Shareholders of Gorman-Rupp Co. (GRC) looking to boost their income beyond the stock's 1.2% annualized dividend yield can sell the March 2015 covered call at the $35 strike and collect the premium based on the $1.30 bid, which annualizes to an additional 7.2% rate of return against the current stock price (at Stock Options Channel we call this the YieldBoost), for a total of 8.3% annualized rate in the scenario where the stock is not called away. Any upside above $35 would be lost if the stock rises there and is called away, but GRC shares would have to climb 16.1% from current levels for that to happen, meaning that in the scenario where the stock is called, the shareholder has earned a 20.4% return from this trading level, in addition to any dividends collected before the stock was called.In general, dividend amounts are not always predictable and tend to follow the ups and downs of profitability at each company.
