As Warren Buffett once pointed out, investment is not a subject in which the person with the highest IQ will do best. I for one take great comfort in this view. I have always thought that investment is a relatively straightforward subject that is best kept simple.
It constantly amazes me how many people who are successful in their business lives seem to struggle when it comes to investing money. They should analyse why they have been successful in their own fields. Very few will have been technical experts. Most will have had a general interest in the area of the market concerned and would have adopted what many would describe as a common sense approach.
