Every generation thinks “this time is different.” It never is.
Today’s lesson is a tour through the six great equity crashes of the last century. What happened, how long markets took to recover, and what each one teaches someone investing today. If you’ll invest for 20+ years, you’ll live through at least one of these. Know what you’re up against.
Terminology
- Correction: −10% to −20% from peak. Common, frequent (every 1-2 years in equity markets).
- Bear market: −20% or more from peak. Rarer (every 5-8 years). Often triggered by recession or crisis.
- Crash: rapid decline of 20%+ in days or weeks. Especially sharp bear markets.
The line between them is fuzzy. What matters is magnitude and duration.
1929-1932: the Great Depression
Setup. 1920s “Roaring Twenties” bull market. US stocks traded at extreme valuations. Margin-financed speculation rampant.
Crash. October 28-29, 1929: Dow Jones fell 25% in two days. Kept falling.
Bottom. July 1932. Dow down 89% from 1929 peak. S&P 500 equivalent down ~85%.
Recovery. S&P 500 didn’t recover 1929 peak in nominal terms until 1954. Real terms: similar.
Lessons: leverage (margin trading) destroys wealth fast. Valuation matters for long-term returns. A 25-year recovery window means you need to be younger than 40 at the start, or you don’t see recovery.
1973-1974: the oil shock and stagflation
Setup. Nixon unpegged dollar from gold (1971). OPEC oil embargo 1973. Inflation rising. Vietnam War costs.
Decline. S&P 500 down about 48% from January 1973 to October 1974.
Recovery. S&P 500 reached new highs in August 1980. About 7.5 years peak-to-peak. Real-terms recovery (adjusted for the severe inflation of the 1970s): 12+ years.
Italian specific: “Anni di piombo” (Years of Lead) political crisis combined with inflation. Italian real returns for the decade: very poor.
Lessons: stagflation — rising inflation + stagnant growth — is the worst environment for both stocks and bonds. Inflation-linked assets or real estate outperformed.
1987: Black Monday
Setup. Market ran hot through 1987. Rising rates. Computer-driven “portfolio insurance” strategies encouraged selling on any decline.
Crash. October 19, 1987: Dow fell 22.6% in a single day. Largest one-day percentage decline in US history.
Recovery. Within 2 years, markets were back at pre-crash levels. Relatively fast.
Lessons: single-day crashes can be violent but are often recovered from if underlying economy is healthy. 1987 wasn’t accompanied by a recession; the economy kept growing.
2000-2002: the dot-com bust
Setup. Late 1990s internet mania. P/E ratios on tech stocks 100+. “This time is different” narratives.
Decline. S&P 500 down ~49% from March 2000 to October 2002. Nasdaq down 78% from peak to trough.
Recovery. S&P 500 reached 2000 peak in 2007 — just in time for the next crash.
Italian specific: FTSE MIB more moderate decline (less tech-heavy), but still significant.
Lessons: sector concentration risk. Investors concentrated in tech lost decades of their financial future. Diversified portfolios fell less.
2007-2009: Global Financial Crisis
Setup. US housing bubble inflated by subprime mortgages. Complex derivatives (CDOs) spread risk globally. Italian banks exposed via Lehman and Parmalat-style issues.
Decline. S&P 500 down ~57% peak to March 2009 trough. Global markets similar. FTSE MIB down about 70% at trough.
Recovery. S&P 500 recovered nominal 2007 peak in early 2013. About 5.5 years.
Italian specific: FTSE MIB never recovered 2007 levels. To this day, the Italian benchmark is well below its 2007 peak. Lost two decades.
Lessons: financial crises are worse than ordinary bear markets. They take longer. They destroy specific companies permanently. They prompt regulatory change that changes the rules.
2020: COVID crash
Setup. Global pandemic declared March 2020. Lockdowns. Uncertainty about economic damage.
Crash. S&P 500 down 34% in 5 weeks (Feb 19 - Mar 23, 2020). Fastest 30%+ decline in history.
Recovery. By August 2020 (5 months later), S&P 500 was back at pre-crash levels. Massive monetary and fiscal response.
Italian specific: FTSE MIB similar crash (40% trough), recovered by 2021.
Lessons: policy response matters enormously. Fed + ECB + treasuries acted fast and aggressively. Market recognized this and recovered. Without policy support, this would have been a multi-year bear market.
2022: the rate shock
Setup. Post-COVID inflation surged (Ukraine war, energy shock, supply chains). Fed and ECB raised rates fastest in decades.
Decline. S&P 500 down 25% peak to trough. Bonds down too (unusual — typically bonds rise when stocks fall). 60/40 portfolio worst year in 50 years.
Recovery. Stocks recovered 2021 peak by early 2024. Bonds still recovering at much slower pace.
Italian specific: BTP yields doubled; BTP holders saw 15-25% capital losses on longer-dated bonds. Stocks similar to global peers.
Lessons: correlation can spike during rate shocks. Bonds aren’t always defensive. Diversification across asset classes doesn’t eliminate bad years.
Common patterns across crashes
Looking at all six, some consistent themes:
1. Pre-crash indicators often visible but ignored
Before each crash, warnings existed:
- 1929: extreme P/E, rampant margin.
- 2000: P/E over 50 for tech sector.
- 2008: housing prices disconnected from incomes.
- 2020: valuations elevated, but pandemic was exogenous.
- 2022: inflation signals clearly rising by late 2021.
Smart observers noted these. Most investors didn’t act. It’s easy to recognize bubbles in retrospect, hard to time in real-time.
2. Recovery is non-linear
Stocks don’t fall linearly and recover linearly. There are false rallies (“bear market rallies”) that pull in hopeful investors before continuing to fall. Bottoming is usually a violent, chaotic process.
Trying to time the bottom rarely works. Trying to stay invested usually does.
3. Panic is the worst strategy
Data from Vanguard, Fidelity, and others consistently shows: retail investors who sell during crashes lock in losses and miss the subsequent recovery. Those who hold (or better, keep buying) do best.
The emotional difficulty of holding through −40% is enormous. Most people underestimate how hard this is until they live it.
4. Diversification helps but isn’t magic
In 2008, global stocks all fell together. In 2022, stocks AND bonds fell together. Classical “diversified portfolios” can still have brutal years.
Still, a 60/40 portfolio fell 28% in 2008 vs S&P 500’s 57%. Less bad is still less bad. Bonds typically cushion somewhat.
5. Italian markets often fare worse
FTSE MIB consistently has larger peak-to-trough drawdowns than global indices, and recovers slower. Home-bias-heavy Italians suffered disproportionately in 2008 and are still waiting for FTSE MIB to recover 2007 highs.
Global diversification is the defense.
The recovery timeline
Summary of peak-to-peak recovery times (nominal):
| Crash | Peak-trough decline | Recovery to peak |
|---|---|---|
| 1929 | −85% | 25 years |
| 1973 | −48% | 7.5 years |
| 1987 | −34% | 2 years |
| 2000 | −49% | 7 years |
| 2008 | −57% | 5.5 years |
| 2020 | −34% | 5 months |
| 2022 | −25% | 2 years |
Average recovery time for a major bear market (excluding the extreme 1929 case and the anomalous 2020): ~5-7 years.
Rule of thumb for planning: if you need money within 5 years, don’t hold stocks. The risk of still-being-down when you need to sell is too high.
The “this time is different” problem
Every generation faces a new crisis with new features:
- 1970s: stagflation was new.
- 1987: computer trading was new.
- 2000: internet was new.
- 2008: securitized mortgages were new.
- 2020: pandemic was new.
- 2022: rate shock after 14 years of zero rates was new.
Each time, some observers argued “it’s different, rules changed.” Some details did differ. But the basic dynamic — too much optimism, followed by too much pessimism, followed by recovery — repeated.
Next crisis will also feel different. Won’t be.
What to do with this lesson
Three things:
- Accept that bear markets are part of investing. If you hold equities 20+ years, you’ll experience at least one 40% drawdown. Plan for it.
- Size your equity allocation by time horizon. Money needed in less than 5 years: not in stocks. 5-10 years: partial. 10+ years: most.
- When the next crash happens, don’t sell. Not a recommendation — a commitment you make now, in advance, when your brain is calm.
