Compute the daily returns for Ford, GM, and Tesla from August 2018 through August 2022 using the S&P database. After having computed the daily returns, calculate the following:

1a. Average return for Ford.

1b. Return standard deviation for Ford.

2a. Calculate the covariance matrix for the return series, and figure out the following values:

i. Covariance between Ford and GM

ii. Covariance between Ford and Tesla

iii. Covariance between GM and Tesla

2b. Calculate the correlation matrix for the return series, and figure out the following values:

i. Correlation between FORD and GM

ii. Correlation between Ford and Tesla

iii. Correlation between GM and Tesla

3. What insights do you gain from the correlations from 2(b)
