father of “Modern Portfolio theory”‚ developed the mean-variance analysis‚ which focuses on creating portfolios of assets that minimizes the variance of returns i.e. risk‚ given a level of desired return‚ or maximizes the returns given a level of risk tolerance. This theory aids the process of portfolio construction by providing a quantitative take on it. It integrates the field of quantitative analysis with portfolio management. Mean variance analysis has found wide applications both inside and outside

case study‚ we conclude that we need to do a variance analysis to better understand the plant performance compared to the previous year. The main problem in related to this case is about the falling in revenues‚ the performance of coal-plant‚ the price of coal and the quality of coal. All of this problem will be answered in the next sections in the qualitative analysis of Luotang Power.
