Winstek Semiconductor Co 5-Year Yield-on-Cost % Calculation
Dividend Yield % and dividend growth of a stock is an important factor for income investors. But if company A raises its dividend constantly faster than company B, company A's future dividend yield might be much higher than Company B's even if their yields are the same now and their stock prices do not change.
Yield on Cost assumes that you buy and the stock today, and hold it for 5 years. If the company raises it dividends at the same rate as it did over the past 5 years, the dividends investors receive annually in 5 years relative to the stock price today.
