The typical fund company services 401k plan participants in the same way that Baby Face Nelson serviced banks.

You have to ask yourself, what are the things that matter to you most in your life? If you have to have a latte every day that'snice to have right now, but if you take that latte every day right now, you may wind up eating cat food when you are 70. And you have to decide which is worse.

When it comes to fund managers and market strategists, this year's hero usually turns into next year's zero.

While it is probably a poor idea to own actively managed funds in general, it is truly a terrible idea to own them in taxable accounts... taxes are a drag on performance of up to 4 percentage points each year... many index funds allow your capital gains to grow largely undisturbed until you sell... For the taxable investor, indexing means never having to say you're sorry.

A decade ago, I really did believe that the average investor could do it himself. I was wrong. I've come to the sad conclusion that only a tiny minority, at most one percent, are capable of pulling it off. Heck, if Helen Young Hayes, Robert Sanborn, Julian Robertson, and the nation's largest pension funds can't get it right, what chance does John Q. Investor have?

There are two kinds of investors, be they large or small: those who don't know where the market is headed and those who don't know what they don't know. Then again, there is a third type of investor: the investment professional, who indeed knows he doesn't know, but whose livelihood depends upon appearing to know.

Do the math. Expect catastrophes. Whatever happens, stay the course.
