Scenario Analysis and Probability Weighting
Learning Objectives
Construct rigorous scenarios that are mutually exclusive, collectively exhaustive, and internally consistent
Assign defensible probabilities using base rates, reference classes, and structured judgment
Calculate probability-weighted expected values for XRP under uncertainty
Avoid common scenario analysis mistakes including arbitrary scenarios and overconfident probabilities
Update scenarios and probabilities as new information becomes available
Every valuation model we've built contains uncertain inputs: ODL growth, velocity, adoption rates, regulatory outcomes. Rather than picking single "best guesses," scenario analysis explicitly models multiple futures.
This isn't about predicting which scenario will occur—it's about understanding the distribution of outcomes and making decisions that account for uncertainty. A $0.50 price might be cheap if the bull case is likely and expensive if the bear case dominates. Scenario analysis reveals which.

Formula:
E[V] = Σ (Probability_i × Value_i)
For XRP:
E[Price] = P_catastrophic × Price_catastrophic
+ P_bear × Price_bear
+ P_base × Price_base
+ P_bull × Price_bull
+ P_extreme × Price_extreme
```
Calculation:
Using scenario midpoints:
E[Price] = 0.07 × $0.035
+ 0.22 × $0.07
+ 0.46 × $0.40
+ 0.20 × $1.05
+ 0.05 × $5.25
E[Price] = $0.002 + $0.015 + $0.184 + $0.210 + $0.263
E[Price] = $0.67
Current price: ~$0.50
Expected value: ~$0.67
Implied upside: 34%
What Expected Value Tells You:
E[Price] = $0.67 vs. Current = $0.50
- IF your scenarios and probabilities are correct
- AND you're risk-neutral
- THEN XRP appears undervalued
- Probabilities are subjective
- Risk aversion matters
- Time value of money
Incorporating Risk Aversion:
Risk-neutral: E[V] = $0.67
- Catastrophic scenario has -93% return
- Are you okay with 7% chance of losing 93%?
- Extreme bull requires 5-10 year hold
- Edge = (0.67 - 0.50) / 0.50 = 34%
- But variance is high
- Optimal position smaller than edge suggests
Discounting Future Value:
If scenarios describe 2030 (5 years out):
At 25% discount rate:
PV = $0.67 / (1.25)^5 = $0.67 / 3.05 = $0.22
At 15% discount rate:
PV = $0.67 / (1.15)^5 = $0.67 / 2.01 = $0.33
- At high discount rate, current price ($0.50) > PV ($0.22)
- Suggests overvalued on risk-adjusted basis
- Or discount rate is too high
- Or time horizon is different

- Material new information arrives
- Your thesis is confirmed or contradicted
- Time horizon changes
- Market conditions shift significantly
How to Update:
Original: P(Bull) = 20%
- This supports bull thesis
- Update: P(Bull) = 25%
- This supports bear/catastrophic
- Update: P(Bull) = 15%, P(Bear) = 27%

Position Sizing:
Based on expected value and risk:
- Consider larger position
- But size for downside scenarios
- Current market pricing is reasonable
- Position based on conviction in your scenarios
- Consider smaller position or none
- Unless your scenarios differ from market's
- Buy if price falls to $X (bear case value)
- Add if price falls further
- Based on scenario-implied floors
- Sell if price reaches $Y (bull case value)
- Reduce if thesis deteriorates
- Based on scenario-implied ceilings
Test Your Conclusions:
How sensitive is expected value to:
1. Probability shifts
1. Scenario values
1. Discount rate
Run sensitivity analysis on all key inputs.
✅ Scenario analysis structures thinking about uncertainty - Explicit scenarios beat implicit assumptions
✅ Expected value is mathematically correct - Given scenarios and probabilities, calculation is straightforward
✅ Probability assignment can be informed - Base rates and reference classes provide anchors
✅ Updating is necessary - Static scenarios become stale as reality unfolds
⚠️ Correct probability assignments - All probabilities are subjective judgment
⚠️ Completeness of scenarios - May miss important outcomes
⚠️ Scenario valuations - Depend on other uncertain models
⚠️ Time horizons - When scenarios materialize is unknown
📌 False precision - Expected value to decimal places implies false certainty
📌 Overconfident probabilities - Your 20% is someone else's 50%
📌 Ignoring tails - Extreme scenarios often matter most
📌 Static analysis - Scenarios must update with reality
Scenario analysis is the most honest approach to valuation under uncertainty. It doesn't pretend to predict the future—it maps the distribution of possible futures and calculates what we can expect on average. For XRP, our scenarios suggest expected value of ~$0.67 vs. current price of ~$0.50, implying modest undervaluation if our scenarios and probabilities are correct. But "if" is doing heavy lifting—different analysts with different assumptions will reach different conclusions.

Key Takeaways
Good scenarios are mutually exclusive, collectively exhaustive, internally consistent, and substantively different
: Arbitrary bear/base/bull isn't rigorous; scenarios should tell coherent stories about different futures.
Five scenarios cover XRP's range
: Catastrophic (7%), Bear (22%), Base (46%), Bull (20%), Extreme Bull (5%)—probabilities should sum to 100% and include tails.
Probability assignment uses base rates, reference classes, and inside view
: Start with historical rates for similar situations, then adjust for XRP-specific factors.
Expected value calculation is straightforward
: E[V] = Σ(P × V); for XRP, our scenarios suggest ~$0.67 expected value vs. ~$0.50 current price.
Scenarios require updating
: As new information arrives, revise probabilities systematically rather than anchoring to original estimates. ---
