RT Journal Article SR Electronic T1 The Bad Arithmetic of Active Management JF The Journal of Portfolio Management FD Institutional Investor Journals SP 115 OP 122 DO 10.3905/jpm.2017.43.2.115 VO 43 IS 2 A1 Brian J. Jacobsen YR 2017 UL https://pm-research.com/content/43/2/115.abstract AB There is an ongoing debate over the merits of active portfolio management. Although this article does not settle that debate, the author helps frame issues related to whether active management can make sense for a particular individual or institution. By deconstructing William Sharpe’s “The Arithmetic of Active Management,” (Financial Analysts Journal 1991) a classic article in the active/passive debate, the author illustrates the various sources of value from active management and sheds light on the question of when active managers have a higher likelihood of outperforming or underperforming their benchmarks. Monetary policy is a key determinant; easy money can make investing hard for active managers.TOPICS: Manager selection, in portfolio management
