Cashin: Why ‘I hear Santa’s sleigh bells ringing’

Art Cashin: Market activity is all relative

The stock market rally should roll into January and persuade even the most bearish investors to bet on equities, UBS' Art Cashin told CNBC on Monday.

"You're seeing some people who are still concerned with the market, but it's a time to just hold your nose and buy them," Cashin said on "Squawk on the Street." "Because you're not in the business of collecting money. You're in the business of managing money."

Cashin said once the broke through the 1,815 mark, the market got out a "rectangular pattern" and gained momentum.

"I hear Santa's sleigh bells still ringing." Cashin said. "I think we're going to make it."

The "Santa Claus" rally should continue into next month, Cashin said, but not all the way through January. He advised investors to watch 10-year Treasurys, warning that they would attract attention from stock traders once yields surpass 2.95 percent.
