NEW YORK (MktNews) - U.S. shares showed resilience and rebounded Tuesday on dip buying, quieting nervous stomachs following Monday's dramatic slide. The Nasdaq composite rose 91.27, or 4.7 percent, to 2014.65 to end back above 2,000. On Monday, the index fell more than 6 percent. The Dow Industrials, down more than 400 points on Monday, rose 81.58 to 10289.83, while the S&P 500 rose 17.33 to 1197.49. Volumes were extremely heavy. Dip buying helped most technology blue chips, including networking leader Cisco up 2 5/16 at 21 1/8 [CSCO], chip leader Intel up 1 41/64 at 29 25/64 [INTC] and fiber optic leader Corning up 1.07 at 24.50 [GLW]. Tuesdays bounce aside, dealers said worries over the slowdown in capital equipment investment will continue to dog the sector. Retail sales were much weaker than expected in February, falling 0.2 percent and building back hopes for a 50 basis point rate cut at the Federal Reserve's March 20 policy meeting. Dealers said aggressive rate cuts would help the market more than weak economic data is hurting it. Motorola, up 0.32 at 15.32 [MOT], said it will cut more than 7,000 jobs, while Delta Air fell 1.64 to 41.46 [DAL] after saying it will post a wider loss than expected, news which took the whole airline sector down with it. General Electric, up 2.84 at 42.44 [GE], confirmed estimates. Tyco International, down 4.33 at 46.37 [TYC], said it will acquire CIT Group, up 8.20 at 30.95 [CIT] for more than $9 billion in stock.
