RT Journal Article SR Electronic T1 Analyzing Active Investment Strategies JF The Journal of Portfolio Management FD Institutional Investor Journals SP 56 OP 67 DO 10.3905/jpm.2006.661373 VO 33 IS 1 A1 Manuel Ammann A1 Stephan Kessler A1 Jürg Tobler YR 2006 UL https://pm-research.com/content/33/1/56.abstract AB Investors want to know the trading strategies an asset manager pursues to generate excess returns. Tracking error variance can be an alternative approach for analyzing the trading strategies used in active investing. Two decompositions of TEV may be used as a measure of activity in identifying different investment strategies. A simulation study testing the performance of different methods of strategy analysis demonstrates how a TEV decomposition can add information. When investment strategies involve random components, TEV decomposition delivers important additional information that traditional return decomposition methods cannot uncover.TOPICS: Equity portfolio management, quantitative methods, portfolio construction
