We observe the market capitalization of 5 stocks:

a. Suppose we want to form an equal-weighted portfolio using the above 5 stocks on 15/02/2021, what is the portfolio weight on Stock A?

b. Suppose we want to form a value-weighted portfolio using the above 5 stocks on 31/03/2021, what is the portfolio weight on Stock B?

c. Suppose we want to form a size strategy with quintile portfolios (1 stock per group) using the above 5 stocks on 30/04/2021, which stock should be included in the long-short portfolio?

Which stock should we long?
Which stock should we short?

d. Using the portfolio formed in part (c), compute the one month holding period return for the size strategy.
