Final answer:
To find the percentage of the return from fund XYZ that is due to the S&P, we need to calculate the beta coefficient and multiply it by the correlation coefficient. The correct answer is Option B. 81%.
Step-by-step explanation:
To find the percentage of the return from fund XYZ that is due to the S&P, we need to calculate the beta coefficient. The formula to calculate the beta coefficient is:
Beta = Covariance(stock XYZ, S&P) / Variance(S&P)
Then, we multiply the beta coefficient by the correlation coefficient to find the percent of the return due to the S&P. With a beta of 1.4 and a correlation of 0.90, the percent of the return from fund XYZ that is due to the S&P is 81%. Therefore, the correct answer is Option B. 81%.
