Do your civic duty on Election Day and vote, go to church on Sundays, but always bring a cool unemotional detachment to investing on Mondays. That is a favorite theme of mine, one I hammer on in these pages all the time. It is why it is so important to separate your emotions from your investment portfolio. That was the reasoning behind a column I wrote last year questioning whether people should buy an exchange-traded fund based on biblical values. I have no problem with people wanting to feel good about their investments, but I also want them to realize what their choices potentially do to their returns.
