Turnover-Adjusted Information Ratio

  title={Turnover-Adjusted Information Ratio},
  author={Feng Zhang and Xi Wang and Honggao Cao},
In this paper, we study the behavior of information ratio (IR) as determined by the fundamental law of active investment management. We extend the classic relationship between IR and its two determinants (i.e., information coefficient and investment “breadth”) by explicitly and simultaneously taking into account the volatility of IC and the cost from portfolio turnover. Through mathematical derivations and simulations, we show that – for both mean-variance and quintile portfolios – a turnover… Expand

Information Horizon, Portfolio Turnover, and Optimal Alpha Models
The net value-added of an investment strategy has two parts: the expected value of the alpha skill, and the cost of implementation. The first part is positive and depends on the efficacy of a returnExpand
Portfolio Turnover Activity and Mutual Fund Performance
We propose a new measure of portfolio activity, the Modified Turnover, which represents the portion of the portfolio that the manager changes from one quarter to the next. Compared with theExpand
Portfolio turnover when IC is time-varying
We develop new formulas for the turnover and leverage of mean–variance optimal long–short market neutral portfolios, where active weights are obtained using a factor model conditional mean forecastExpand
Performance v. Turnover: A Story by 4,000 Alphas
We analyze empirical data for 4,000 real-life trading portfolios (U.S. equities) with holding periods of about 0.7-19 trading days. We find a simple scaling C ~ 1/T, where C is cents-per-share, and TExpand
One of the underlying assumptions of the Fundamental Law of Active Management is that the active risk of an active investment strategy equates estimated tracking error by a risk model. We show thereExpand
The Fundamental Law of Active Management: Redux
We develop a fundamental law of active management based on cross-section factor models for residual returns where the latter have unconditional mean zero and the factor exposures have zero mean andExpand
The Common Factor in Idiosyncratic Volatility: Quantitative Asset Pricing Implications
We show that firms’ idiosyncratic volatility obeys a strong factor structure and that shocks to the common factor in idiosyncratic volatility (CIV) are priced. Stocks in the lowest CIV-beta quintileExpand
The Idiosyncratic Volatility Puzzle: Time Trend or Speculative Episodes?
Campbell, Lettau, Malkiel, and Xu (2001) document a positive trend in idiosyncratic volatility during the 1962--1997 period. We show that by 2003 volatility falls back to pre-1990s levels.Expand
Integrated Alpha Modeling
Alpha modelling typically refers to the selection and weighting of various information sources, which when combined are used by active portfolio managers to forecast security returns. It isExpand
Shedding Light on “Invisible” Costs: Trading Costs and Mutual Fund Performance
Industry observers have long warned of the “invisible” costs of fund trading, yet evidence that these costs matter is mixed because many studies do not account for the largest trading-costExpand
