For example, a company with a share price of $100 and a dividend of $6 per share has a 6% dividend yield, or 6% return from dividends. The average dividend yield for companies in the S&P 500 is 2-3%. But income investors demand a much higher yield than 2-3%.he income investing strategy is about more than using a stock screener to find the companies with the highest dividend yield. Because these yields are only worth something if they are sustainable, income investors must be sure to analyze their companies carefully, buying only ones that have good fundamentals.
Ladder Strategy. An investment strategy in which one invests in several securities with different maturities. When the first one matures, the yield may or may not be used to buy another security. It is used most often with bonds and certificates of deposit. Laddering protects the investor from interest rate risk by locking in interest rates at once. Suppose one does not use laddering: one may invest $30,000 in a five-year bond with a 4% coupon. When the bond matures, prevailing interest rates may have dropped to 2%, making it impossible to achieve the same profit reinvesting in the same type of bond.
