside case.
Common mistake to avoid: Do not report only the percentage change when the dollar movement is available and decision-relevant.
Step 5: Compare the rate build-up
Use a grouped comparison for risk-free rate, credit spread, term spread, Fed Funds, and resulting proxy WACC. This makes it possible to distinguish a valuation change driven by policy rates from one driven by another part of the discount-rate build-up.
What success looks like: The grouped view makes the Bear proxy WACC of 5.10% and its $1,376.2 PV immediately visible.
Common mistake to avoid: Do not compare WACC values without displaying the component assumptions that produced them.
Step 6: Analyze inflation and policy-rate clustering
Plot CPI year-over-year inflation on one axis and Fed Funds on the other. Use the 1.54% to 3.34% inflation reference band, the 0.90% median Fed Funds anchor, and regime colors to show where observations cluster.
What success looks like: The chart shows the relationship between inflation, policy rates, and regime labels without hiding the reference band.
Common mistake to avoid: Do not remove the reference values when presenting the scatter or clustering view.
Step 7: Review historical rate paths
Track the historical risk-free rate and proxy WACC over time. Shade tightening and easing periods, while leaving normal-regime periods unshaded so the contrast remains readable.
What success looks like: A reader can identify rate-path changes and see where the regime overlays begin and end.
Common mistake to avoid: Do not use shading that obscures the rate lines or the dates of regime changes.
Step 8: Review the monthly regime map
Create a month-by-month map showing the frequency and timing of Bull, Base, and Bear periods. The related recent 126-observation analysis reports Bull at 71.4%, Base at 28.6%, Bear at 0.0%, and the latest observation as Bull.
What success looks like: The map shows whether the current scenario resembles a common or unusual historical environment.
Common mistake to avoid: Do not use the recent 126-observation mix as a substitute for the full 257-observation history.
Step 9: Present the valuation sensitivity
Finish with a PV tornado chart centered on the $1,460.6 baseline. Show Bull at +$23.5, Base at +$18.0, and Bear at -$84.4, then explain why the Bear case has the largest movement.
What success looks like: The audience can understand the valuation range and downside without reading the entire model.
Common mistake to avoid: Do not center the chart on a scenario value instead of the stated baseline anchor.
