Risk and Return of the Risky Portfolio

Find the spreadsheet labeled “Optimal Portfolio Weights – 2017 – for students” in the Resources section of our class’ Isidore page.

  1. Construction of the investment opportunities set: In the tab labeled “Risk and Return Info” you will find the holding period returns you calculated during Excel Assignment #1. You will also find arithmetic average returns, standard deviations, variance, covariance and correlation coefficients.


Use this data to construct the investment opportunities set, which is the set of all possible portfolios that can be built with different weights of TSLA and GM. Calculate the standard deviation and expected returns of 100 portfolios with weights of TSLA ranging between 0% and 100% in increments of 1%.


  1. Graph the investment opportunities set in a mean-variance graph. This is, a chart in which standard deviation is recorded in the horizontal axis and expected return is recorded in the vertical axis
