Intel ( INTC) was the most prominent among numerous after-hours losers Tuesday after the chipmaker's earnings weren't up to snuff .
The Santa Clara, Calif., company said it made $2.27 billion, or 38 cents a share, on revenue of $10.71 billion. Year over year, income soared 51.3% and sales climbed 10.5%, but analysts were expecting it to make 40 cents a share on revenue of $10.84 billion, according to Thomson Financial. Shares were falling $2.89, or 12.7%, to $19.80. A number of other big tech names were falling in concert, among them software maker Microsoft ( MSFT), network-equipment maker Cisco Systems ( CSCO), and computer makers Apple ( AAPL) and Dell ( DELL). Shares of each were lately down 3.1% or more. Meanwhile, sportswear retailer Quiksilver ( ZQK) saw some mixed trading after dampening its fiscal first-quarter outlook to a loss of between 8 cents and 12 cents a share. That's down from the "small" loss projection that the Huntington Beach, Calif., company issued last month. The company blamed difficult broad retail trends, as well as lower-than-expected reorders for wintersports equipment. Shares were off 12.5% to $6.50 in very light extended trading. And Theravance ( THRX), a Californian biopharma company, set plans to offer $150 million in convertible subordinated bonds, along with an underwriters' option for another $22.5 million worth for covering any overallotments. Proceeds are slated for general corporate purposes. Shares were down 7.7% in thin volume. On the other hand, Linear Technology ( LLTC) stock was adding 1.8% after the Milpitas, Calif., chipmaker reported its per-share income leapt 20.6% to 41 cents a share -- flush with Wall Street expectations -- thanks to sharply reduced shares outstanding. The company inked a $3 billion accelerated stock-repurchase agreement in April 2007. Total income sank 10.7% year over year to $93.8 million, though revenue gained 7.8% on last year to $288.7 million. Shares tacked on 50 cents to $28.30.
