Most previous studies demonstrating the influential role of the textual information released by the media on stock market performance have concentrated on earnings-related disclosures. By contrast, this paper focuses on disposal announcements, so that the impacts of listed companies’...

We study the empirical performance of the classical minimum-variance hedging strategy, comparing several econometric models for estimating hedge ratios of crude oil, gasoline and heating oil crack spreads. Given the great variability and large jumps in both spot and futures prices, great care is...

The majority of risk adjusted performance measures (RAPM) currently in use – e.g., Treynor ratio, (?/?)) ratio, Omega index, RoVaR, ‘coherent’ preference criteria, etc. – are incompat- ible with any sensible utility function and would be best avoided. We argue instead for the assessment...

Generalizations of traditional preference criteria such as the Sharpe ratio, the information ratio and the Jensen alpha are obtained by maximizing a certain equivalent excess return (CER) under relevant investment conditions. They are increasing functions of CERs and therefore equivalent...

This paper presents an empirical study of hedging the four largest US index exchange traded funds (ETFs). When hedging each ETF position with its own index futures we find that it is difficult to improve on the naïve 1:1 futures hedge, that hedging is less effective around the time of dividend...

The advent of index tracking early in the 1970s and the continuous growth of assets tied to the S&P 500 index have enforced perceptions of the importance of becoming an index-member, due to increased demand by index fund participants for the stocks involved in index composition changes. This...

This empirical study examines the impact of both advanced electronic trading platforms and index exchange traded funds (ETFs) on the minimum variance hedging of stock indices with futures. Our findings show that minimum variance hedging may provide an out-of-sample hedging performance that is...

This study examines the abnormal returns, trading activity and long term performance of stocks that were added to the S&P 500 Index during the period 1990 to 2002. By using a three-factor pricing model that allows for firm size and value characteristics as well as market risk, we are able to...

This paper investigates the optimal short-term hedging of Exchange Traded Fund (ETF) portfolios with index futures. Using daily data from May 2000 to December 2004 on the four largest passive ETFs (the Spider, the Diamond, the Cubes and the Russell iShare) and their corresponding index futures...

With institutional investors increasingly involved in alternative investments, portfolio optimisation within a large universe of hedge funds has become a key area for research. This paper develops a portfolio construction model that is specifically designed for funds of hedge funds,...
