Abstract

Resumen: En la literatura no existe un consenso sobre la relación entre riesgo y rendimientos. Específicamente el riesgo idiosincrático tiene efectos ambiguos sobre los rendimientos considerando diferentes mercados y periodos de tiempo. Este trabajo tiene como objetivo analizar a relación entre riesgo idiosincrático y retornos esperados del mercado accionario colombiano en el periodo de 2009 a 2014. Se adopta la metodología de Fu (2009) usando el modelo de Tres Factores de Fama y French y se estiman las volatilidades condicionales con un modelo EGARCH. Los resultados muestran que el riesgo idiosincrático no tiene efectos significativos sobre los retornos esperados. En conclusión, los inversionistas bajo diversificación no son compensados por el mercado al asumir el riesgo idiosincrático. Así, dadas las posibilidades de diversificación en el mercado accionario colombiano, sólo el riesgo sistemático recibe compensación en función de un mayor rendimiento esperado. Abstract : In the literature there is no consensus on the relationship between risk and returns. Specifically idiosyncratic risk has ambiguous effects on financial performance considering different markets and periods of time. This work aims to analyze a link between idiosyncratic risk and expected returns of the Colombian stock market in the period 2009 to 2014. We adopted the methodology from Fu (2009) using the three-factor model of Fama and French and then, we estimated conditional volatilities with EGARCH model. The results show that the idiosyncratic risk has no significant effect on the expected returns. In conclusion, low diversification Investors not is compensated for the market to take the idiosyncratic risk. Given the possibilities of diversification in the market, only systematic risk is compensated via a higher expected return.
