Turning to the other side of the option chain, we highlight one call contract of particular interest for the September expiration, for shareholders of Alcoa, Inc. ( AA) looking to boost their income beyond the stock's 0.9% annualized dividend yield. Selling the covered call at the $13 strike and collecting the premium based on the 88 cents bid, annualizes to an additional 15.8% rate of return against the current stock price (this is what we at Stock Options Channel refer to as the YieldBoost), for a total of 16.8% annualized rate in the scenario where the stock is not called away. Any upside above $13 would be lost if the stock rises there and is called away, but AA shares would have to advance 1.9% from current levels for that to happen, meaning that in the scenario where the stock is called, the shareholder has earned a 8.8% return from this trading level, in addition to any dividends collected before the stock was called.
