Risk-based indices are different from factor-based indices, as they focus on the interaction between securities, not the characteristics within securities. Put simply, it's an alternative, systematic approach to asset allocation and risk management.
The Elston Multi-Asset Min Volatility Index (ESBGMV Index) launched in 2014 represents the minimum variance multi-asset portfolio for GBP investors.
As it takes a systematic approach, it's always interesting to see the asset-class switches that this methodology triggers via its monthly readjustments.
Comparing the index composition from 4q17 to 1q18, the biggest switches have been cutting back European High Yield Bonds and UK Equity, whilst adding to European Aggregate Bonds and Gold.
