“Activist investor Carl Icahn took to Twitter and CNBC Wednesday to issue a stark warning to investors: ‘I think the public is walking into a trap again as they did in 2007,’ Icahn told CNBC. Specifically, the 79-year-old investor warned of a bubble in high-yield debt. The prominent investor joins a chorus of voices pointing at frothiness in the so-called junk-bond market, including DoubleLine Capital founder Jeff Gundlach. In two tweets published on Wednesday, Icahn cautioned against listening to so-called permabulls, saying the 2008 crisis might have been avoided if more investors had warned about the risk of a bubble in 2007, as he is attempting to do now.”
