"In order for us to keep going, tech has to join. So far, so good with IBM and Google, and now we have to see what happens with Apple," said Redler. "We can take out the old highs in the S&P, but it doesn't have to happen in the first half of the year. It can happen in the second half."
Worth, who is negative on the market now, said a case in point could be made by looking at the S&P 100 last week.
"The best single performer was Dell, and the worst was Apple. One is basically a dinosaur selling buggy whips," he said of PC maker Dell. But Apple is one of the most valuable enterprises in the world, and yet its stock has suffered a near 30-percent decline from its high on growth and margin fears. Dell has moved higher on leveraged buyout talk. (Read More:
'My Bet Is Up in Apple': Najarian
So far in January, the stock market is up more than 4.5 percent. About 20 percent of the S&P 500 companies had reported earnings by Wednesday, with 68 percent beating estimates, according to Thomson Reuters. Now the earnings wave has turned to tech, and traders say this could be make or break time for the rally which started in November. Microsoft also reports this week, after Thursday's closing bell.
"If Apple and Amazon put up big numbers and go up, this market is going higher," said Worth. But Worth said if there's a big miss in tech land and stocks get hit, "it wouldn't be casual, it would be violent."
However, Redler says that even if Apple misses, the market is used to moving ahead without it, and it may continue to do so.
"I think the market is psychologically prepared to continue without Apple, and if Apple gets involved, it could give it a little bit of an adrenalin shot," said Redler.
The positive reports from Google and IBM triggered a sharp jump in stock futures after Tuesday's close. Google reported earnings per share of $10.59, and the stock jumped four percent.
That was a far cry from last quarter when Google missed its estimate. Google was expected to report fourth-quarter profits of $10.49 per share on revenues of $12.3 billion, according to Thomson Reuters.
IBM stock also moved sharply higher after both profits and revenues beat estimates. The company reported $5.39 per share, compared to estimates of $5.25.earnings and year ago profits of $4.71 per share.
"Google and IBM have both been lagging the tape over the course of the last month," said Redler. "As indices made new highs, there's been concern about Google and IBM, and their lack of participation. I think the market did well going higher without them, so it will be interesting to see what happens if their gap up holds."
