New Scientific Beta Paper Highlights Sector Investment Risk
Traders Magazine Online News, September 25, 2018
In a new publication entitled “Managing Sector Risk in Factor Investing,” ERI Scientific Beta researchers focused on the implicit sector risk taken by smart factor indices and analyse the implications for their short- and long-term risk-adjusted performance.
Focusing on a comparison between standard smart factor indices and their sector-neutral counterparts, the authors highlight several key findings:
- Sector-neutrality adds value in terms of reducing tracking error and short-term underperformance with respect to the reference cap-weighted index. De facto, a large share of the underperformance attributed to factors in recent years actually relates to sector biases.
- Sector-neutrality nonetheless comes with costs in the form of higher volatility and lower factor intensity. Investors who wish to maximise the benefits of factor investing over the long term should therefore question the idea of protecting the short term through sector neutrality.
- It is precisely the objective of Scientific Beta’s Smart Beta 2.0 framework to allow investors to make such explicit choices, not just on the targeted factors but also on additional risk control options
The authors conclude that the choice of using the sector-risk-control option is a trade-off between investors’ aversion to short-term risks generated by sector risk and their willingness to harvest factor risk premia in the most efficient way, to achieve the highest risk-adjusted performance over the long run.
