Abstract: The emphasizing on the relevance among diverse assets and utilization of the diminishing risk-reducing power of incremental assets’ inclusion, demonstrate enormous efficiencies of diversifications for constructing and managing portfolios. Nevertheless, the degree of efficiency and applicability of modern portfolio are still under question due to the lack of market efficiency and immaturities of emergency economies. The study is primarily designed through the employment of Modern Portfolio Theory with the perception of diversification for the risk deduction and optimization of the returns given risk, implementing regular theoretical structure including Security Market Line, Correlation matrix, and macro analysis, etc. The examination relies on the historical data of blue chip stocks from the Stock Exchange of Thailand with three consecutive years of 2010 to 2012. The resulting performances are further tested by, Sharpe ratio, Treynor ratio, Jensen ratio and information ratio. It shows that the particular portfolio generated from modern portfolio theory approach, provides the superior return than the passive market-index approach does.
