Shareholders of Sterling Bancorp (STL) looking to boost their income beyond the stock's 2.4% annualized dividend yield can sell the May covered call at the $12.50 strike and collect the premium based on the 5 cents bid, which annualizes to an additional 31.9% rate of return against the current stock price (at Stock Options Channel we call this the YieldBoost), for a total of 34.4% annualized rate in the scenario where the stock is not called away. Any upside above $12.50 would be lost if the stock rises there and is called away, but STL shares would have to climb 9.4% from current levels for that to happen, meaning that in the scenario where the stock is called, the shareholder has earned a 9.8% 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.
