In this paper, we present a daily factor model that forecasts daily volatility of variance for VIX Futures Contracts.

This Model Insight explains the Barra Commodity Model (COM2), which covers a broader set of commodities, attributes risk to an expanded set of factors, and provides more accurate risk estimates along the commodity term structures.

Factor models are standards in investment management. For decades, Barra factor models have provided valuable risk forecasts and inputs for the portfolio construction process.

Precise statements of this miracle are known as Central Limit Theorems, and...
