Levkovich characterizes slowdown as "soft patch."

In special coverage ahead of today's Federal Open Market Committee decision from Citi's trading floor, Chief U.S. Equity Strategist Tobias Levkovich told CNBC that he was not expecting news that would cause him to make major changes to his outlook for stocks. Despite some troubling macro data, "I think the issues are still in place in terms of credit conditions for it to be just a soft patch," he said.
