Core formula
Call value = S·N(d1) − K·e^(−rT)·N(d2), where S is the PV of post-commercialization cash flows and K is the cost to exerciseHow to interpret it
Prices pipeline assets, undeveloped reserves, or explicit expansion/abandonment options as call options via Black-Scholes, capturing unpriced optionality that a DCF would otherwise value at zero or negative.
The output should be read as a scenario or decision aid, not as a guaranteed price target. Compare it with at least one method based on different economic assumptions.
Practical workflow
- Normalize the latest public financial and operating data.
- Choose assumptions that match the company's economics and accounting structure.
- Calculate conservative, base and optimistic cases where the method permits.
- Compare the result with market pricing and an independent valuation method.
- Document the assumptions that drive the largest changes in value.
Key limitation
Volatility and underlying value are highly subjective; only use when a concrete optionable asset can be identified, never as a precise fair value.
How Stockinsky uses it
Stockinsky uses this framework only when the company type and available data support it. Professional valuations expose assumptions, sources and warnings instead of presenting false precision.
