Votre stratégie survivrait-elle au prochain krach ?

Finance-focused summary (portfolio “anti-crash” strategy)

The video argues that even if markets look euphoric and valuations/concentration resemble the 2000 tech bubble, investors should not try to time the exact start/end of crashes. Instead, they should build a “crack-resistant” (anti-crash) portfolio designed to survive:

• A sharp drawdown
• More importantly, a long unfavorable sequence (years where equities stagnate or underperform)

Instruments / tickers / sectors mentioned

• Equity ETFs / equity index ETFs (generic, repeatedly referenced)
• MSCI World (MS World) ETF (example)
• S&P 500 (SNP 500) ETF (example)
• MSCI ACWI (CWI) ETF (example)
• MSCI World IMI (“CWI imi”) (example)
• Gold (used as diversification example)
• Emerging markets (mentioned as an equity asset class example in portfolio construction)
• PEA / World ETF / core equity ETF (context for how many French investors hold broad equity ETFs)
• TF (appears to mean “equity allocation / equity ETF share” or a similar portfolio equity proportion)

Note: No specific ETF tickers like SPY/QQQ/GLD were provided in the subtitles.

Key performance / risk numbers & scenario metrics

1) “2000s crash” stress test (historical analogy)

Three-year sequence (early “crack” simulation):

• Year 1: -1.9%
• Year 2: -7%
• Year 3: -34.6%

Example starting capital outcomes if 100% equity ETFs:

• €75,000 → approx -€30,000
• €150,000 → approx -€60,000
• €250,000 → more than -€100,000

After adding 2 recovery years, the model still shows:

• After 5 years: portfolio still around -34.5%
• For €250,000, this is another loss of > €86,000

---

2) DCA (savings) offset limits

Example saving rate: €500/month = €6,000/year

Weight vs. existing capital:

• If €150,000 is already invested: €6,000/year ≈ 4% of capital
• The same €6,000/year relative to €150,000 equals ~25 years of DCA

Implication vs. the simulated equity loss:

• The earlier simulated equity loss (~-€60,000) equals >10 years of that €500/month DCA stream.

Core conclusion:

• As assets grow, DCA becomes a smaller percentage of the invested base, so crash losses are harder to “work off.”

3) “Unfavorable sequence” risk (relative underperformance)

Example description: difficulty lasting “almost a decade” after equity stress.

Annualized performance figures given:

• S&P 500: -7.66% annualized
• Gold: +9.86% (~+10%)

Point: diversification matters because you’re trying to change which asset class is doing the “right job” when the equity engine is weak for years.

---

4) Allocation exposure thresholds (rule-of-thumb benchmarks)

Equity ETF exposure (“TF in equities”):

• >80%: very exposed
• 60–80%: exposed
• <60%: more controlled

Horizon benchmark:

• <15 years: high exposure (less time to absorb a sequence)
• 15–25 years: intermediate
• >25 years: lower exposure

Methodology / step-by-step framework to build an anti-crash portfolio

1. Reject market-timing

   • No reliable, reproducible method to predict when a crash starts or ends.
   • Risks:
     • Exiting late can miss the rebound
     • Waiting for confirmation can mean you act after the regime has changed

2. Measure current “impact risk”

   • Estimate:
     • Total invested amount
     • Portion in equity ETFs
   • Translate stress scenario % drawdowns into euro losses
   • Assess whether ongoing DCA can plausibly offset losses (often it cannot once capital is large)

3. Identify the “hidden risk”: dependence on the equity engine

   • Even with broad exposure (“thousands of companies” via MSCI World / S&P 500 / ACWI), many equity ETFs share the same systemic driver: the stock market.
   • The most damaging scenario is not only the maximum drawdown, but a long adverse sequence with years of weak equity performance

4. Reduce dependence via multi-asset, multi-driver construction

   • Keep equity ETFs as a potential offensive engine, but surround them with other engines (e.g., gold) that:
     • Have long-term performance potential
     • Show lower decorrelation during equity stress
     • Improve stability (reduce volatility/drawdowns)

5. Personalize the needed protection

   • Use the formula: capital × horizon × distance to target
   • Interpretations:
     • Capital: how large a crash would be in euros
     • Horizon: time available to recover before needing the money
     • Distance to target: proximity to the funding goal in capital terms (e.g., €100k vs €300k toward €400k)

6. Translate into actionable allocation guidelines

   • Adjust equity ETF share to reduce dependence:
     • If “low-exposure”: aim ≤ ~70% equity
     • If “high-exposure”: aim ~50% equity (example target)
   • Portfolio rules:
     • At least 4 major asset classes (not just 4 ETF “lines”)
     • Ensure real diversification: don’t use multiple equity ETFs that all behave the same way in drawdowns
     • Include “stable” holdings sized so 20–25% can help reduce panic during drawdowns (as stated)
   • Objective: survivability and strategy maintenance—not maximum return under perfect conditions

7. Choose “resilience” over “continuity”

   • Continuity bet: assume the favorable post-2012–2023 regime continues and drawdowns are temporary
   • Resilience bet (preferred): assume multiple scenarios, including long equity weak periods; build to work across regimes

Explicit recommendations / cautions

• Do not build a plan that only works if markets keep rising.
• Avoid relying on predicting the crash (e.g., “first signs” or timing exits/entries).
• Prioritize protection against long adverse sequences—not only the maximum drawdown.
• Limit equity ETF dependence based on:
  • horizon
  • capital size vs savings capacity
  • goal proximity
• Equity exposure guidelines mentioned:
  • Aim ~50% equity in highly exposed cases
  • Cap around ~70% equity in less exposed cases
• Minimum diversification structure:
  • at least 4 asset classes
  • include stable sleeve (~20–25%) if psychologically sensitive
• Disclosure-style content:
  • The subtitles do not include a clear “not financial advice” disclaimer explicitly.
