Creating a blended benchmark involves combining multiple market indices based on your portfolio's specific asset allocation. This custom yardstick provides an accurate measure of performance for diversified global portfolios that standard single-index benchmarks cannot capture.
Why Use a Blended Benchmark?
Standard indices like the S&P 500 do not reflect global portfolios containing international equities, bonds, and emerging markets. A blended benchmark weights different indices according to your target asset allocation, offering a realistic baseline to evaluate your investment strategy and risk-adjusted returns.
Steps to Create Your Blended Benchmark
- Determine Target Allocation: Identify the exact percentage of your portfolio assigned to each asset class or region (e.g., 60% global equities, 30% bonds, 10% emerging markets).
- Select Appropriate Indices: Choose representative indices for each bucket, such as the MSCI World for developed equities and the Bloomberg Global Aggregate for bonds.
- Calculate Weighted Returns: Multiply each index's monthly return by its target weight and sum the results to find the composite benchmark return.
