This project is based on the making efficient portfolio by using a Markovitz Model. we have select the security from the nifty 50. In Nifty 50 Security we have find the Beta of all security. Beta shows the risk presence in security. On the basis of BETA value in which we have taken four securities two is from higher beta value and two is from lower beta value. By making a combination of two securities which is from higher beta value and another two from lower beta value. Than we calculate correlation of coefficient, portfolio return and portfolio standard deviation by giving equally weight of both securities. We prepare questionnaire for to knows the risk level capacity of investors. By making an efficient portfolio we compare portfolio return to a market return which shows that performing better than market return.
