Note that dividend yield is calculated using annual dividends per share, regardless of if the dividend is paid quarterly, monthly, or on any other schedule.
For example, if a dividend pays 5.00$ per quarter and the stock price is $100.00, the dividend yield is 20%. This is because the dividend pays $20.00 per year.
It is also important to note that a high dividend yield can be a sign of falling stock prices. Since dividend yield uses the current share price in the denominator, a sharp drop in price automatically raises the yield, even if the money paid hasn’t changed. This can reflect potential market concerns about a company’s financial future
