One’s I would recommend are Gorilla Trades, Investment House and Virtue of Selfish Investing.
Harry Dent talks a really good game. I think he has been right. I know he was right once. Heck, a stopped clock is right over 700 times a year, on average.
Harry predicts lots and lots of stuff. And he couches much of it in vagueness and vagaries. He can be right on the money, but 12 months too early or 14 months too late.
Frankly, he does an admirable job of spinning a tale. But I would not risk more than $1,000 on what he advises.
The above is all IMO; past performance is not a guarantee of future results. Your mileage may vary.
