What would the valuation level be? Fair value! The logical thing to do is to respond to overvaluation by selling stocks since the long-term value proposition has worsened (bringing prices back down to fair value) and to respond to undervaluation by buying stocks since the long-term value proposition has improved (bringing prices back up to fair value).<br /><br />Markets are self-regulating so long as investors are encouraged to take valuations into consideration when setting their stock allocations. All overvaluation and undervaluation is caused by promotion of the Passive Investing concept, the idea that it is not necessary to change one's stock allocation in response to price changes.<br /><br />The P/E10 level (the price of an index over the average of the last 10 years of earnings) tells you how emotional investors are at any given time. In January 2000, the P/E10 was 44, three times the fair value P/E10 of 14. That told us that that was the most emotional market we have ever seen in U.S. history and the most dangerous market for those looking for a place to invest their retirement money.<br /><br />RobRob Bennetthttp://arichlife.passionsaving.comnoreply@blogger.com
