The Quest for Neutrality in Asset Allocation
A new study questions the common market-cap weighting in asset allocation, comparing it to six risk-based strategies across nearly 30 years of global equity sector data. All risk-based methods beat the standard Capital Asset Pricing Model (CAPM) in risk-adjusted returns. The Conviction Parity approach stands out for its balanced risk, high information ratio, and low turnover. The paper’s use of entropy-based measures to assess diversification offers a fresh, quantitative perspective, though findings are limited to equities.
What it examines
This paper examines different risk-based asset allocation strategies as alternatives to traditional market-capitalization methods. It aims to find a more neutral and diversified approach by equalizing specific risk measures across assets, using empirical analysis of sector data and embedding these strategies within the Black-Litterman model.
What it concludes
The study finds that Conviction Parity offers the most balanced and stable portfolio, outperforming traditional benchmarks. This approach can help investors build more diversified and robust portfolios. The findings are useful for strategic asset allocation and suggest future research on risk-based neutrality in portfolio construction.

All risk-based strategies, especially Conviction Parity, outperform the traditional CAPM benchmark in risk-adjusted returns, offering more balanced risk, higher information ratios, lower turnover, and even idiosyncratic risk distribution.

Innovatively, the authors use entropy-based measures to quantify diversification, but note their findings are limited to equity sectors, suggesting further research is needed to generalize across other asset classes.

This paper innovatively addresses portfolio optimization by introducing a risk-based neutrality framework, systematically comparing six strategies, and embedding them as reference portfolios within the Black-Litterman model. The novel 'Conviction Parity' concept and empirical validation distinguish it, offering compelling insights for robust, diversified asset allocation beyond traditional market-cap and CAPM benchmarks.
