Art Cashin says the market could continue to run higher into the end of the year, but warns that any of three events could put the kibosh on the rally: a European slowdown, a geopolitical flare-up and a continued rise in interest rates.
"The 'Santa rally' traditionally start the week after Thanksgiving, so we'll get a good look at it," Cashin said on Tuesday's episode of "Futures Now."
"The only thing that could throw it off is if the European economies start to stutter. Because the S&P has benefited from the fact that it's not just the U.S.—it's filled with multinationals that have made money in Europe—and I think we're doing a little pause for reflection here, trying to figure out how much the European component will kick in."

More broadly, Cashin said "there's always the risk" that the hazard of a market decline outweighs the reward of further gains. He adds that this could be particularly true if a geopolitical conflict rears its ugly head.
