Even if the Federal Reserve moves gradually on raising interest rates, that doesn't mean the markets will, one famed strategy expert told CNBC.
In his television debut, JPMorgan's Marko Kolanovic, told the "Fast Money" traders what to expect from Wednesday's Federal Reserve meeting into 2016. He said the Fed decision might be like water turning to ice.
"When you gradually decrease the temperature below freezing point, a complex system does not have to respond gradually," Kolanovic said. "You could actually have a big risk-off event if the pace of the hike is too fast."
