Not a big fan of Harry Dent. He's one of those guys who makes a lot of big predictions and tries to live off the ones he gets right while quietly ignoring the ones he gets wrong. A lot of those guys are good at getting publicity and selling books, but I doubt they could make money trading.

Here's a sample of his predictive abilities (took this from Wikipedia):

"his latest book, The Great Depression Ahead: How to Prosper in the Crash Following the Greatest Boom in History ...." In his 2006 work, Dent predicted, “The Dow hitting 40,000 by the end of the decade, the NASDAQ['s] advancing at least ten times from its October 2001 lows to around 13,500, and potentially as high as 20,000 by 2009 … The Great Boom['s] resurging into its final and strongest stage in 2007, and even more fully in 2008, lasting until late 2009 to early 2010.” None of these predictions turned out to be true. In 2011 and 2012, Dent made new predictions on the state of the Dow Jones Index and the S&P 500 in both the short and long term.[5] Among these was a prediction that the S&P 500 would fall 30-50% inside of 2012. However, the S&P 500 ended the year 2012 up 13.4%
