Interest Rates and Stock Valuation: What CPI Means for DCF Research
A continuously refreshed research note connecting current market developments with a repeatable stock-analysis workflow. Updated November 12, 2026.
On November 10, the Bureau of Labor Statistics reported CPI up 0.4% month‑over‑month in October, with core up 0.3%. Combined with a stronger October jobs report, the print pushed Treasury yields back toward 5% on the 10‑year and hardened market expectations for a December rate increase after the Fed held policy steady on October 28. For valuation work, the important updates are mechanical: refresh the risk‑free rate you plug into WACC, reassess near‑term interest expense and lease discount rates, and stress‑test terminal growth where services inflation remains sticky. Below are the key details and a modeling checklist tied to specific release dates to avoid stale assumptions.
Macro data
CPI, jobs, and growth change the rate backdrop.
Rates
Treasury yields influence required returns and borrowing costs.
WACC
Discount-rate changes alter present values in a DCF.
DCF
Re-test growth, margins, terminal value, and sensitivity ranges.
Inflation details that matter for cash‑flow modeling
The October release showed headline CPI +0.4% m/m (after +0.6% in September) and core +0.3% m/m. Shelter rose 0.3% m/m and accounted for a large share of the increase; food rose 0.5% m/m; energy rose 0.7% m/m after a sharp September gain. For company models, (1) carry higher utilities and facility‑energy costs through Q4 run‑rates, (2) hold elevated services‑inflation assumptions in wage‑intensive lines, and (3) be careful comparing y/y rates due to the October 2025 data gap the BLS notes. The next CPI arrives Thursday, December 10—use that as the gate to refresh pricing and cost assumptions again.
Employment and wages: still supportive of demand
October’s Employment Situation showed nonfarm payrolls up and the unemployment rate little changed, with average hourly earnings advancing 0.4% m/m—the strongest monthly gain since early 2026. That mix supports top‑line demand but may extend cost pressure in labor‑heavy sectors. Translate this into models by pairing slightly firmer revenue sensitivity with sustained wage inflation in SG&A and COGS where applicable. The next jobs report is scheduled for Friday, December 4; time‑box any large changes to your demand curves until then.

Resetting discount rates with current market yields
Treasury data show the 10‑year around 4.9%–5.0% this week, and the 2‑year near 4.7% as of November 10. Replace placeholder ‘long‑run’ rates with the Treasury’s current daily par yields when you recompute WACC. For firms with refinancing in 2027–2028, update interest expense using the current curve and your spread assumptions; for lease‑heavy models, revisit the incremental borrowing rate. Also test a flatter or slightly positive curve: if 10s exceed 2s, the equity term premium you assume may need a lift, pushing fair values lower all else equal.
Fed stance and near‑term calendar
The Fed left the target range unchanged on October 28, but post‑CPI commentary from officials has kept a December hike in play. To keep research fresh, peg model updates to dates: Employment (Friday, December 4), CPI (Thursday, December 10), and PCE (Wednesday, November 25). If CPI or PCE surprise higher again, add 50–100 bps to stress‑test discount rates and trim terminal growth by 25–50 bps in rate‑sensitive sectors (utilities, REITs, capital‑intensive tech) before revisiting multiples.
A quick sensitivity checklist
- WACC: Recalculate with the current 10‑year and test +50 bps/+100 bps. - Interest expense: Roll forward maturities and apply today’s curve and spreads. - Leases: Refresh the incremental borrowing rate and right‑of‑use discount rates. - Terminal value: Pair a −25 to −50 bps cut in g with +50 bps in discount rate. - Working capital: Higher rates raise carrying costs; tighten inventory days where demand risk has risen.
Manual research versus a structured report
The app is not a substitute for judgment. Its advantage is reducing repetitive collection and organization so you can spend more time reviewing assumptions, source quality, valuation sensitivity, and risk.
| Research task | Manual workflow | With Simple AI Stock Valuation |
|---|---|---|
