As you can see the risk of your portfolio is significantly growing (blue line). Your manager is asking you what is going on? Why is the risk growing? What will you reply to him? a. Product A has higher risk than B and since the share of A is significantly growing. This is most probably causing the growth of the risk of all portfolio. From the underlying data, we could calculate exactly how risk of product B behaves. b. Product A has higher risk than B and since the share of A is significantly growing. This is most probably causing the growth of the risk of all portfolio. From the underlying data, we can’t calculate exactly how risk of product B behaves. We can just approximate it. c. There are some important data missing we need more graphs to say anything. d.
