Begin by shifting attention from the next quarter or year to what the business and its industry could look like five to seven years ahead. Research the underlying economics, then model low, base, and high outcomes rather than relying on one precise forecast. The purchase should offer an attractive return in the base case, meaningful optionality in the high case, and tolerable damage in the low case. Risk is defined primarily as permanent impairment of capital, not temporary mark-to-market volatility. This distinction allows an investor to buy during fearful sell-offs when price declines exceed any plausible deterioration in long-term value. The resulting decision is rational rather than brave because it rests on conservative valuation boundaries and a sufficiently long holding period.
Origin
Extracted from Masters in Business, where Steve Romick explained the long-horizon scenario process used by the FPA Crescent Fund.
Core principles
- 01Treat permanent capital impairment as the primary risk
- 02Judge investments over five to seven years
- 03Demand an attractive base case before relying on upside
- 04Use low, base, and high cases to bound uncertainty
- 05Separate temporary price volatility from business deterioration
How to run it
- 1
Set the horizon
Evaluate the investment over five to seven years rather than attempting to predict the next few months. Define why the underlying business should remain relevant across that period.
Pro tip Write the long-term thesis before looking at recent price movements.
Watch out A long horizon cannot rescue a structurally deteriorating business.
- 2
Research the underlying business
Study the company, competitors, management, industry experts, and relevant assets or liabilities. Determine the economic drivers that matter over several years.
Pro tip Use conversations and primary-source reading to challenge the published narrative.
Watch out Do not let a detailed financial model substitute for understanding the business.
- 3
Build three outcome cases
Model low, base, and high cases using defensible assumptions. Treat the cases as boundaries rather than precise forecasts.
Pro tip Make the low case severe enough to expose hidden fragility.
Watch out Optimistic assumptions across all three cases destroy the value of the exercise.
- 4
Test base-case attractiveness
Require the investment to produce an acceptable return in the base case. Regard the high case as optional upside rather than the justification for buying.
Pro tip State the expected return and valuation endpoint explicitly.
Watch out Do not buy an investment that only works in the high case.
- 5
Identify permanent impairment
Determine what could permanently destroy capital, including insolvency, disruption, dilution, regulatory damage, or irreversible loss of earning power. Distinguish these outcomes from temporary price declines.
Pro tip Translate each impairment risk into an observable thesis-break condition.
Watch out A falling price is not automatically temporary; revisit the business evidence.
- 6
Act on the price-value gap
Buy when the current price provides sufficient protection against the low case and attractive returns in the base case. Continue holding through volatility while the long-term thesis remains intact.
Pro tip Preserve some capacity to buy if the price falls further without thesis deterioration.
Watch out Do not confuse confidence in the business with certainty about the market bottom.
In the wild
As travel stopped and Marriott's share price fell sharply, Romick focused on whether people would travel and use hotels again after the pandemic. The company's asset-light model supported the long-term case even though near-term occupancy had collapsed, so the fund bought as the stock declined rather than waiting for a clear market bottom.
→ The position recovered strongly as travel normalized, supporting the long-term business thesis.
An investor studies a profitable industrial supplier after a recession cuts its share price in half. The low case assumes two weak years and lost customers, the base case assumes gradual normalization, and the high case includes market-share gains. The investor buys only after confirming that liquidity survives the low case and the base-case return remains attractive.
→ The decision is grounded in bounded business outcomes rather than a prediction of the recession's end.
Common mistakes
Predicting the exact market bottom
Waiting for certainty about when a downturn will end can prevent an investor from buying assets already priced for severe outcomes.
Using volatility as the risk definition
Price movement alone does not reveal whether the underlying capital has been permanently impaired.
Relying on the upside case
An investment that requires the optimistic scenario lacks a sufficient margin of safety.
Is it for you?
Best for
It is best for patient investors evaluating public equities, credit, or other assets through uncertain market conditions.
Not ideal for
It is not ideal for short-term traders, forced sellers, or investors unable to tolerate substantial interim drawdowns.
From the transcript
“it's very important for us to always be mindful of what the world will look like five to seven years, you know, down the road”
“We want to have a view as to what the business might look like in a low base and high case”
“what could really happen that could create a permanent impairment of capital.”
