Abstract: The purpose of this paper is to establish an asset pricing model that can explain the common variation in stock return. Five common risk factors are identified, three are stock-market factors (an overall market factor and factor related to firm size and book to market equity) and two are bond-market factors (term and default risk). This paper uses time series regression approach of Black, Jensen and Scholes (1972) to study the average returns on 453 randomly selected stocks listed in Singapore stock exchange (SGX) from the period July 2007 until June 2009. Regression of excess stock returns on the term and default factors, captures very little variation in the returns of stocks. Regression of excess stock returns on the Size and Book-to-Market Equity factors is inadequate in explaining variations in the returns of the stock market. Regression of excess stock returns on the Market Excess Return, Size and Book-to-Market Equity factors produces the strongest R2 among previous two models. Finally, attributed to the insignificance of term, default and size factors, we based our final regression model on two factors only, excess market return and book to market equity, and conclude that these are the only two significant risk factors that contributed to the variation in excess stock market returns between the year 2007 to 2009.
