Morningstar further reports that we tend to give an inordinate amount of attention to our investments themselves: what they are, what their returns have been, how well the company is doing. We seem to forget that the buying and selling of these investments depends strictly on our own behavior and emotional state at the time we buy and sell. If you extrapolate this sentiment to millions of investors, you can begin to see how each investor’s individual attitudes and behaviors may shape and form the markets in which you invest, as well as your own performance within these markets.
