Billionaire activist investor Carl Icahn said on Thursday that it is time for investors to tread carefully after the run-up in U.S. stock markets.
"In my mind, it is time to be cautious about the U.S. stock markets," Icahn said in a telephone interview. "While we are having a great year, I am being very selective about the companies I purchase.''
Icahn also said Family Dollar Stores Inc should think about a possible sale to Dollar General Corp.

"The leadership, to say the least, is questionable at Family Dollar and it's been that way for many years,'' Icahn said. "Howard (Levine) might be a nice guy but he is far from the right leader for Family Dollar.''
