J.P. Morgan Asset Management publishes information about financial investments. Overthe past 10 years, the expected return for the S&P 500 was 5.04% with a standard deviation of 19.45% and the expected return over that same period for a core bonds fund was5.78% with a standard deviation of 2.13% (J.P. Morgan asset Management, guide to theMarkets, 1st quarter, 2012). The publication also reported that the correlation betweenthe S&P 500 and core bonds is −.32. You are considering portfolio investments that arecomposed of an S&P 500 index fund and a core bonds fund.a. Using the information provided, determine the covariance between the S&P 500 andcore bonds.b. Construct a portfolio that is 50% invested in an S&P 500 index fund and 50% in a corebonds fund. In percentage terms, what are the expected return and standard deviationfor such a portfolio?c. Construct a portfolio that is 20% invested in an S&P 500 index fund and 80% investedin a core bonds fund. In percentage terms, what are the expected return and standarddeviation for such a portfolio?
Inverse Normal Distribution
The method used for finding the corresponding z-critical value in a normal distribution using the known probability is said to be an inverse normal distribution. The inverse normal distribution is a continuous probability distribution with a family of two parameters.
Mean, Median, Mode
It is a descriptive summary of a data set. It can be defined by using some of the measures. The central tendencies do not provide information regarding individual data from the dataset. However, they give a summary of the data set. The central tendency or measure of central tendency is a central or typical value for a probability distribution.
Z-Scores
A z-score is a unit of measurement used in statistics to describe the position of a raw score in terms of its distance from the mean, measured with reference to standard deviation from the mean. Z-scores are useful in statistics because they allow comparison between two scores that belong to different normal distributions.

a. Using the information provided, determine the
core bonds.
b. Construct a portfolio that is 50% invested in an S&P 500 index fund and 50% in a core
bonds fund. In percentage terms, what are the expected return and standard deviation
for such a portfolio?
c. Construct a portfolio that is 20% invested in an S&P 500 index fund and 80% invested
in a core bonds fund. In percentage terms, what are the expected return and standard
