COMPANY ANALYSIS: FORECASTING
5 important questions on COMPANY ANALYSIS: FORECASTING
Key forecast objects include the following (4): These explain what kind of item you are trying to forecast, should I break it down or estimate it directly?
Forecast using business drivers (e.g., stores × sales per store). Most accurate and explanatory.
2. Financial statements without clear drivers
Forecast directly using last year’s number or management guidance. Avoids unnecessary complexity.
3. Summary measures (EPS, EBITDA, FCF)
Used when detail doesn’t add value; faster to forecast but less transparent.
4. Ad hoc items
One-off future events not yet in the financials (e.g., lawsuit gains/losses, regulatory costs). Added manually.
These explain which method you use to predict the number — regardless of what the item is, what technique do I use to forecast it?
- Historical results — works for stable companies
- Base rate convergence — assume company moves toward industry average
- Management guidance — use what managers predict
- Analyst discretion — use your own models when everything else fails
What is the forecast horizon, and how do investor time horizon, industry cyclicality, and company-specific factors determine its length?
- Investor or portfolio manager time horizon
- Industry cyclicality, where cyclical industries require a horizon long enough to include the midpoint of a business cycle
- Company-specific factors, such as operational changes that need enough time for their effects to become measurable

What is the purpose of combining Top-Down and Bottom-Up Revenue Forecasts?
If a company’s forecast sales from bottom-up measures (such as capacity growth or segment revenues) are significantly different from what would be expected based on top-down economic growth or industry sales, the analyst should recheck the model’s assumptions to determine whether the forecast is reasonable.
