Portfolio return and standard deviation Jamie Wong is thinking of building an investment portfolio containing two exchange traded funds (ETFs). Jamie plans to invest $2,500 in Vanguard S&P 500 ETF (VOO) and $7,500 in Invesco QQQ Trust (QQQ). Jamie has decided to analyze some historical returns to get a sense for her portfolio's possible future risk and return. Six years of historical annual returns for each ETF are shown in the following table: a. Calculate the portfolio return, rp, for each of the 6 years assuming that 25% is invested in VOO and 75% is invested in QQQ. b. Calculate the average annual return for each ETF and the portfolio over the six-year period. c. Calculate the standard deviation of annual returns for each ETF and the portfolio. How does the portfolio standard deviation compare to the standard deviations of the individual ETFs? d. Calculate the correlation coefficient for the two ETFS. How would you characterize the correlation of returns of the two ETFs? e. Discuss any likely benefits of diversification achieved by Jamie through creation of the portfolio. a. The portfolio return for year 2014 is %. (Round to two decimal places.) The portfolio return for year 2015 is %. (Round to two decimal places.) The portfolio return for year 2016 is %. (Round to two decimal places.) The portfolio return for year 2017 is %. (Round to two decimal places.) The portfolio return for year 2018 is %. (Round to two decimal places.) The portfolio return for year 2019 is %. (Round to two decimal places.) b. The average return of VOO over the 6-year period is %. (Round to two decimal places.) SC SC SC
