An investor believes that the Cisco stock price is going to increase in the following 12 months from the current stock price of $200. Call options on Cisco stock expiring in 12 months have a strike price of $224 and sell at a premium of $20 each. The investor has $10,000 to invest, and is considering 3 alternatives:
