The markets started on an upbeat note Monday, boosted by some encouraging earnings and signs of an improving economy. The Dow Jones Industrial Average rose 104.21, or 1.19%, to 8,848/15, while the S&P 500 rose 10.75, or 1/14%, to 951.13. The Nasdaq was up 22.68, or 1.2%, to 1,909.29. Joe Terranova said on CNBC's "Fast Money" TV show that the market is going to get a "massive buy order" when the people sitting on the sidelines get into the market. Tim Seymour said the market is performing well because the earnings are coming through and companies are beating on the top line. Steve Grasso said the difference between this earnings season and others is that this earnings season came "out of the blocks strong." He said the return of mutual fund and pension fund money from the sidelines will make a difference in whether the market continues to rally. Pete Najarian noted that investors saw a "global push" on the market from the upgrades of Caterpillar ( CAT) and Peabody Energy ( BTU) that is going to entice people on the sidelines to come in. Melissa Lee, the moderator of the show, wondered whether Goldman Sachs' call of 1060 for the S&P essentially was a market bottom. Terranova stressed that the hand being played out right now is very under-invested as people are cautiously trying not to be too optimistic. Moving on to tech, Seymour said he was concerned that Cisco ( CSCO), Intel ( INTC) and some other names were selling down after running up against some resistance levels with respect to their relative strength indicators.
