Msci World Backtest -

Zero transaction costs, no taxes, perfect liquidity, monthly rebalancing to cap weights.

Executive Summary

7/10 (Deducted points for survivorship bias, dividend tax ambiguity, and currency overhang) msci world backtest

Yes, but only alongside a Monte Carlo simulation and a rolling-window analysis. A single line from 1987 to 2026 is a trap.

Annualized return ~23%. The MSCI World became increasingly tech-heavy (US tech weight grew from ~10% to 28%). Backtest shows this period was driven by multiple expansion, not earnings. Warning: many backtests fail to adjust for the fact that MSCI removed some tech losers post-2000 (survivorship bias). Zero transaction costs, no taxes, perfect liquidity, monthly

| Metric | Value | |--------|-------| | Total Return (cumulative) | ~1,840% | | Annualized Return (CAGR) | 8.1% | | Annualized Volatility | 15.2% | | Sharpe Ratio (risk-free = 3% avg) | 0.34 | | Maximum Drawdown | -52.7% (Oct 2007 – Feb 2009) | | Worst Year | -40.3% (2008) | | Best Year | +36.2% (1997) | | Positive years | 28 out of 39 (~72%) |

The index launched just before the 1987 Black Monday crash (-23% in one month). This is a critical reminder: even diversified global equity can crash simultaneously. Recovery took 22 months. The early 1990s recession and Gulf War saw flat returns. Annualized return ~23%

The MSCI World backtest is a powerful tool, but only if you respect its limitations. The raw numbers (8%+ annualized) are real, but they mask decade-long bear markets, currency chaos, and the constant risk of extinction-level events. The best use of this backtest is not to predict the future, but to calibrate your risk tolerance: if a -52% drawdown makes you panic, the MSCI World is too aggressive for you. If you can hold steady and rebalance, it remains one of the most robust long-term equity building blocks ever created.
