Monday's Small-Cap Winners & Losers

Small stocks generally trailed two of the major indices Monday -- the Dow Jones Industrial Average and the S&P 500 -- and among the biggest losers was China GrenTech (GRRF Quote).

The wireless-products maker posted a first-quarter loss of 23 cents per American depositary share -- a penny wider than what the Street was expecting, according to Thomson Financial. Shares slid 7.8% to $10.60.

Catuity (CTTY Quote) plummeted 25.8% to $1.67 after it reported a loss of $1.5 million, or 64 cents a share, which was 30.6% wider than last year's per-share loss. The Virginia-based gift-card-processing purveyor also reported 12.8% lower revenue at $419,000.

Syntax-Brillian (BRLC Quote) slid another 8.4% to $6.41 one trading day after the high-definition-TV maker announced a $172 million stock offering. The Tempe, Ariz., company filed for the offering today and said it will consist of 25.6 million shares, as well as an underwriters' option for up to 3.8 million more.

On the other hand, Critical Therapeutics (CRTX Quote) was among the day's biggest small-cap winners. The Lexington, Mass., biotech rocketed 61.2% to $2.66 after the Food and Drug Administration approved Perforomist, a treatment for emphysema and chronic bronchitis developed by its co-promotion partner, Dey, an affiliate of Merck KGaA.

Broker First Albany (FACT Quote) announced it will get a $50 million equity investment from private-equity firm MatlinPatterson, and that CEO Peter McNierney will shift to become chief operating officer while the CEO role is assumed by Lee Fensterstock. Shares jumped 15.6% to $1.85.
