Home bias no mercado de capitais brasileiro : um estudo sobre a custódia de investidores em ações

A presente dissertação apresenta uma análise da concentração do portfólio de a-ções de investidores brasileiros nas próprias empresas onde trabalham com o intuito de observar se o Home Bias se aplica à amostra analisada. Nosso estudo foi reali-zado com uma amostra extraída da custódia de 86 clientes de uma corretora de va-lores mobiliários, sendo estes dados reais de mercado. Restringimos a seleção da amostra de forma que metade fosse de clientes que trabalham em empresas de ca-pital aberto e a outra metade não. Foi feita análise cross section de quanto os inves-tidores alocam em ações das empresas para a qual trabalham e verificou-se qual o percentual desta participação em seus portfólios, em comparação a uma amostra de controle de investidores que não trabalham nesta mesma empresa. Além destas a-nálises, separamos a amostra pelo valor total do portfólio e realizamos os mesmos estudos com estes dois grupos diferentes da amostra. Como uma análise de robus-tez, identificamos empresas listadas que não adotam a remuneração com ações como uma sub-amostra do estudo. Como resultado, encontramos evidências de que os funcionários investem significativamente mais (seja em proporção do portfólio ou em valores) em ações das empresas onde trabalham em relação aos demais inves-tidores, evidenciando um viés de familiaridade na tomada de decisão de investimen-tos.

Local home bias: Theory and new empirical evidence from Italy

This thesis examines the literature on local home bias, i.e. investor preference towards geographically nearby stocks, and investigates the role of firm’s visibility, profitability, and opacity in explaining such behavior. While firm’s visibility is expected to proxy for the behavioral root originating such a preference, firm’s profitability and opacity are expected to capture the informational one. I find that less visible, and more profitable and opaque firms, conditionally to the demand, benefit from being headquartered in regions characterized by a scarcity of listed firms (local supply of stocks). Specifically, research estimates suggest that firms headquartered in regions with a poor supply of stocks would be worth i) 11 percent more if non-visible, non-profitable and non-opaque; ii) 16 percent more if profitable; and iii) 28 percent more if both profitable and opaque. Overall, as these features are able to explain most, albeit not all, of the local home bias effect, I reasonably argue and then assess that most of the preference for local is determined by a successful attempt to exploit local information advantage (60 percent), while the rest is determined by a mere (irrational) feeling of familiarity with the local firm (40 percent). Several and significant methodological, theoretical, and practical implications come out.

Education and the local equity bias around the world

Using a panel of 38 economies, over the period 2001 to 2010, we analyse the link between different facets of education and diversification in international portfolios. We find that university education, mathematical numeracy, in addition to financial skill, play an important role in reducing home bias. After separating countries according to their level of financial development, we find that less developed economies with more university graduates, or with higher level of mathematical numeracy, have lower level of local equity bias compared to more developed countries. We also find that the beneficial effect of education is more pronounced during the most recent financial crisis, especially for economies with less developed financial markets.

The role of education in equity portfolios during the recent financial crisis

Using a panel of 38 economies, over the period 2001 to 2010, we analyse the link between diversification in equity portfolios and different facets of education. We find that traditionally used measures of education play an important role in reducing equity home bias. After separating countries according to their level of financial development, we find that less developed economies tend to benefit more from an improvement in the level of education compared to their more developed counterparts. We also find that the beneficial effect of education is more pronounced during the most recent financial crisis, especially for economies with less developed financial markets.

A New open economy macroeconomic model with endogenous portfolio diversification and firms entry

This paper provides a new benchmark for the analysis of the international diversi…cation puzzle in a tractable new open economy macroeconomic model. Building on Cole and Obstfeld (1991) and Heathcote and Perri (2009), this model speci…es an equilibrium model of perfect risk sharing in incomplete markets, with endogenous portfolios and number of varieties. Equity home bias may not be a puzzle but a perfectly optimal allocation for hedging risk. In contrast to previous work, the model shows that: (i) optimal international portfolio diversi…cation is driven by home bias in capital goods, independently of home bias in consumption, and by the share of income accruing to labour. The model explains reasonably well the recent patterns of portfolio allocations in developed economies; and (ii) optimal portfolio shares are independent of market dynamics.

Free Flows, Limited Diversification: Explaining the Fall and Rise of Stock Market Correlations, 1890-2001

Using a new dataset on capital account openness, we investigate why equity return correlations changed over the last century. Based on a new, long-run dataset on capital account regulations in a group of 16 countries over the period 1890-2001, we show that correlations increase as financial markets are liberalized. These findings are robust to controlling for both the Forbes-Rigobon bias and global averages in equity return correlations. We test the robustness of our conclusions, and show that greater synchronization of fundamentals is not the main cause of increasing correlations. These results imply that the home bias puzzle may be smaller than traditionally claimed.

Retos y alternativas de inversión para las compañías aseguradoras en Colombia

En este documento se explica el rol de las compañías aseguradoras colombianas dentro del sistema pensional y se busca, a través de la comprensión de la evolución del entorno macroeconómico y del marco regulatorio, identificar los retos que enfrentan. Los retos explicados en el documento son tres: el reto de la rentabilidad, el reto que plantean los cambios relativamente frecuentes de la regulación, y el reto del “calce”. El documento se enfoca principalmente en el reto de la rentabilidad y desarrolla un ejercicio de frontera eficiente que utiliza retornos esperados calculados a partir de la metodología de Damodaran (2012). Los resultados del ejercicio soportan la idea de que en efecto los retornos esperados serán menores para cualquier nivel de riesgo y sugiere que ante tal panorama, la relajación de las restricciones impuestas por el Régimen de inversiones podría alivianar los preocupaciones de las compañías aseguradoras en esta materia. Para los otros dos retos también se sugieren alternativas: el Algorithmic Trading para el caso del reto que impone los cambios en la regulación, y las Asociaciones Público-Privadas para abordar el reto del “calce”.

Brazilian international and inter-state trade flows: an exploratory analysis using the gravity model

Recent efforts toward a world with freer trade, like WTO/GATT or regional Preferential Trade Agreements(PTAs), were put in doubt after McCallum's(1995) finding of a large border effect between US and Canadian provinces. Since then, there has been a great amount of research on this topic employing the gravity equation. This dissertation has two goals. The first goal is to review comprehensively the recent literature about the gravity equation, including its usages, econometric specifications, and the efforts to provide it with microeconomic foundations. The second goal is the estimation of the Brazilian border effect (or 'home-bias trade puzzle') using inter-state and international trade flow data. It is used a pooled cross-section Tobit model. The lowest border effect estimated was 15, which implies that Brazilian states trade among themselves 15 times more than they trade with foreign countries. Further research using industry disaggregated data is needed to qualify the estimated border effect with respect to which part of that effect can be attributed to actual trade costs and which part is the outcome of the endogenous location problem of the firm.

Preferências de ações de gestores de fundos mútuos estrangeiros na América Latina

Nesse trabalho são observadas as características preferencias dos gestores de fundos mútuos estrangeiros ao selecionar ações na América Latina. O objetivo foi verificar a hipótese de que esses gestores preferem companhias que possuam características que geram grande visibilidade, ou seja, que reduzam a assimetria de informação, uma das possíveis explicações para a existência do home bias. Para isso, foram observadas as posições dos fundos mútuos a partir das listas de acionistas das companhias listadas nas bolsas dos países da amostra em três períodos diferentes (junho de 2008, 2009 e 2010). A análise revela que essa classe de investidores prefere companhias que possuam atributos que ampliem seu contato com mercados internacionais, tais quais, a listagem internacional, maior cobertura de analistas e que façam parte de setores exportadores, reforçando a ideia de que a assimetria de informação reduz a capacidade de seleção de ativos por parte dos participantes de mercado e, portanto, justificando a teoria do home bias. O estudo ainda compara as preferências dos gestores estrangeiros com gestores domiciliados na América Latina e mostra evidências de que os gestores de fundos mútuos domésticos possuem maior dispersão de investimentos nas companhias listadas e, consequentemente, possuem preferências diferentes daquelas observadas para os gestores estrangeiros.

Diversificação internacional no contexto brasileiro

Este trabalho contribui a discussão de diversificação internacional no contexto de investidores brasileiros com referência na moeda local (Reais). O trabalho testa as seguintes hipóteses: (1) se a adição de ativos internacionais não aumenta a eficiência (melhora na relação retorno/risco) de carteiras somente com ativos brasileiros, (2) se carteiras de menor risco exigem mais alocações internacionais e, (3) se alocação de ativos é parecida para investidores com referências em dólar ou em reais. Esse trabalho utiliza modelos já conhecidos de fronteiras eficientes com aplicação de técnicas que utilizam rotinas de Monte Carlo para suavizar possíveis erros na estimação dos retornos das classes de ativos, que incorporam ainda incertezas sobre o câmbio. Nas simulações são utilizadas uma cesta de ativos locais e uma cesta de ativos que melhor representa o mercado internacional. Apesar da grande maioria dos investidores brasileiros utilizarem muito pouco ativos internacionais em suas carteiras, seja por motivos de Home Bias, fatores históricos macroeconômicos evidenciados pelas altas taxas de juros ou limitações regulatórias, os resultados empíricos demonstram que existem ganhos de eficiência para as carteiras de investidores brasileiros ao se incluir ativos internacionais na alocação de ativos. Esses ganhos de eficiência são evidenciados para todos os perfis de risco, desde os mais conservadores até os perfis mais agressivos. Os resultados mostram que quanto maior o perfil de risco da carteira, maior é a alocação internacional que maximiza a eficiência da carteira. E por último, a referência da moeda muda significativamente a alocação eficiente de carteiras, carteiras com referência em dólar exigem menos diversificação com ativos em reais do que carteiras com referência em Reais exigem diversificação com ativos internacionais.

Framing Banking Union in the Euro Area: Some empirical evidence. CEPS Working Document No. 389, 3 February 2014

Evidence shows that financial integration in the euro area is retrenching at a quicker pace than outside the union. Home bias persists: Governments compete on funding costs by supporting ‘their’ banks with massive state aids, which distorts the playing field and feeds the risk-aversion loop. This situation intensifies friction in credit markets, thus hampering the transmission of monetary policies and, potentially, economic growth. This paper discusses the theoretical foundations of a banking union in a common currency area and the legal and economic aspects of EU responses. As a result, two remedies are proposed to deal with moral hazard in a common currency area: a common (unlimited) financial backstop to a privately funded recapitalisation/resolution fund and a blanket prohibition on state aids.

Theory of foreign portfolio investment

This dissertation examines one category of international capital flows, private portfolio investments (private refers to the source of capital). There is an overall lack of a coherent and consistent definition of foreign portfolio investment. We clarify these definitional issues.^ Two main questions that pertain to private foreign portfolio investments (FPI) are explored. The first problem is the phenomenon of home preference, often referred to as home bias. Related to this are the observed cross-investment flows between countries that seem to contradict the textbook rendition of private FPI. A description of the theories purporting to resolve the home preference puzzle (and the cross-investment one) are summarized and evaluated. Most of this literature considers investors from major developed countries. I consider--as well--whether investors in less developed countries have home preference.^ The dissertation shows that home preference is indeed pervasive and profound across countries, in both developed and emerging markets. For the U.S., I examine home bias in both equity and bond holdings as well. I find that home bias is greater when we look at equity and bond holdings than equity holdings solely.^ In this dissertation a model is developed to explain home bias. This model is original and fills a gap in the literature as there have been no satisfactory models that handle at the same time both home preference and cross-border holdings in the context of information asymmetries. This model reflects what we see in the data and permits us to reach certain results by the use of comparative statics methods. The model suggests, counter-intuitively, that as the rate of return in a country relative to the world rate of return increases, home preference decreases. In the context of our relatively simple model we ascribe this result to the higher variance of the now higher return for home assets. We also find, this time as intended, that as risk aversion increases, investors diversify further so that home preference decreases.^ The second question that the dissertation deals with is the volatility of private foreign portfolio investment. Countries that are recipients of these flows have been wary of such flows because of their perceived volatility. Often the contrast is made with the perceived absence of volatility in foreign direct investment flows. I analyze the validity of these concerns using first net flow data and then gross flow data. The results show that FPI is not, in relative terms, more volatile than other flows in our sample of eight countries (half were developed countries and the rest were emerging markets).^ The implication therefore is that restricting FPI flows may be harmful in the sense that private capital may not be allocated efficiently worldwide to the detriment of capital poor economies. More to the point, any such restrictions would in fact be misguided. ^
