Stress testing is not about predicting the future. It is about understanding what you own. By running your specific portfolio through historical market scenarios, you can see — in concrete dollar terms — how your holdings would have behaved during the worst market environments of the past 50 years.
Historical Market Crash Scenarios
2008 Financial Crisis
–56.8% (S&P 500)Oct 2007 – Mar 2009
The worst financial crisis since the Great Depression. Triggered by the collapse of the housing market and mortgage-backed securities. A diversified 60/40 portfolio lost approximately 30–35%.
2000–2002 Dot-Com Crash
–49.1% (S&P 500)Mar 2000 – Oct 2002
The collapse of the technology bubble. Particularly damaging for investors with heavy technology sector concentration — a common issue for workers at tech-adjacent energy companies.
2020 COVID Crash
–33.9% (S&P 500)Feb 2020 – Mar 2020
The fastest 30%+ decline in market history — just 22 trading days. Recovered quickly, but investors who sold during the panic locked in permanent losses.
1973–1974 Stagflation
–48.2% (S&P 500)1973–1974
A combination of high inflation and market decline — particularly relevant today as a scenario for retirees who depend on fixed income.
What Stress Testing Reveals
The most common reaction when investors see their stress test results is surprise. A portfolio that "feels" balanced — perhaps labeled "moderate" by a brokerage — may have lost 35–40% in 2008. For a $600,000 portfolio, that is a $210,000–$240,000 loss. For a retiree withdrawing $30,000 per year, that loss could take 7–10 years to recover from — if markets cooperate.
Stress testing also reveals concentration risk. A portfolio with significant energy sector exposure — common for Southeast Texas workers who have accumulated employer stock — may have performed very differently from the broad market in specific scenarios.
