The investing strategy I am currently Interested in is called dividend investing. That is where you own stock in a company andbit pays you a small share of its profits, usually this is just a few cents per share of stock. Not all companies pay out dividends, but some do. Theoretically, if you own a large variety of a lot of stocks you could be living off the dividends, assuming you are living cheaply.
Yield on cost is the ratio of how much it will pay you, the yield, for the cost of the stock. I found an amazing yield on cost calculator here. You just type in the ticker symbol and it tells you the yield on cost ratio per thr most recent dividend payout information.
Before purchasing any stocks it is wise to learn about the company first, but this can be one great way to figure out how to work this investment strategy. Another way is to figure out what the funds at the large investment houses are buying sticks in and holding those individual stocks. Remember that you should have a broad and diverse investment strategy and not be heavily invested in just one sector like healthcare or oil.
