Finn, of Vantage Consulting Group, introduce a methodology for constructing an equity index in which the weight assigned to each component is determined by reference to the nature of the business risks to which it is exposed. The methodology uses the technique of statistical stratification to maximize the index’s diversification across different categories of business risks.Using the populations of the S&P 500 and the S&P MidCap 400 indexes, the authors compare the performance of stratified indexes created using their methodology to both market-capitalization-weighted and equal-weighted indexes comprising the same components. They find that the stratified indexes delivered higher returns and higher Sharpe ratios than the others.TOPICS: VAR and use of alternative risk measures of trading risk, performance measurement ER -
