DCF Scenario Planning: Bear, Base, and Bull Case Levels
Use bear, base, and bull case DCF levels to organize uncertainty around valuation, price, catalysts, and thesis review.
DCF scenario planning is most useful when the investor can see the difference between bear, base, and bull case assumptions. MyLinedChart can turn those cases into visible zones so the investor reviews uncertainty instead of pretending one value estimate is certain.
Quick Answer
Bear, base, and bull case DCF levels show the range of possible intrinsic values under different assumptions. MyLinedChart can display those values as zones with notes explaining what must happen for each case to remain valid.
Zones with notes make the DCF easier to use when price moves quickly.
Scenario Map
Each case should have its own assumption set as well as its own target price. The chart note should explain the business condition that supports the case.
The investor can then compare price to the scenario map and decide whether the market is discounting risk, pricing fair value, or getting ahead of the thesis.
| Scenario | Assumption Pattern | Chart Use |
|---|---|---|
| Bear case | Slower growth, weaker margin, higher discount rate | Downside and risk review zone |
| Base case | Most likely operating path | Main fair value range |
| Bull case | Better growth, margin expansion, stronger durability | Upside case and optimism check |
| Break case | Thesis no longer supported | Model rewrite or exit review |
| Update case | New evidence after earnings | Refresh fair value labels |
Bull, base and bear price ranges from AI, drawn on the chart
Many investors now ask an AI for a bull, base and bear target price range. The answer is only as good as the assumptions behind it, so ask for each case's growth, margin and discount rate next to its price, and check the numbers against the company's own filings.
With a direct connection, Claude or ChatGPT can read your MyLinedChart chart and propose the three ranges as zones, each with a note that states its assumptions. You approve the drawing before it lands on the chart, and the zones then sit beside price like any level you drew yourself.
MyLinedChart does not guarantee the accuracy of AI responses. Check anything important before relying on it.
- Ask for the assumptions with every price, never a bare target.
- Draw each case as a zone with its note, then compare price to the map.
- Keep the old zones when you update, so the review shows what changed.
Scenario Discipline
The danger is moving the scenario after price moves. Moving the scenario after the fact turns the model into a story. A better process updates the case only when business evidence changes.
MyLinedChart helps by keeping prior scenario notes visible for later review.

FAQ
What are bear, base, and bull case DCF levels?
Bear, base, and bull case DCF levels are valuation ranges based on conservative, likely, and optimistic assumptions for growth, margins, discount rate, and long-term durability.
Why put DCF scenarios on a chart?
The chart helps the investor see where market price sits relative to each scenario and whether the thesis requires review.
How often should DCF scenarios be updated?
Update scenarios after material evidence changes, such as earnings, guidance, filings, capital allocation changes, or thesis-breaking news.
Can AI give a bull, base and bear target price range?
Yes. An AI such as Claude or ChatGPT can propose three ranges with the assumptions behind each. Treat them as a draft: check the inputs against filings, then draw the ranges as zones on the chart to track them.
