Some people are under the impression that the more they adjust their portfolios by quickly buying, selling and testing out complicated investment vehicles, they will have a better chance of success. This is the worst thing to do. Inaction will lead to success before rushed and emotional responses do. It is difficult to just sit back and occasionally check one’s investments (once every two weeks for example), but it is the best way to go about doing it. After a while one will forget and thus check their portfolio less.
