Rational Expectations is a clean sheet of paper in the wonky world of quantitatively based asset allocation aimed at small investors. Continuing the theme of the Investing for Adults series, this full-length finance title is not for beginners, but rather assumes a fair degree of quantitative ability and finance knowledge. If you think you can time the market or pick stocks and mutual fund managers, or even if you think that you can formulate an optimally efficient mean-variance asset allocation with a black box, then learn some basic finance and come back in a few years. On the other hand, if you know your way around risk premiums and standard deviations and know who Irving Fisher and Benjamin Graham were, and if you want to sharpen your asset class skills, you've come to the right place.
