Wednesday's Late Winners & Losers

Stocks were mixed after the bell Wednesday, awash in various earnings news, and leading the gainers were several tech firms.

Juniper Networks (JNPR Quote) was one of the most actively traded winners after the Sunnyvale, Calif., networking-equipment maker said it earned $116 million, or 20 cents a share, in the second quarter (on a non-GAAP basis). This squares with Street expectations, per Thomson Financial, and represents a 2-cent per-share gain on last year. Shares were up 3.8% to $27.75 in recent after-hours trading.

Florida's Citrix Systems (CTXS Quote), another tech name, jumped 8.6% to $38.35 after second-quarter revenue shot up by 21.4% to $334 million -- $28.8 million over estimates. Skyworks Solutions (SWKS Quote), a semiconductor firm based in Woburn, Mass., added 1.8% on word pro-forma per-share income more than doubled to 11 cents a share in that quarter. Analysts were seeking 9 cents.

The financial sector also served up a winner in Washington Mutual (WM Quote). The Seattle-based bank was 3.3% higher at $43 on a 3-cent per-share earnings beat in the second quarter, making 92 cents a share vs. 79 cents last year. Elsewhere, Cubist Pharmaceuticals (CBST Quote) shares leapt 13.2% to $22.63 after swinging to a profit and handily beating estimates.

But on the flip side was another health-care name, ICU Medical (ICUI Quote). The California-based medical-equipment maker was off 5.6% after its per-share profit plunged to 16 cents a share, or $2.5 million, from 40 cents a share last year. Shares were lately trading at $38.61.

Also hurting after hours was Knoll (KNL Quote), which makes office furniture and textiles, after issuing soft guidance. The Pennsylvania-based company topped second-quarter earnings by a penny a share, but pegged adjusted third-quarter revenue at just $243 million to $253 million. Analysts are calling for $268 million. Third-quarter earnings should also lean to the lower end of the consensus. Shares were down $2.09, or 9.3%, to $20.39.
