Some commentators attribute the success of certain hedge fund activism events to “wolf pack” activism, the support offered by other investors, many of whom are thought to accumulate stakes in the target firms before the activists’ campaigns are publicly disclosed. This paper investigates wolf-pack activism by considering the following questions: Is there any evidence of wolf-pack formation? Is the wolf pack formed intentionally (by the lead activist) or does it result from independent activity by other investors? Does the presence of a wolf pack improve the activist’s ability to achieve its stated objectives? First, I find that investors other than the lead activist do in fact accumulate significant share-holdings before public disclosure of activists’ campaigns, a result consistent with wolf-pack formation. Second, these share accumulations are more likely to be mustered by the lead activist rather than occurring spontaneously. Notably, for example, the other investors are more likely to be those who had a prior trading relationship with the lead activist. Third, the presence of a wolf pack is associated with a greater likelihood that the activist will achieve its stated objectives (e.g., will obtain board seats) and higher future stock returns over the duration of the campaign.

This thesis examines the degree to which alternative funds deviate from their style-benchmark and how this is related to past performance and fund size, and how it impacts future risk and returns. Additionally the thesis examines how security selection and market timing skills differ across varying degrees of deviation from the benchmark. The thesis uses data for hedge funds, funds of funds, and CTA funds from the Center for International Securities and Derivatives Markets and employs fund???s tracking error relative to their style-benchmark to estimate the level of drift. The style-benchmarks used are the median return for all reporting funds that follow a particular style and funds are assigned a benchmark based on their self-reported style. First, this thesis documents statistically significant differences in the tracking errors of portfolios of funds with the highest tracking error versus funds with the lowest tracking error, implying that some managers drift from their self-reported style-benchmarks. Second, funds??? benchmark-inconsistency is less severe in the case of funds that have a regulatory obligation to disclose their performance, suggesting that the absence of regulation fosters an environment where managers can be more flexible with their investment approach. Third, the tendency to drift from the benchmark is most prevalent amongst funds with superior past performance as well as small funds. Fourth, future total portfolio risk increases as funds display more benchmarkinconsistency, suggesting that managers adopt riskier strategies as they attempt to enhance returns. Fifth, the thesis demonstrates that CTA funds that display drift from their benchmark produce higher absolute and relative returns in subsequent periods regardless of the direction of the general market. In contrast, the findings show for hedge funds and funds of funds, benchmark-inconsistent funds are likely to outperform in bull markets and underperform in bear markets. Finally, this thesis shows that more benchmark-consistent managers have better security selection skill. The main contribution of this thesis is in identifying the group of hedge funds, funds of funds, and CTA funds that are likely to deviate from their self-reported style-benchmark and the risk-return consequences of such deviations. The findings have implications for investors and regulators.

The purpose of this study is to analyze Swedish hedge funds in terms of pursued investment strategies, risks and returns. The study deals with a large number of quantitative data and delimitations were used to obtain a sample that better fulfills the purpose of this paper. The time frame chosen for increas-ing validity and reliability was almost four years. Furthermore, the study uses secondary data due to difficulties and costs as-sociated with obtaining primary data though this is not consi-dered as lowering the quality of the study. The theory section starts by presenting the differences between hedge funds and mutual funds and then focusing on different hedge fund strategies, risks associated with hedge funds and fi-nally risk and return measurements. This section provides an overview for the empirical findings and analysis. In the empirical findings and analysis, statistical calculations of and Analysis the risk measurements standard deviation, Sharpe ratio, track-ing error and correlation are conducted for the sample. The re-sults are related to the hedge funds strategies. Later on the strategies are weighted against each other. Finally, all strategies are compared to OMXS to find the investors‟ most appropriate investment structure. After categorizing the different hedge funds with respect to pursued strategies, the result shows how there are clear dispari-ties in risk and returns for the different strategies. We found indications of a significant relationship between high return and high risk as well as between low return and low risk.

This paper explores the economic rationales underpinning potential hedge fund regulation, and reviews the arguments about why rules aimed to mitigate systemic risk may be economically efficient. The paper presents a limited definition of systemic risk, and proposes that an international macro-prudential supervisory body be set up for the Ontario, U.S. and U.K. markets to collect systemically important information about hedge funds and to recommend policy changes in light of this information. The paper also reviews the proposed regulatory reforms in the United States that will apply to hedge funds, and argues that while helpful, such regulations are sub-optimal because they do not consider certain important characteristics of systemic risk.

What explains the shift towards greater direct public oversight of financial markets in international financial regulation that has characterized the response to the global financial crisis of 2007-2010? Over this period, the main international financial regulatory bodies have abandoned the market-based mechanisms that had informed their approach towards the regulation of different financial domains in the years before the crisis and significantly expanded the perimeter of state-based regulation. However, the extent and the timing of this shift cannot be regarded only as the by-product of the crisis, nor they can be explained by the existing interpretations of the political determinants of international regulatory policies. This study builds upon existing state-centric explanations of international regulatory policies, but it goes beyond these works by exploring how the preferences of the most influential countries in response to the crisis have been influenced by variations in the degree of public salience of different financial domains. More specifically, this study argues that the lasting increase in the public salience of financial regulatory policies in the US and different European countries since the last quarter of 2008 has created strong incentives for elected officials in these countries to challenge the market-based approach that had emerged in the decade and half before the crisis and to directly interfere in the international regulatory agenda. In order to explain this shift, this study will analyse the evolution in the international governance of three sets of markets and institutions that have occupied an important position in the international regulatory agenda in recent years: 1) OTC derivatives; 2) rating agencies; 3) hedge funds. Besides making an empirical contribution to the literature on the politics of international financial regulation, this study also contributes theoretically to this literature by deepening our understanding of the nexus between international regulatory coordination and domestic public opinion.
