first asset has an annual expected return of 12 percent and an annual volatility of 15 percent. The
firm has a long position of $43 million in that asset. The second asset has an annual expected
return of 18 percent and an annual volatility of 27 percent. Your firm has a long position of $100
million in the second asset. The third asset has an annual expected return of 15% and the
volatility of 20%. The firm has a short position of $50 million in that asset. The correlations
between returns on these assets are given in the table below:
