Is it wise to invest in a stock with a large Div yield?
There have been many interesting and correct answers but to give a direct answer to your first question, dividend yield is simply dividend over current share price. So, if the share price drops, your dividend yield increases proportionately. Dividend yield is not something one should use as the only source of information of whether a stock is a good/bad buy. It does not show many important factors: the riskiness of the company business, its financial position, profitability, ability to generate cash. Furthermore, dividend yield is just a snapshot of an income gain at a given point in time. It does not mean that this very dividend policy is going to continue in the future (especially not so if the company finances this dividend payments using not its own cash reserves but outside capital by issuing debt securities, which is unsustainable).
