Essays on Risk Aversion, Diversification and Non-Participation

My dissertation consists of three essays. The central theme of these essays is the psychological factors and biases that affect the portfolio allocation decision. The first essay entitled, “Are women more risk-averse than men?” examines the gender difference in risk aversion as revealed by actual investment choices. Using a sample that controls for biases in the level of education and finance knowledge, there is evidence that when individuals have the same level of education, irrespective of their knowledge of finance, women are no more risk-averse than their male counterparts. However, the gender-risk aversion relation is also a function of age, income, wealth, marital status, race/ethnicity and the number of children in the household. The second essay entitled, “Can diversification be learned?” investigates if investors who have superior investment knowledge are more likely to actively seek diversification benefits and are less prone to allocation biases. Results of cross-sectional analyses suggest that knowledge of finance increases the likelihood that an investor will efficiently allocate his direct investments across the major asset classes; invest in foreign assets; and hold a diversified equity portfolio. However, there is no evidence that investors who are more financially sophisticated make superior allocation decisions in their retirement savings. The final essay entitled, “The demographics of non-participation”, examines the factors that affect the decision not to hold stocks. The results of probit regression models indicate that when individuals are highly educated, the decision to not participate in the stock market is less related to demographic factors. In particular, when individuals have attained at least a college degree and have advanced knowledge of finance, they are significantly more likely to invest in equities either directly or indirectly through mutual funds or their retirement savings. There is also evidence that the decision not to hold stocks is motivated by short-term market expectations and the most recent investment experience. The findings of these essays should increase the body of research that seeks to reconcile what investors actually do (positive theory) with what traditional theories of finance predict that investors should do (normative theory).

Is Trading Behavior Stable Across Contexts? Evidence from Style and Multi-Style Investors

In this paper we study priming of identity within the context of inherent vs. contextual financial decision making. We use a sample of individual trading accounts in equity-style funds taken from one fund family to test the hypothesis that trading styles are inherent vs. contextual. Our sample contains investors who invest either in a growth fund, a value fund, or both. We document behavioral differences between growth fund investors and value fund investors. We find that their trades depend on past returns in different ways: growth fund investors tend towards momentum trading and value fund investors tend towards contrarian trading. These differences may be due to inherent clientele characteristics, including beliefs about market prices, specific personality traits and cognitive strategies that cause them to self-select into one or the other style. We use a sample of investors that trade in both types of funds to test this proposition. Consistent with the contextual hypothesis, we find that investors who hold both types of funds trade growth fund shares differently than value fund shares.

Asset Management and Investment Banking

We find evidence that conflicts of interest are pervasive in the asset management business owned by investment banks. Using data from 1990 to 2008, we compare the alphas of mutual funds, hedge funds, and institutional funds operated by investment banks and non-bank conglomerates. We find that, while no difference exists in performance by fund type, being owned by an investment bank reduces alphas by 46 basis points per year in our baseline model. Making lead loans increases alphas, but the dispersion of fees across portfolios decreases alphas. The economic loss is $4.9 billion per year.

Diseño de un fondo de inversión colectiva basado en derivados energéticos

El propósito de este trabajo de grado es diseñar un fondo de inversión colectiva donde los activos predominantes sean derivados energéticos -- Lo anterior, ajustado al marco normativo expedido por el Ministerio de Hacienda en 2013 -- Para su diseño se estudiará el comportamiento de los derivados energéticos en el principal mercado de futuros: New York Mercantile Exchange y Derivex, que es el mercado de derivados de commodities energéticos en Colombia -- Se recopilarán datos a través de una consulta histórica en diferentes sistemas de información, como Bloomberg y Derivex -- Recopilada y analizada la información en referencia, se determinará la composición del portafolio que se ajuste a las necesidades del mercado colombiano y se desarrollarán pruebas y modelos estadísticos para medir los riesgos financieros -- Finalmente, la investigación y el trabajo de campo se presentan en un informe donde se exponen las características que debe tener un fondo de inversión concentrado en derivados energéticos

Monitoring style drift : evidence from U.S. Equity funds

This thesis examines the stewardship and investment style monitoring by managers and boards of U.S. equity funds. Results indicate that complying with a fund’s declared style, especially in value-growth dimension, remains a challenge for fund managers and boards, and that style-based investors should be aware of the risk of style drift since fund managers and boards do not always monitor the fund’s investment style as stated in the prospectus. Results also show that the quality of fund stewardship, as reflected by fund board quality, corporate culture, manager compensation, regulatory history, and fees are effective in ensuring that fund managers and boards perform their fiduciary obligation by increasing monitoring of the fund investment style.

On the Importance of Mutual Fund Families in Emerging Markets

This study contributes to the mutual fund literature by looking at performance persistence on a fund family level, allowing for individual equity, bond and balanced funds to be included under single family umbrellas. The study is conducted on the emerging Finnish mutual fund market, an environment in which the importance of superior fund family teams is likely to be accentuated. Using both non–parametric and parametric tests we find robust evidence of performance persistence for the fund families. Persistence is particularly strong in the first half of the investigation period, which highlights the importance of fund families at early stages of market development.
