RT Journal Article SR Electronic T1 Cost of Asset Allocation in Equity Market: How Much Do Investors Lose Due to Bad Asset Class Design? JF The Journal of Portfolio Management FD Institutional Investor Journals SP 34 OP 44 DO 10.3905/jpm.2014.41.1.034 VO 41 IS 1 A1 Woo Chang Kim A1 Yongjae Lee A1 Yoon Hak Lee YR 2014 UL https://pm-research.com/content/41/1/34.abstract AB Many investors employ asset allocation, even though most are not really concerned about how their asset classification schemes affect investment performance. This article extensively examines the two most widely employed within-stock classifications: styles and industry classification. In order to explicitly measure current classifications’ performance levels, the authors introduce the concept of optimal asset classification, which provides the upper performance limit of any classification scheme. They find that style and industry classification are very costly. Furthermore, factor analysis reveals that the immediate cause of exorbitant cost lies in the method on which classification focuses.TOPICS: Equity portfolio management, in markets, exchanges/markets/clearinghouses
