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) - Get Report

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) - Get Report

, 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

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.

Elsewhere,

Synchronoss Technologies

(SNCR) - Get Report

, maker of transaction-management software, and California-based semiconductor
