The formula to calculate the Stock Yield (SY) is:
\[ SY = \frac{DA \cdot DPY}{SP} \]
Where:
A stock yield is a ratio of the total dividends paid per year over the initial share price of the stock. This term is also often used interchangeably with dividend yield.
Let's assume the following values:
Using the formula to calculate the Stock Yield (SY):
\[ SY = \frac{5 \cdot 4}{100} = 0.2 \]
The Stock Yield (SY) is 0.2 or 20%.
