| Abstract |
|
We introduce two activeness measures as proxies for private information which fund managers may possess. They are from portfolio information and represent common factor activeness and individual stocks activeness respectively. To address the collinearity between those measures, we invent a scheme to extract Pure Active Position (PAP) from Dirty Active Position (DAP) with the perspective of top-down portfolio management. It is showed that DAP from industry and PAP from stocks conditioned on the DAP effectively explain the excess returns of funds or hypothetical portfolios. Also they have robustness relative to some alternative measures derived from styles and stocks and/or with a view of bottom-up approach. With no requirement of time-series data, distinct to those previous studies such as Cremers and Petajisto (2009) and so on, our measures would be specially appropriate to the Korean asset management industry in which funds are easily launched and have a relatively shorter life. |
