I make bold claims in this column. I say that long-term stock returns are predictable. I say that the wild bull market of the late 1990s was the primary cause of the economic crisis. I say that stock prices are determined in the short term primarily by investor emotion rather than by rational responses to economic developments. I call the model of understanding stock investing being put forward Valuation-Informed Indexing and claim that it is rooted in the research of Yale Economics Professor Robert Shiller and in the arguments advanced in his book Irrational Exuberance.
