This year, Doug Kass has suffered the unenviable fate of watching the market rise 13 percent while he remained bearish. But on Thursday he told CNBC that the end of the rally will soon be upon us.
"The narrative now is whether the Fed is simply pushing on a string," Kass said, "and many market participants are coming to this 'aha' moment."
Kass, the founder and president of Seabreeze Partners Management, believes that the data have been weak, and will get even weaker.
