Example: Option Strategies
You construct a covered call portfolio by selling one call contract of ABC Inc's stock with a strike price of $40 and buying 100 shares of ABC Inc's stock when they were trading at $42. The call option premium was $2.50. What is the profit in this portfolio if the stock price at expiration is $50?
Practice: Option Strategies

A) What are the break-even points of this portfolio?
