TI (TXN) gave up 44 cents a share, or 1.6%, to fall to $26.73 even though the communications chipmaker posted upbeat earnings results late Monday. Some analysts expressed concern about the chip market's ability to maintain its momentum through the rest of the year.

 
 

Broadcom (BRCM) shares gave up 90 cents, or 2.5%, to fall to $26.76 ahead of the chipmaker's quarterly results, due after the market close.

Nearly every major tech stock was in the red. IBM (IBM) shares gave up 67 cents to slip to $130.06 even after the company said its board of directors approved hiking IBM's quarterly dividend by 18% to 65 cents a share and buying back $8 billion in shares.
