Speizer said the main move came right after the exit polls, and even as the results rolled in, markets had not moved much.
"It looks like markets priced in a hung parliament in the first minute," he said.
The biggest problem for the UK is that it weakens their position on the eve of the Brexit talks, Speizer said.
"If you have a strong party with a big majority they would have the backing of the people to negotiate hard and demand. With a weak majority or no majority at all the government's not in a great position to be bold about anything," he said.
The end result might be a weaker UK economy.
Looking ahead, Speizer said markets would now shift their focus to next week's Federal Reserve meeting as well as domestic data, including the balance of payments and gross domestic product.
