Eliminating Coverage Gaps

Competing indices may inadvertently create a gap in coverage by excluding Canadian securities. The S&P Developed Ex-U.S. BMI eliminates that gap, covering all 24 developed market countries outside the U.S.

The Foundation for a Wide Range of Strategy Indices

S&P Global BMI indices serve as performance benchmarks, the basis for passive investment products, and as a universe for historical market analysis and backtesting investment strategies. S&P Global BMI indices also serve as the foundation for more complex strategy indices, including those targeting factors and ESG. Using a comprehensive underlying global benchmark with consistent historical data helps to avoid unintended biases when constructing more complex strategy and custom indices.
