Small-cap stocks diverged from the mostly flat broader market Friday and drooped into negative territory, thanks to names like Michigan-based Universal Truckload Services ( UACL), which plummeted 19% to $22 after first-quarter income slid 28.6% year over year to 20 cents a share. Analysts polled by Thomson Financial were looking for 31 cents a share. Gene Logic ( GLGC), which sells services to the pharmaceutical and biotech industry, was also hurting after posting a steep first-quarter loss of 32 cents a share. This narrowed slightly from last year, but was still 25 cents short of expectations. Shares were losing 15.3% to $1.95. Lydall ( LDL) was 13.4% lower at $15.70 after the Manchester, Conn., engineering company said income slipped by a penny a share from last year to 12 cents -- 4 cents shy the sole analyst's target. Beacon Roofing Supply ( BECN), of Peabody, Mass., predicted it will swing to a fiscal second-quarter loss of 14 cents to 16 cents a share against analysts' upside expectations. Shares lately fell 9.4% to $16.41. As for small-cap tech losers, Intervoice ( INTV), Openwave Systems ( OPWV) and Rackable Systems ( RACK) all reported wider-than-expected losses in the quarter ended March 31. Intervoice, which sells converged voice-and-data products, plunged 13% to $6.34. Openwave, an Internet-software developer, sank 9.9% to $7.28, and Rackable, maker of computer-storage systems, slid 9.4% to $11.40. But the tech sector also produced a number of small-cap winners. Utah's Sento ( SNTO), for example, gained 12.1% to $2.23 in far heavier-than-usual trading after saying its right-channeling technology (involving a mix of communications channels) had been chosen to support Amp'd Mobile customer-service operations. MDI ( MDII), of San Antonio, Texas, said the U.S. Navy had placed orders for its One Unified Technology security platform, as well as for an intrusion-detection system. Shares were soaring 19.4% to $1.85.
