PRISM™ is an index-based solution intended to provide multi-asset diversification within a simple risk-weighting framework. Constructed as an index of indices, it measures the performance of an inverse-risk-weighted basket of three component indices representing fixed income, equities, and commodities, after accounting for technical and fundamental indicators.

  • Fixed Income

    Fixed income is represented by the S&P Ultra 10-Year U.S. Treasury Note Futures Index

Methodology Highlights

Volatility Scalars

Equities:

  • 10-year yield vs. earnings yield
  • Yield curve multiplier: lagged 60-day average spread between 10-year and 3-month U.S. Treasury rate

Fixed Income:

  • 200-day index moving average

Asset Weighting Strategy

Equities, fixed income, and commodities are weighted by the inverse of their volatility.

Volatility / Risk Control Framework

Volatility target of 5.5% is achieved by allocating to the reference index versus cash.

Asset Weighting Strategy

  • 1. Calculate three trend allocation signals representing the three asset classes in the index

  • 2. Rank long-term asset class returns on 200-day excess returns

  • 3. Scale volatilities based on momentum, valuation, and yield curve multiplier

  • 4. Weight components by the inverse of their volatility

  • 5. Calculate the reference index on a 2-day lag

  • 6. Add a risk-control overlay with a 5.5% target to create the S&P PRISMTM Index
