A fund manager has a well-diversified portfolio that mirrors the
performance of the Hang Seng Index and is worth $1 billion. The
value of the S&P 500 index is 4,000, and the portfolio manager
would like to use a covered call strategy with strike price 5%
above the current level over the next three months. The risk-free
interest rate is 1% per annum. The dividend yield on both the
portfolio and the S&P 500 index is 2%, and the volatility of
the index is 20% per annum.
