The SGI EFS 130/30 US Index aims to track the performance of a hypothetical long/short basket of American stocks based on market cap using the Equal Factor Sensitivity methodology.
The index identifies and ranks the main sources of directional risk of the the equities in the investment universe using Principal Component Analysis (PCA).
• PCA is a statistical technique that dynamically identifies the potentially most relevant sources of risk and rank them in decreasing order of importance
• PCA provides independent sources of risk (hedging one risk away does not change the portfolio’s exposure to the other risks)
The index then chooses weights based on the allocation of the same amount of variance to each risk factor, together with taking into account usual portfolio management constraints (130/30, monthly rebalancing…)
