1 Find the risk of a protfolio of the following proportions: w1=0.3,w=0.5,w3=0.2 2 what is the risk of investing in only Petra stocks. 3 Use excel solver to find the best proportions to invest an amount of $1000,000, that will minimize the risk. 4 if you want to invest 50% in Intellegenct systems, what are the best fractions of the remaining stocks that will minimize the risk. 5 For quation number 5, sketch the resulting risk in the Y-axis, while w1 in the X-axis with inrements of w1: 0:0.05:0.5 1 Find the risk of a protfolio of the following proportions: w1=0.3,w=0.5,w3=0.2 2 what is the risk of investing in only Petra stocks. 3 Use excel solver to find the best proportions to invest an amount of $1000,000, that will minimize the risk. 4 if you want to invest 50% in Intellegenct systems, what are the best fractions of the remaining stocks that will minimize the risk. 5 For quation number 5, sketch the resulting risk in the Y-axis, while w1 in the X-axis with inrements of w1: 0:0.05:0.5
