The financial sector is up 30 percent since January of last year. J.P. Morgan and Goldman, as two major pillars of the sector will be most scrutinized. "I think people are going to look long and hard at these businesses and what interest income looks like," said Steve Massocca of Wedbush Securities of J.P. Morgan. "They're going to want to get into the weeds and see how these businesses are doing."

Massocca and others say the market is at an important pivot point. He said poor earnings could drive the market into correction, but it's too early in the reporting season to tell which way things are going.
The S&P 500 closed 1 point higher at 1472, and the Dow was up 27 at 13,534 Tuesday.
"We've been hanging around the September high for four days in a row so something is going to break one way or the other," he said. "I think if we break through it, we could run back to the old 2007 high. Conversely, if we fall through it, we'll go to (S&P) 1400. We're at an important juncture."
"Estimates have really been whittled down. If you look at where estimates were in October and November, the estimates were much lower than they are today. I would have said a month ago, it's going to be a disappointing earnings season, but I don't know because they've been revised down so much," Massocca said.

As the Dow edged up slightly Tuesday, the Dow Transports rose 0.7 percent to a new high. "It's significant. It's going to get all the Dow theorists back out again, but I think you want to wait and see if you get follow through with the industrials," said Art Cashin, director of floor trading at UBS.
As the theory goes, the industrials must confirm the move in the transports for the market to move higher. Massocca said the move in the broader indexes, like the S&P 500, are more important.
"In the next two weeks, earnings are going to be the really big news. Once that's passed, all eyes will be focused on that great sequel – fiscal cliff two," he said, of the pending debt ceiling and spending debate.
