Key Findings
No stock is immune to crisis
Every single one of the 300 stocks in our database suffered losses in at least 6 of 7 crises. Diversification reduces risk — but cannot eliminate it.
The 2008 GFC was the most destructive
With an average drawdown of -46.1%, the Global Financial Crisis inflicted the deepest average damage across all 300 stocks. No sector was spared.
Concentration risk is real
174 stocks (58.0%) lost more than 50% of their value in at least one crisis. A single outsized position can devastate a portfolio.
Defensive sectors outperform — but not always
Consumer Staples, Healthcare, and Utilities typically lose less during crises, but their resilience varies. In the 2022 rate hike cycle, traditional defensives were not the best shelters.
Recovery speed varies dramatically
The COVID-19 crash saw a full recovery in 5 months. The dot-com bust took the S&P 500 seven years to recover, and the Nasdaq 15 years. The nature of the crisis matters as much as its depth.
Historical stress testing reveals hidden fragility
Many stocks that appear stable in normal conditions show extreme vulnerability under specific crisis types. A comprehensive stress test across multiple scenarios is the only way to identify these hidden risks.
Methodology
This report analyzes 300 individual stocks across 7 major market crises spanning from 1987 to 2022.
Stock universe: Current members of the Dow Jones 30, top Nasdaq 100 constituents by market cap, S&P 500 selections, EuroStoxx 50, FTSE 100, FTSE MIB, and Nikkei 225 — covering US, European, and Asian equities.
Returns: Peak-to-trough total returns during each crisis period, expressed as decimals (e.g., -0.57 = -57% loss). For stocks that did not exist during a given crisis, the corresponding sector ETF return is used as a proxy.
Crises covered: Black Monday (1987), Bond Massacre (1994), Dot-com Bust (2000-2002), Global Financial Crisis (2008-2009), European Debt Crisis (2011), COVID-19 Crash (2020), and the 2022 Rate Hike Cycle.
Calculations: All averages are simple arithmetic means. Sector averages are equally weighted across all stocks in each sector. All computations run server-side from the BSL stock database at build time.
