Every dividend investor should be focusing not only on dividend income, but also evaluating the safety of their principal. If the high-yielding stock is paying a 10% current yield, but most of it is a return of capital, then chances are that the dividend payment will not be maintained in the future as the company’s capital base shrinks. Furthermore if a stock used to yield 3% but due to a decrease in its stock price is yielding 12%, the market might be sending a message that the current dividend payment is in danger of a cut. Financial companies like Bank of America (BAC) and Citigroup (C) in 2008 are a prime example of this scenario, as their current yields rose to 8%-10% because their stocks fell sharply in response to the softening of the general economy. Investors who purchased these stocks were hit on two fronts – the share prices dipped lower and the dividends were cut, which decreased yields on cost significantly. In other words if you are chasing a 30% dividend yield, then make sure that you don’t lose a lot in capital gains in the process.
