5. You wish to implement the Markowitz optimization for a portfolio containing 42 risky assets. To do so, you will need to estimate three (3) different types of inputs. Please, name each of these input types (be terse and specific - do not describe them, just name them). Precisely how many estimates will you need for each input type (show how you have arrived at these results)? Suppose you also wanted to find the optimal risky portfolio. What additional input will you need to accomplish it? Be specific. 5. You wish to implement the Markowitz optimization for a portfolio containing 42 risky assets.
