if your portfolio looks like the Yale Endowment's, then you're likely to find yourself chairless when the music stops. Diversifying is easy; doing so early is difficult.The solution? Boring old asset allocation and staying in the market for the long haul. There a really is no Santa Claus, and no tooth fairy, unless you're the next John Templeton and have the courage to get in ahead of the crowd. (And even then, there's no guarantee that you're not the next Bill Miller instead)
The book repeats stuff you probably already know as an investing adult, but the stories inside are worth a quick read and the book is cheap. Recommended.
