In 2000, based on his forecast that economic growth would continue throughout the 2000s, Dent predicted that the DOW would reach 40,000, a prediction which was repeated in his 2004 book. In his book, he also predicted the NASDAQ would reach 13,000 - 20,000. In late 2006 he revised his forecasts to much lower levels, estimating the Dow would reach 16,000 - 18,000 and the NASDAQ 3,000 - 4,000. In January 2006, he predicted that the DOW would reach 14,000 - 15,000 by the end of the year. It ended 2006 at 12,463, 11% below the lower end of his prediction. It ended 2007 at 13,264, again significantly lower than Dent's revised prediction of 15,000 by early 2008. Since then, the Dow crossed 14,000 in late 2007 before retreating.
His 2011 book goes on to suggest consumer spending will begin to plummet in 2012 with the Dow bottoming out somewhere between 3,000 and 5,600 in 2014. After hitting bottom, stocks will experience a mini-rally in 2015-2017 before falling into a final bottom during the 2019-2023 period, when the 45-50 age group troughs because the U.S. birth rate reached its own low in 1973.
