Resumo: | This thesis aims to explore possible conflicts of interest between the activities of agents in the Brazilian financial market, especially banks, investment funds and analysts. In the first chapter, the focus is the possible lack of a Chinese Wall between the investment banking activities and the asset management unit of the same bank during the bond underwriting process. The conflict of interest analyzed is the possible use of funds under management of the same bank to allocate bond issuances that would not have sufficient demand in the market. The paper proposes an empirical study of bonds issued in Brazil between 2005 and 2015. The results show that bond 'excess return' at the time of issuance is negative when there is allocation of funds associated with the underwriter, supporting the thesis of conflict of interest. However, when the associated funds are for Institutional Investors, the 'excess return' is positive indicating that the better monitoring of the fund's activities could serve as mitigation for the conflict of interest. In the second chapter the assessed conflict of interest is the funding activities of banks and the rates obtained by investment funds from fixed income assets issued by banks. The hypothesis tested is that affiliated funds obtain a lower yield than non-affiliated funds on the same assets. To test this hypothesis, an empirical study was conducted in Brazil with the rates of Letra Financeira, from the beginning of its emergence in 2010 until the end of 2015. The results point that funds, when investing in Letras Financeiras of the controlling bank, obtain a lower yield than that obtained by funds not affiliated to the same bank. However, like the results obtained in the previous chapter, this effect is not observed in funds for Institutional Investors. Corroborating the idea that better monitoring can mitigate the conflict of interest involved. Finally, the third chapter analyzes two possible conflicts of interest derived from the relationship between the opinions of stock analysts and the investments of the funds affiliated to the same bank. The first hypothesis is about optimism of the analysts as the affiliated funds have a large volume of investment in the stock. The second hypothesis is about Front Running, where funds anticipate changes in analysts' opinions of the same bank. The database used in this study was the opinion of all analysts covering Brazilian stocks for 10 years, from 2005 to 2015. The results suggest that: (i) there is an optimism of analysts associated with Brazilian banks related to the volume invested by affiliated funds, and (ii) the evidence does not support the hypothesis of front running by the funds. |

No primeiro capítulo, analisa-se o conflito de interesse da possível falta de um Chinese Wall entre as operações de banco de investimento e a área de fundos de investimento de um mesmo banco durante o processo de emissão de debêntures. O conflito de interesse analisado é a possível utilização dos fundos de investimentos sob a gestão do banco coordenador para alocar emissões que não teriam demanda suficiente no mercado. Para analisar este conflito de interesse foi realizado um estudo empírico das emissões de debêntures realizadas no Brasil entre 2005 e 2015. Os resultados mostram que o ‘retorno em excesso’ das debêntures no momento de emissão é negativo quando há alocação dos fundos de investimento associados ao banco coordenador da emissão, indicando a possibilidade do conflito de interesse. Porém, quando os fundos associados são destinados a Investidores Qualificados, o ‘retorno em excesso’ é positivo indicando que o possível melhor monitoramento das atividades do fundo serve de mitigador para o conflito de interesse. No segundo capítulo o conflito de interesse avaliado são as atividades de captação dos bancos e as taxas obtidas pelos fundos de investimento nos ativos de renda fixa emitidos pelos bancos. A hipótese testada é que o fundo associado aos bancos obtém uma taxa de retorno menor que os fundos não associados nos mesmos ativos emitidos por estes bancos. Para avaliar esta hipótese foi realizado um estudo empírico no Brasil com as taxas das Letras Financeiras, desde o início de seu surgimento em 2010 até o final de 2015. Os resultados apontam que os fundos, ao investirem em Letras Financeiras do banco controlador, obtém uma taxa menor que a obtida por outros fundos em Letras Financeiras deste mesmo banco. Porém, assim como os resultados obtidos no capítulo anterior, este efeito não é observado em fundos destinados a Investidores Qualificados, o que corrobora a ideia de que um melhor monitoramento pode mitigar o conflito de interesses envolvido. Por fim, no terceiro capítulo, são analisados dois possíveis conflitos de interesse derivados da relação entre as opiniões dos analistas de ações e os investimentos dos fundos do mesmo banco. O primeiro conflito é sobre o otimismo dos analistas conforme os fundos associados ao mesmo banco possuem um grande volume de investimento nas ações avaliadas. O segundo conflito é sobre o Front Running, onde os fundos obtem retornos antecipando as mudanças de opiniões dos analistas relacionados ao mesmo banco. Foram avaliadas as opiniões de todos os analistas que cobrem as ações brasileiras por 10 anos. Os resultados sugerem que: (i) existe um indicativo de otimismo dos analistas associados aos bancos brasileiros quanto maior o volume de recursos aplicado pelos fundos associados e que (ii) as evidências não dão suporte à hipótese de front running por parte dos fundos.engFinancial marketsConflicts of interestFinanceFinancial institutionsMercado financeiroConflitos de

description |
This thesis aims to explore possible conflicts of interest between the activities of agents in the Brazilian financial market, especially banks, investment funds and analysts. In the first chapter, the focus is the possible lack of a Chinese Wall between the investment banking activities and the asset management unit of the same bank during the bond underwriting process. The conflict of interest analyzed is the possible use of funds under management of the same bank to allocate bond issuances that would not have sufficient demand in the market. The paper proposes an empirical study of bonds issued in Brazil between 2005 and 2015. The results show that bond 'excess return' at the time of issuance is negative when there is allocation of funds associated with the underwriter, supporting the thesis of conflict of interest. However, when the associated funds are for Institutional Investors, the 'excess return' is positive indicating that the better monitoring of the fund's activities could serve as mitigation for the conflict of interest. In the second chapter the assessed conflict of interest is the funding activities of banks and the rates obtained by investment funds from fixed income assets issued by banks. The hypothesis tested is that affiliated funds obtain a lower yield than non-affiliated funds on the same assets. To test this hypothesis, an empirical study was conducted in Brazil with the rates of Letra Financeira, from the beginning of its emergence in 2010 until the end of 2015. The results point that funds, when investing in Letras Financeiras of the controlling bank, obtain a lower yield than that obtained by funds not affiliated to the same bank. However, like the results obtained in the previous chapter, this effect is not observed in funds for Institutional Investors. Corroborating the idea that better monitoring can mitigate the conflict of interest involved. Finally, the third chapter analyzes two possible conflicts of interest derived from the relationship between the opinions of stock analysts and the investments of the funds affiliated to the same bank. The first hypothesis is about optimism of the analysts as the affiliated funds have a large volume of investment in the stock. The second hypothesis is about Front Running, where funds anticipate changes in analysts' opinions of the same bank. The database used in this study was the opinion of all analysts covering Brazilian stocks for 10 years, from 2005 to 2015. The results suggest that: (i) there is an optimism of analysts associated with Brazilian banks related to the volume invested by affiliated funds, and (ii) the evidence does not support the hypothesis of front running by the funds. |
