Aviza Technology ( AVZA) stock soared nearly 24% in extended trading Thursday after the California-based company more than doubled its sales and swung to a profit for the quarter ended Dec. 29. The maker of semiconductor capital equipment posted earnings of $1.1 million, or 7 cents a share, on revenue of $62.2 million. That compares with a loss of $4.6 million, or $1.25 a share, on $28.9 million in revenue a year ago. Shares were adding $1.06 to $5.50. Secure Computing ( SCUR) said fourth-quarter earnings totaled $5.3 million on a non-GAAP basis, or 7 cents a share, handily beating Street estimates that called for break-even, according to Thomson Financial. The San Jose, Calif., maker of network-security products took in $51.6 million revenue, falling just below the $55.8 million consensus. Last year, earnings were $6.7 million, or 17 cents a share, on sales of $30.2 million. In the current quarter, the company expects to make between $2 million and $3 million on a non-GAAP basis, or 3 cents to 4 cents a share -- at least a penny above the mean target. Shares were up $1.29, or 19.1%, to $8.04. Intuitive Surgical ( ISRG) shares were leaping after the Sunnyvale, Calif., surgical-equipment maker's plunging profits comfortably topped Wall Street expectations.
