Hedge accounting no mercado acionário brasileiro : efeitos na qualidade da informação contábil e disclosure

Este trabalho investiga, no mercado acionário brasileiro, o efeito da contabilidade de hedge na qualidade das informações contábeis divulgadas, no disclosure dos instrumentos financeiros derivativos e na assimetria de informação. Para medir a qualidade da informação contábil, foram utilizadas as métricas de relevância da informação contábil e informatividade dos lucros contábeis. Para a execução deste trabalho, foi constituída uma amostra geral com empresas brasileiras, não financeiras, listadas na Bolsa de Valores de São Paulo, compreendendo as 150 empresas com maior valor de mercado em 01/01/2014. A partir da amostra geral, foram constituídas amostras para a aplicação dos modelos de value relevance, informativeness, disclosure e assimetria de informação. A amostra para relevância contou com 758 observações firmas-anos, para o período de 2008 a 2013. A amostra para informatividade contou com 701 observações firmas-anos, para o período de 2008 a 2013. A amostra para disclosure contou com 100 observações firmas-anos, para o período de 2011 a 2012. A amostra para assimetria de informação contou com 100 observações firmas-anos, para o período de 2011 a 2012. Para as análises dos dados, utilizou-se regressões com errospadrão robustos com abordagem POLS e Efeitos Fixos, aplicadas sobre dados em painel. Complementarmente, para as análises do efeito do hedge accounting sobre o disclosure e assimetria de informação, foi aplicado o método de Propensity Score Matching. As evidências encontradas para a influência da contabilidade de hedge na relevância da informação contábil apontaram uma relação positiva e significante na interação com o LL. Na análise da informatividade dos lucros contábeis, a pesquisa evidenciou uma relação negativa e estatisticamente significante do lucro quando interagido com a variável dummy de hedge accounting. Quanto às evidências encontradas para a influência do hedge accounting sobre o disclosure dos derivativos, verificou-se uma relação positiva e estatisticamente significante da dummy de hedge accounting com o indicador de evidenciação dos derivativos. Em relação às evidências para a assimetria de informação, embora os coeficientes se mostrassem no sentido esperado, os mesmos não foram estatisticamente significativos. Adicionalmente, incorporamse às análises econométricas uma análise descritiva, na amostra geral, da utilização do hedge accounting no Brasil, para o ano de 2013. Dentre as 150 empresas da amostra, 49 empresas utilizaram hedge accounting, onde 41 empresas adotam apenas 1 tipo de hedge. O hedge de fluxo de caixa é o tipo de hedge mais adotado pelas empresas, sendo utilizado por 42 companhias.

Private Governance of Financial Markets: the US Regulatory Regime on Hedge Funds

The article investigates the private governance of financial markets by looking at the evolution of the regulatory debate on hedge funds in the US market. It starts from the premise that the privatization of regulation is always the result of a political decision and analyzes how this decision came about and was implemented in the case of hedge funds. The starting point is the failure of two initiatives on hedge funds that US regulators launched between 1999 an 2004, which the analysis explains by elaborating the concept of self-capture. Facing a trade off between the need to tackle publicly demonized issues and the difficulty of monitoring increasingly sophisticated and powerful private markets, regulators purposefully designed initiatives that were not meant to succeed, that is, they “self-captured” their own activity. By formulating initiatives that were inherently flawed, regulators saved their public role and at the same time paved the way for the privatization of hedge fund regulation. This explanation identifies a link between the failure of public initiatives and the success of private ones. It illustrates a specific case of formation of private authority in financial markets that points to a more general practice emerging in the regulation of finance.

Hedge-rahastojen menestysmittaus

Tutkimuksen tavoitteena on selvittää miten hedge-rahastot eroavat ns. normaaleista osakerahastoista ja kuinka suomalaiset hedge-rahastot ovat pärjänneet tutkimusjaksolla 2003-2005. Tutkimuksen empiirisen osan aineisto on kerätty julkisesti saatavilla olevasta informaatiosta. Aineistoon on kerätty seitsemän suomalaista ja yksi ruotsalainen hedge-rahasto. Empiirinen osa mittaa rahastojen menestymistä siihen sopiviksi valituilla menestysmittareilla. Tulokset osoittavat, että suomalaiset hedge-rahastot ovat pärjänneet käytetyillä mittareilla tutkimusperiodilla verrattain huonosti. Tutkittavista rahastoista tutkimuksessa parhaiten menestyi ruotsalainen Erik Penser Hedge Fond.

Chasing performance persistence of hedge funds

The thesis examines the performance persistence of hedge funds using complement methodologies (namely cross-sectional regressions, quantile portfolio analysis and Spearman rank correlation test). In addition, six performance ranking metrics and six different combinations of selection and holding periods are compared. The data is gathered from HFI and Tremont databases covering over 14,000 hedge funds and time horizon is set from January 1996 to December 2007. The results suggest that there definitely exists performance persistence among hedge funds and the strength and existence of persistence vary among fund styles. The persistence depends on the metrics and combination of selection and prediction period applied. According to the results, the combination of 36-month selection and holding period outperforms other five period combinations in capturing performance persistence within the sample. Furthermore, model-free performance metrics capture persistence more sensitively than model-specific metrics. The study is the first one ever to use MVR as a performance ranking metric, and surprisingly MVR is more sensitive to detect persistence than other performance metrics employed.

Testing Futures Market Efficiency and Optimal Hedge Ratio Estimation: Evidence from Futures and Options on RTS

This study investigates futures market efficiency and optimal hedge ratio estimation. First, cointegration between spot and futures prices is studied using Johansen method, with two different model specifications. If prices are found cointegrated, restrictions on cointegrating vector and adjustment coefficients are imposed, to account for unbiasedness, weak exogeneity and prediction hypothesis. Second, optimal hedge ratios are estimated using static OLS, and time-varying DVEC and CCC models. In-sample and out-of-sample results for one, two and five period ahead are reported. The futures used in thesis are RTS index, EUR/RUB exchange rate and Brent oil, traded in Futures and options on RTS.(FORTS) For in-sample period, data points were acquired from start of trading of each futures contract, RTS index from August 2005, EUR/RUB exchange rate March 2009 and Brent oil October 2008, lasting till end of May 2011. Out-of-sample period covers start of June 2011, till end of December 2011. Our results indicate that all three asset pairs, spot and futures, are cointegrated. We found RTS index futures to be unbiased predictor of spot price, mixed evidence for exchange rate, and for Brent oil futures unbiasedness was not supported. Weak exogeneity results for all pairs indicated spot price to lead in price discovery process. Prediction hypothesis, unbiasedness and weak exogeneity of futures, was rejected for all asset pairs. Variance reduction results varied between assets, in-sample in range of 40-85 percent and out-of sample in range of 40-96 percent. Differences between models were found small, except for Brent oil in which OLS clearly dominated. Out-of-sample results indicated exceptionally high variance reduction for RTS index, approximately 95 percent.

Hedge-rahastojen menestyksen pysyvyyden empiirinen tarkastelu sijoittajan näkökulmasta

This study examines performance persistence of hedge funds from investor's point of view and look at the methods by which an investor could choose the successful hedge funds to the portfolio. This study was used the data from HFI & Tremont databases on period 1998-2007. In this study used the 36-month combination (24-month selection and 12-month prediction periods). As the research methods used the Sharpe index, raw returns, MVR (mean variance ratio), GSC-clustering, the SDI index and the new combination of metrics. The evaluation criterions of the results used the volatility, excess returns and the Sharpe index. This study compared different results from the 7 time series with each other, and commenting the problems on a portfolio loss of funds.

Hedge-rahastojen menestyksen pysyvyys ja suhteellinen suoriutuminen sijoittajan näkökulmasta

The purpose of the thesis is to examine the long-term performance persistence and relative performance of hedge funds during bear and bull market periods. Performance metrics applied for fund rankings are raw return, Sharpe ratio, mean variance ratio and strategy distinctiveness index calculated of the original and clustered data correspondingly. Four different length combinations for selection and holding periods are employed. The persistence is examined using decile and quartile portfolio formatting approach and on the basis of Sharpe ratio and SKASR as performance metrics. The relative performance persistence is examined by comparing hedge portfolio returns during varying stock market conditions. The data is gathered from a private database covering 10,789 hedge funds and time horizon is set from January 1990 to December 2012. The results of this thesis suggest that long-term performance persistence of the hedge funds exists. The degree of persistence also depends on the performance metrics employed and length combination of selection and holding periods. The best results of performance persistence were obtained in the decile portfolio analysis on the basis of Sharpe ratio rankings for combination of 12-month selection period and the holding period of equal length. The results also suggest that the best performance persistence occurs in the Event Driven and Multi strategies. Dummy regression analysis shows that a relationship between hedge funds and stock market returns exists. Based on the results, Dedicated Short Bias, Global Macro, Managed Futures and Other strategies perform well during bear market periods. The results also indicate that the Market Neutral strategy is not absolutely market neutral and the Event Driven strategy has the best performance among all hedge strategies.

ETF hedge - rahastojen suoriutuminen sijoittajan näkökulmasta aikavälillä 2009 – 2013

Tutkielmassa analysoidaan yhtä ETF rahastojen viimeisimpiä aluevaltauksia: ETF hedge-rahastoja, joista ensimmäiset saivat alkunsa vuonna 2009 finanssikriisin aiheuttamien sääntömuutosten johdosta. ETF hedge-rahastot imitoivat perinteisten hedge-rahastojen positioita tarkoituksenaan saavuttaa hedge-rahastojen perinteisesti suuret voitot, mutta ilman niille ominaista suurta kustannusrakennetta. Tutkimuksessa selvitetään, miten ETF hedge-rahastot ovat suoriutuneet Yhdysvaltain markkinoihin nähden, sekä miten nämä rahastot ovat onnistuneet hedge-rahastojen position imitoinnissa.
