Historical Market Replay

💡 What This Tool Does

The Historical Market Replay tool shows how the modeled retirement plan would have performed during specific historical market periods. It replays actual market returns from past decades to show real-world outcomes.

Key Questions It Answers:

• How would my plan have performed in the 1970s?
• What if I retired in 2000 (dot-com crash)?
• How did the 2008 crisis affect similar plans?
• What can I learn from past market cycles?

📋 How to Use This Tool

Before Starting

Have modeled retirement plan inputs ready:

• Retirement account balances
• Withdrawal strategy
• Asset allocation
• Retirement timeline

Step-by-Step Instructions

1. Select Historical Period: Choose decade or specific period
2. Set Starting Conditions: The portfolio at start of period
3. Run Replay: See how plan performs with actual returns
4. Review Results: Analyze outcomes and lessons learned
5. Compare Periods: See how different eras affected plans

🔍 What to Look For

Key Metrics

1. Portfolio Performance: How balance changed over period
2. Survival: Whether plan lasted through period
3. Recovery: How quickly portfolio recovered
4. Lessons: What worked and what didn't

📊 How to Interpret Results

Understanding the Output

Historical replays show real-world outcomes, not projections. They demonstrate how the plan would have fared in actual market conditions.

Next Steps

1. Test multiple historical periods
2. Learn from past market cycles
3. Apply lessons to strengthen plan
4. Combine with Monte Carlo for full picture

🎓 Learning from History

The Sequence Risk Reality

Historical replays show that retirement timing matters as much as savings rate. Poor early returns can devastate a portfolio despite good average returns.

Worst Retirement Years

1966, 2000, and 1968 were historically the worst years to retire based on subsequent market performance. Plans that survived these are well-designed.

Recovery Patterns

Historical data shows markets recover, but timing matters. Building cash reserves for early retirement years provides crucial flexibility during downturns.

❓ Frequently Asked Questions

Q1: What can history teach us about retirement?

History shows sequence of returns matters enormously. The same portfolio can succeed or fail based purely on retirement timing relative to market cycles. This is why stress testing is crucial.

Q2: What's the worst historical period to test?

Retiring in 1966 (before 1970s stagflation) is historically worst-case. If the plan survives this scenario, it is very robust. 2000 (dot-com crash) is the second-worst.

Q3: Can historical results predict my retirement?

No, but they provide valuable scenarios. Markets may behave differently, but historical testing shows how the plan handles real volatility and sequence risk.

Q4: Should the plan pass every historical scenario?

Not necessary. Passing 8-9 out of 10 scenarios is excellent. Designing for absolute worst-case means being too conservative and sacrificing growth.

Q5: How is this different from Monte Carlo?

Historical replay uses actual market returns from specific periods. Monte Carlo uses random simulations. Historical testing shows what actually happened; Monte Carlo shows statistical possibilities.
