It is important to note that when thinking about stock yield, is that dividends are determined by the vote of the Board of Directors of a company, and must be voted upon every year and indeed every quarter. Past dividends, studies show are usually indicative of future dividends or stock yield(s), but this is not assured. Companies do not to rattle the boat too much by disturbing the flow of dividends or stock yields to the investors.

Since there is no certainty of stock yield to the investor, when investors think about stock yield, they usually think about it as a current stock yield.

History of Stock Yield

As a general rule, the higher the stock yield or dividend yield, than the more riskier the stock investment becomes. At the same time, the higher the stock yield the more desirable the investment, but again this is a general rule, with many, many exceptions. You can draw some conclusions from a high stock yield. One might be that the stock price itself is underpriced, and due to go up.

Another conclusion is that the company is not doing as well as one might hope and therefore the stock yield is being ready to be cut. It could be that the company is a cash cow, meaning that it is generating large amounts of cash, and this cash in turn is being given back to the investors in the form of a large dividend or stock yield.
