In this paper, we identify and document the empirical characteristics of the key drivers of convertible arbitrage as a strategy and how they impact the performance of convertible arbitrage hedge funds. We show that the returns of a buy-and-hedge strategy involving taking a long position in convertible bonds (“CBs”) while hedging the equity risk alone explains a substantial amount of these funds' return dynamics. In addition, we highlight the importance of non-price variables such as extreme market-wide events and the supply of CBs on performance. Out-of-sample tests provide corroborative evidence on our model's predictions. At a more micro level, larger funds appear to be less dependent on directional exposure to CBs and more active in shorting stocks to hedge their exposure than smaller funds. They are also more vulnerable to supply shocks in the CB market. These findings are consistent with economies of scale that large funds enjoy in accessing the stock loan market. However, the friction involved in adjusting the stock of risk capital managed by a large fund can negatively impact performance when the supply of CBs declines. Taken together, our findings are consistent with convertible arbitrageurs collectively being rewarded for playing an intermediation role of funding CB issuers whilst distributing part of the equity risk of CBs to the equity market.  相似文献

We use the Chinese initial public offering data from October 2009 to August 2010 to examine the newly‐established growth enterprise board (GEB). The results indicate that the GEB has been successful and is providing a viable channel for new small and medium‐sized firms to raise external capital. Four variables, the volatility variable, the turnover ratio, the winning lottery ratio and the price–earnings ratio, are important factors driving the initial‐day returns in the regression analysis. The implementation of the new trading‐halts policy on the GEB is found to be effective in mitigating excessive speculation. Our analysis results could be used by policy‐makers to gauge the effects of policy changes on the underpricing of the initial public offerings of the GEB.  相似文献

The volume of air passengers and cargo in the Asia‐Pacific region has grown significantly over the past decade due to the strong impetus of economic growth as well as trade and economic integration at both the regional and global levels. Although public funds have been the main source of financing for airports in most parts of the region, governments have increasingly resorted to privatization or are seriously considering it as a form of private sector participation enabling new airports to be built or existing airports to be upgraded. The present paper provides a brief survey of airport privatization in the Asia‐Pacific region, discusses the relevant issues, and introduces the following five papers published in this special section on the air transport industry in the Asia‐Pacific region.  相似文献

We propose a more elaborate model on berth allocation considering fuel consumption than before, and overcome the nonlinear complexity by casting it as a mixed integer second order cone programming model. Furthermore, we conduct the vessel emission (in sailing periods) calculation with the widely-used emission factors. Besides, vessel emissions in mooring periods are also analyzed through a post-optimization phase on waiting time. Experimental results demonstrate that the new berth allocation strategy, reflected by the proposed model, is competent to significantly reduce fuel consumption and vessel emissions, while simultaneously retaining the service level of the terminal.  相似文献

This study investigates the effect of institutional ownership on improving firm efficiency of equity Real Estate Investment Trusts (REITs), using a stochastic frontier approach. Firm inefficiency is estimated by comparing a benchmark Tobin??s Q of a hypothetical value-maximizing firm to the firm??s actual Q. We find that the average inefficiency of equity REITs is around 45.5%, and that institutional ownership can improve the firm??s corporate governance, and hence reduce firm inefficiency. Moreover, we highlight the importance of heterogeneity in institutional investors??certain types of institutional investors such as long-term, active, and top-five institutional investors, and investment advisors are more effective institutional investors in reducing firm inefficiency; whereas hedge funds and pension funds seem to aggravate the problem. In sub-sample analysis, we find that these effective institutional investors can reduce inefficiency more effectively for distressed REITs, and for REITs with high information asymmetry, and with longer term lease contracts. Lastly, we find that the negative impact of institutional ownership (except for long-term institutional investors) on firm inefficiency reduces over time, possibly due to strengthened corporate governance and regulatory environment in the REIT industry.  相似文献

The risk in hedge fund strategies: theory and evidence from trend followers   总被引:3,自引:0,他引:3  
Hedge fund strategies typically generate option-like returns.Linear-factor models using benchmark asset indices have difficultyexplaining them. Following the suggestions in Glosten and Jagannathan(1994), this article shows how to model hedge fund returns byfocusing on the popular 'trend-following' strategy. We use lookbackstraddles to model trend-following strategies, and show thatthey can explain trend-following funds' returns better thanstandard asset indices. Though standard straddles lead to similarempirical results, lookback straddles are theoretically closerto the concept of trend following. Our model should be usefulin the design of performance benchmarks for trend-followingfunds.  相似文献

The property of non-invariance to the scale of the data for the Abraham and Box (1978) Bayesian outlier model, and the model that generalizes the Guttman, Dutter and Freeman (1978) outlier analysis is discussed. This drawback is due to the non-informative prior taken for the parameters. Freeman (1980) expected that most posterior weight would be put on the model with the most outliers if the improper prior is used. We show that this may not be correct. An illustrative example is given.  相似文献

Effects of electronic trading on the Hang Seng Index futures market   总被引:1,自引:1,他引:0  
This investigation of the switch from open-outcry trading to electronic trading on the Hang Seng Index (HSI) futures contract reveals that the bid–ask spread narrows and the futures price plays more of a role in information transmission. Factors, such as anonymity in trading and fast order execution in electronic trading, attract informed traders to the futures market, enhancing the information flow. Our results provide support for the worldwide trend of transforming open-outcry markets into electronic trading platforms.  相似文献

Older adults constitute a rapidly growing demographic segment, but relatively little is known about them within consumer contexts: how they process information, respond to persuasive messages, and make decisions. We discuss extant findings from consumer behavior and related disciplines (e.g., cognitive psychology, neuroscience, social psychology, gerontology) as they pertain to the effects of aging on consumer memory, persuasion and decision The first two authors co-chaired the workshop at the Choice Symposium and made major and equal contributions to this article. The remaining authors were participants in the workshop. They also contributed to this article and are listed in alphabetical order. We wish to thank the editor and Cathy Cole for their helpful comments on the paper. The article, including a more complete list of references, was shortened to meet the page-length constraints of the special issue. The longer version is available upon request from the senior authors.  相似文献

This study examines the intraday trading activities of index stocks on the common expiration day of index derivatives. In Hong Kong, index futures and index options use an Asian‐style settlement procedure. All contracts are settled against the estimated average settlement price, an arithmetic average of the underlying cash index taken every five minutes on the expiration day. Trading volume and total trade count on the expiration day are both found to be higher than normal. Most important, trading intensifies in terms of volume and frequency close to the five‐minute time marks. The study does not find significant price reversal and price compression patterns. Although significant order imbalance pattern is found on some expiration days, the results show no association between order imbalance pattern and the next‐day return. © 2009 Wiley Periodicals, Inc.
