The Live-to-Fight-Another-Day Risk Test evaluates an investment at the portfolio level rather than accepting its expected return as sufficient evidence of safety. Begin with the base case, then model meaningful deviations such as falling equity prices, interest-rate shocks, margin calls, lost revenue, or counterparty failure. For each scenario, identify ongoing cash obligations and determine which assets can be converted to cash promptly without intolerable losses. The central output is a survival judgment: whether the investor can reach the other side of the stress without forced liquidation or failure. This approach does not require predicting every extraordinary event. Instead, it creates liquidity and structural resilience against a range of adverse outcomes, allowing time for asset values, revenues, or market conditions to recover.
Origin
Extracted from Masters in Business as Julian Salisbury compared investment risk management with merely owning assets and reflected on SVB and UK pension stress.
Core principles
- 01Every investment has outcomes beyond its base case
- 02Survival matters more than precision during extreme events
- 03Liquidity buys time to recover
- 04Cash-flow obligations persist during market drawdowns
- 05Concentrated and leveraged exposures amplify tail risk
How to run it
- 1
Define the Base Case
State the expected return, cash flows, maturity, and repayment path for the asset or portfolio.
Pro tip Make assumptions explicit enough that another person can challenge them.
Watch out Do not confuse the most likely outcome with the only possible outcome.
- 2
Map Major Deviations
Model severe changes in prices, rates, revenue, funding access, and counterparty health.
Pro tip Use recent crises to expand the scenario set without assuming the next crisis will be identical.
Watch out A narrow historical range can conceal extreme but survivable events.
- 3
Calculate Stress Cash Needs
Estimate operating costs, withdrawals, margin calls, debt service, and other payments during each scenario.
Pro tip Include obligations that accelerate when markets move adversely.
Watch out Accounting solvency does not guarantee cash-flow survival.
- 4
Inventory Usable Liquidity
Identify cash and assets that can realistically be sold or pledged during stress, accounting for falling prices and market depth.
Pro tip Discount the assumed value of assets likely to become correlated during a crisis.
Watch out Do not count an illiquid asset at its normal-market valuation as immediate cash.
- 5
Run the Survival Test
Compare stress liquidity with stress obligations and determine whether the portfolio can endure until conditions normalize.
Pro tip Focus on the most binding period rather than only the final outcome.
Watch out A temporary shortfall can permanently destroy an otherwise sound position.
- 6
Build the Buffer
Diversify counterparties, extend funding duration, reduce leverage, or increase liquid reserves where the test exposes failure points.
Pro tip Prioritize fixes that protect against several scenarios at once.
Watch out Optimization for ordinary conditions can remove the buffer needed in extraordinary ones.
In the wild
A company holding hundreds of millions of uninsured dollars at one bank applies the survival test. It models the bank becoming inaccessible, recognizes that payroll and operating bills would remain due, and divides cash across institutions and diversified money-market instruments.
→ A single bank failure no longer threatens the company's immediate operations.
An investor models a period in which both equities and bonds decline while regular cash distributions continue. The investor holds a dedicated liquidity reserve and avoids relying on the sale of depressed risk assets to fund those distributions.
→ The portfolio can wait for recovery instead of realizing losses under pressure.
Common mistakes
Testing Only the Base Case
Expected coupons or long-run appreciation say little about whether an investor can survive the path to that outcome.
Treating All Assets as Liquid
Assets that appear saleable in calm markets may require steep discounts or become temporarily untradeable during stress.
Concentrating Critical Cash
Keeping operationally essential funds with one counterparty creates a preventable single point of failure.
Is it for you?
Best for
It is best for investors, companies, and committees evaluating portfolios with leverage, cash obligations, or concentrated exposures.
Not ideal for
It is not a substitute for detailed security analysis or a prediction of the exact crisis that will occur.
From the transcript
“what you have to really do for each client is help the understand what's the risk of the deviation that could occur around that base…”
“Can I live to fight another day?”
“number one, two and three is liquidity.”
