According to CBS News, Harry Dent's predictions in his books have never been right. His most accurate prediction was from his 1993 book; he predicted that the stock market would rise substantially, but he was a year early with his prediction.
Harry Dent is a best-selling financial author who claims to have accurately predicted the periods when the U.S. stock market would rise and when it would crash, notes CBS News. He also claims to have predicted the economic recessions in the U.S. and Japan. Dent says that people can learn how to profit from his predictions by reading his books.
Dent published "Great Boom Ahead: Your Comprehensive Guide to Personal and Business Profit in the New Era of Prosperity" in December 1993, according to CBS News. In that book, he predicted that the stock market would rise substantially beginning in 1994. While the stock market only rose by 1 percent in 1994, it rose almost 29 percent each year from 1995 to 1999.
Dent wrote "The Roaring 2000s" in October 1999. He predicted that the stock market would rise substantially during the next 10 years. Instead, the stock market lost about 9 percent during that period, as CBS News explains.
In January 2006, Dent published "The Next Great Bubble Boom: How to Profit from the Greatest Boom in History: 2006-2010." During the boom period that he predicted, the stock market returned about 2.3 percent each year, which is less than the return on safer investments, such as bonds, as CBS News details.
