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.
When the weather outside is frightful, natural gas bulls are delighted. And as new forecasts predicted more cold weather ahead, natural gas traded up to six-week high.
"It's been much colder this year, and as long as the weather pattern calls for colder temps, I will not be shorting this market," said Anthony Grisanti of GRZ Energy. "Instead, I will be looking for dips to buy."
Because people use natural gas for heating in the winter and cooling in the summer, the market is extremely beholden to weather forecasts.
"What you will see is that nat gas prices will tend to spike in extreme weather of either variety—hot or cold," said Michael Khouw, managing director at DASH Financial and a former trader of natural gas futures and options. "When it gets extremely cold, you expect natural gas demand to increase."
Weather is "extremely important" to natural gas, said Stephen Schork, editor of the Schork Report. "If the weather turns, it's going to have a significant impact on the cash market in the next day, and will certainly spill over to the futures as well."
And as anyone who has tried to plan a picnic three weeks in advance knows, acting on short-term forecasts makes a lot more sense than listening to longer-term prognostications.
"A one-week forecast is reliable, two weeks is a stretch, and anything above that is tantamount to rolling a die," Schork said.
In fact, so great is the need for short-term forecasts that "all the people who are trading nat gas significantly have private meteorologists," Schork told CNBC.com. That gives them "much more timely information, because the government only updates forecasts once or twice a day."
With December gold options expiring Monday, the market will likely remain in check. But it is still important to watch the U.S. dollar for cues.
December gold futures traded to a low of $1,225.70 in the Sunday overnight session, the metal's lowest level since July 8. Already in a bear market, gold is being led lower by a stronger dollar and by a decrease in global risk premium due to a deal the Iran nuclear deal.

The expiration of the December contract is traditionally the biggest of the year. After a quiet day on Friday in which gold remained in a $10 range below resistance at $1,251 and above $1,240, the stronger dollar sparked selling ahead of expiration.
I'm betting that the market will close higher on New Year's, and here's why.
First of all, for all the fretting about how stocks may have become over-extended, the market's fantastic uptrend is still intact. This rally has been a three-year story, and the story doesn't seem to be over just yet.

In addition, there's a strong seasonal wind at traders' sails in December. Over the past 31 years, if you bought the March e-mini S&P contract on Dec. 1 and sold it on Jan. 17, you would have had 26 winners and five losers, for a conversion rate of 84 percent.
The 10-year Treasury yield hit 2.84 percent on Thursday, the highest level in two months. And MacNeil Curry, the head of global technical analysis at Bank of America Merrill Lynch, warns that if yields continue to rise, it will be a very rocky ride for markets.
"If we take out 3 percent, we'll probably get a move up to about the 3.17, 3.30 area," Curry said. "And if we do it with some momentum, then it's going to cause quite a bit of panic."
If yields rise even higher, then more than panic will result.
"Where things would be truly unhinged, you'd need to see a break of, say, 3.6, 4 percent," Curry said on Thursday's "Futures Now." "If that were to transpire, you want to talk about volatility? It's going to be a different ballgame."
People are more interested in the concept of a "stock bubble" than they've been at any time since the housing bubble collapsed. But ironically, that very concern could be what prevents another bubble from forming anytime soon.
According to Google Trends, worldwide search interest in the term "stock bubble" is higher in November 2013 than in any month since October 2008. The rise in interest is even more pronounced in the United States, where in data going back to 2004, the volume of searches for the term is the highest it's ever been (with the exception of the bubble-period around November 2007.)
Paradoxically, many market participants say this should actually calm those who fret that equities are currently in a bubble.
"That means, conclusively, that there is no stock bubble," Jim Iuorio of TJM Institutional Services told CNBC.com. "It means that people aren't caught up in the hysteria of being deluded that there is no bubble, which is the only way that a bubble can exist."
Mark Dow, a former hedge fund manager who writes at the Behavioral Macro Blog, diagnoses investors with a bad case of "disaster myopia."
"If you went through an earthquake, or were mugged, or whatever traumatic event it might be, you overestimate the probability of that event occurring again," Dow said. "It's because we just went through a bubble that everyone's looking for them. Generals always fight the last war, and firemen fight the last fire."
Dow similarly believes that the tremendous deal of concern about a bubble will "probably prevent it," at least for a little while.
"It's never obvious, by definition, or you wouldn't get the bubble," he said.
