Small stocks mirrored the rest of the rising market Wednesday as several names issued positive earnings reports. Among these was Industrial Services of America ( IDSA), which surged 47.3% to $13.23 after the Louisville, Ky., management-services firm made a dime a share more than last year at 22 cents a share, or $793,000. RC2 ( RCRC), a toymaker based in Oak Brook, Ill., bested per-share Wall Street estimates from Thomson Financial by 6 cents, with first-quarter earnings of 37 cents a share. Shares leapt 9% to $44.05. Additionally, business-services firm Portfolio Recovery Associates ( PRAA), of Norfolk, Va., jumped 14.3% to $55.78 after reporting a healthy year-over-year rise in earnings to $12.9 million, or 80 cents a share -- 3 cents past estimates -- and tableware-products maker Libbey ( LBY) swung to a loss of 12 cents a share but still smashed expectations. Shares of the Toledo, Ohio, company rose $1.43, or 8.2%, to $18.79. BioDelivery Sciences International ( BDSI), meanwhile, rocketed more than 30% in extremely heavy trading volume after the Morrisville, N.C., biotech's Bema Fentanyl treatment for breakthrough pain (severe bouts of pain that "break through" regular medication) yielded statistically significant results in late-phase testing on cancer patients. The study achieved its primary efficacy endpoint. Shares closed up $1.41 at $6.05. Elsewhere, sporting-goods maker K2 ( KTO), based in Carlsbad, Calif., agreed to sell itself to Jarden ( JAH) for $15.50 a share in cash and stock -- or $1.2 million including debt assumption -- in a deal that will likely close early in the third quarter. K2 shares lept $2.52, or 20%, to $15.10; Jarden fell 3.5% to $41.58.
Palomar Medical Technologies ( PMTI), maker of laser-based systems for medical and cosmetic treatments, jumped 5.3% to finish at $40.12 after Lazard upgraded the Burlington, Mass., company to buy from hold. Silverstar ( SSTR) soared 26.7% to $1.85 after the Florida-based entertainment-software developer predicted a near tripling of its fiscal third-quarter sales from last year to range between $4.3 million and $4.5 million. On the same token, however, small-cap jeweler Charles & Colvard ( CTHR) plunged 25.7% to $5.01 after widely missing first-quarter estimates. The Morrisville, N.C., company earned only a quarter of what it did last year -- 2 cents a share -- while analysts had sought 9 cents. Business-services firm Rewards Network ( IRN) tumbled 21% to $4.37 after swinging to a 7-cent per-share loss in the first quarter. Wall Street was seeking a penny in per-share profit. Taylor Capital Group ( TAYC), a bank based in Rosemont, Ill., slid 13.7% at $31.70 after a large loan-loss provision pushed first-quarter earnings down 39.9% year over year to $5.3 million, or 48 cents a share. Finally, several small-cap tech stocks were hit with downgrades. Silicon Storage Technology ( SSTI), of Sunnyvale, Calif., slumped 12.7% to $4.26 after WR Hambrecht cut the chipmaker to sell from hold. Fellow California-based semiconductors Leadis Technology ( LDIS) and Actel ( ACTL), were each lowered to hold from buy, respectively by Needham & Co. and AG Edwards. Leadis shares lost 10.7% to $3.58; Actel slid 9% to $15.93. As for broad trackers, the Russell 2000 and S&P SmallCap 600 indices each closed up around 0.7%.
