What is the biggest mistake you see in portfolios you review?

Most investment portfolios are much too complicated. It is not unusual for an investor to own more than a dozen mutual funds that were accumulated over the years and then forgotten. Also, most investors have their money disbursed over several mutual fund companies and brokers. In these situations, most of the time that is put into investing is spent simply collecting and analyzing the paperwork to find out how the portfolio is invested. The real work of deciding how the portfolio should be invested is given less time. Often, the time involved in collecting the information then shifting funds among different mutual fund companies and brokers is overwhelming. Procrastination sets in and nothing is done. I recommend that investors simplify their financial lives, as I described earlier. Invest in mutual funds through a discount broker or limit your investments to one or two mutual fund families.
