We show that a mutual fund's stock selection skill can be decomposed into additional components that include impatient quot;informed tradingquot; and quot;liquidity provision.quot; We validate our method by verifying that liquidity providing trades are the primary source of value for the...

The relative predictability of returns and dividends is a central issue since it forms the paradigm to interpret asset price variation. A little studied question is how dividend smoothing, as a choice of corporate policy, affects predictability. We show that, even if dividends are supposed to be...

We find the disparity between long-term and short-term analyst forecasted earnings growth is a robust predictor of future returns and revisions in long-term forecasted earnings growth. After adjusting for industry characteristics, stocks whose long-term earnings growth forecasts are far above or...

This paper employs a new VaR approach due to...

Robust optimization, one of the most popular topics in the field of optimization and control since the late 1990s, deals with an optimization problem involving uncertain parameters. In this paper, we consider the relative robust conditional value-at-risk portfolio selection problem where the...
