Key Findings

1

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.

2

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.

3

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.

4

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.

5

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.

6

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.
