Looking at the Long Term

The "long run" isn't everything, but it's something, which is to say it's relevant. Studying it, then, is productive. It shouldn't dominate decisions for designing and managing asset allocation, but it's a great place to start.

The long run is everywhere when perusing the latest edition of Ibbotson SBBI 2009 Classic Yearbook.
