Global Market Index Forecast Indicates Lower Returns
A recent update to the long-term performance forecast for the Global Market Index (GMI) reveals a downward trend once again.
US Stocks Lag Behind Historical Performance
This marks the second consecutive month of declining expected returns for the GMI, which serves as an unmanaged benchmark that includes all major asset classes, excluding cash, based on various ETF proxies.
The latest estimate for the GMI has dropped to an annualized performance of 6.8%, down from 7.0% the previous month, based on an average from three different models.
When looking at recent historical data, US equities are notably underperforming, falling significantly short of their historical averages as well as the returns of other asset classes included in the GMI.
Implications for Future Returns
The average forecast for US equities is considerably lower than their performance over the past decade. This trend suggests that US stocks may provide lower returns in the coming years compared to the gains seen over the last ten years, raising concerns among investors.
Positive Outlook for Other Asset Classes
In contrast, projections for other major asset classes indicate expectations that surpass their performance over the past ten years. This trend reinforces the idea that a globally diversified portfolio is becoming increasingly attractive.
The GMI acts as a theoretical benchmark for what is considered the "optimal" portfolio for the average long-term investor. Therefore, the GMI serves as a crucial starting point for customizing asset allocation, helping investors align their portfolios with personal goals, expectations, and risk tolerance.
Understanding the Reliability of Predictions
It is important to recognize that many of the forecasts discussed may not be entirely accurate. However, projections from the GMI are generally viewed as more reliable compared to those for specific asset components. This is due to the greater volatility and tracking discrepancies associated with forecasts for individual markets, such as US stocks and commodities.
Historical Perspective on GMI Performance
To provide context, analyzing GMI’s historical total returns over time can offer valuable insights into its trajectory. Current data shows that GMI’s total return over the last decade is 7.1%, which positions it moderately compared to its historical performance.
How the GMI Forecasts are Created
The following summarizes the methodologies used to generate the GMI estimates:
BB: The Building Block model utilizes historical returns to forecast future performance. It calculates a risk premium for each asset class starting from January 1998, arriving at an annualized return and adding a risk-free rate based on 10-year Treasury Inflation Protected Securities (TIPS).
EQ: The Equilibrium model estimates expected returns using risk metrics instead of direct return predictions. This model employs a comprehensive three-input approach: evaluating expected market risk, calculating expected volatility, and determining asset correlation within the GMI.
ADJ: Similar to the EQ model, this methodology adjusts forecasts based on short-term momentum and longer-term mean reversion factors, utilizing price comparisons to moving averages.
Avg: This term represents a simple average of the three previously mentioned forecast models.
10yr Ret: This column indicates the actual trailing returns of asset classes over a ten-year period leading up to the current target month.
Spread: This is calculated as the average model forecast minus the trailing ten-year return, providing insight into performance expectations.
