The amount of annual cash dividends distributed to common shareholders relative to the common stock's market value is termed as the "Dividend yield." This is a financial ratio that signifies how much a company gives back to its shareholders in the form of dividends each year. It's an important data point for investors as it provides insight into a company's dividend profitability.
Please note, while the question prompts a conceptual term, it does not provide specific data or numbers to perform a possible mathematical calculation.
Strictly speaking, the Dividend yield can be calculated as follows:
Dividend yield = (Annual dividends per share/Price per share) * 100
But we can't perform the actual calculation without numerical data.
Hence, the term for the concept asked in the question is the "Dividend yield."
