Msci World Backtest File

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.

Backtesting the MSCI World Index is a cornerstone exercise for any global equity investor. It promises a window into how a diversified portfolio of developed-market stocks would have performed over decades. After conducting an extensive backtest using multiple data sources (Bloomberg, Kenneth French data library, and direct MSCI data), the results are both enlightening and treacherous. The headline is clear:

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). The index launched just before the 1987 Black

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.

Yes, but only alongside a Monte Carlo simulation and a rolling-window analysis. A single line from 1987 to 2026 is a trap. The early 1990s recession and Gulf War saw flat returns
