"I've long thought that they would choose to remain at the end of the day," Keon told CNBC's "Squawk Box. " "I think they will choose to remain and that's probably the best way to position portfolios."
Opinion polls taken before Thursday's vote indicated the outcome was too close to forecast, although two polls published late Wednesday suggested a swing toward remain.

"We had thunderstorms and lightning last night and it's a very nervous day in London. Whatever happens, there will be some movement in price. Even though the market has called for, or is pricing for, remain, [it] is still pricing some possibility … of a Brexit," he said.
