Abstract
This paper examines various risk-efficient solutions that enable investors to optimize their risk-return profile in comparison to the traditional market-capitalization index. Investment practitioners and other equity analysts considered cap-weighted market indices as neither efficient nor diversified; due to some notable drawbacks such as overconcentration of large-cap, price noise, massive drawdown, absence of an auto-corrective mechanism of mean reversion; and others. Therefore, the purpose of the study is to explore the diverse range of risk-efficient strategies that improve the quality of the index constitution. Using the extensive sample of the S&P BSE 500 index, the study examines the performance, consistency, and robustness of optimization-based risk-efficient solutions, including; Efficient minimum variance, Diversified risk-weighted, Maximum decorrelation, Maximum deconcentration, Efficient maximum Sharpe ratio, and Diversified Multi-Strategy for the period April 1, 2004, to March 31, 2020. The result of the study presents evidence of diversification enhancement and extensive outperformance for these risk-efficient solutions.
