It's no secret that the presidential election has been driving investor anxiety.
The key, according to Fidelity's John Sweeney, is to maintain a long-term outlook and faith the market will recover, whatever happens.
"At this point … we're trying to convince people to stay the course," Sweeney told CNBC's "Squawk on the Street" on Tuesday. "If you've got a plan [and] you like it, stay with it."
It is not wise to totally discount near-term market moves, said Sweeney, executive vice president of Fidelity's Retirement and Investing Strategies, but realistically, the election is not a driving market factor like earnings growth and interest rates.
"Have a long-term perspective. Don't be worried about the short-term volatility in the market. You should expect some, and you're going to see it, but really take a longer-term focus," the strategist said.
As for the immediate effects, Willem Buiter, chief economist at Citi, said if Hillary Clinton wins, the stock market would lift a bit, the dollar would fall a bit, rates and yields would inch higher, but there would not be any substantial volatility.
"The immediate effect of a Clinton presidency, which is, I think, priced in, more or less, would be minor financial market reaction," Buiter said Tuesday in an interview with Sweeney.
If Donald Trump wins, on the other hand, Buiter said investors could see "a sharp [appreciation] of the dollar, stock market down, yield curve down and a slowdown because [of] the fear of trade wars and adverse labor supply shock and immigration policies."
