Wednesday's Small-Cap Winners & Losers

Small stocks vaulted higher than the broader market on Wednesday, largely on positive earnings from names such as TTM Technologies (TTMI Quote).

The Santa Ana, Calif., maker of printed circuit boards soared more than 29% to $11.85 after reporting that first-quarter profits totaled $8.5 million, or 20 cents a share -- 15 cents higher per share than Wall Street's consensus, according to Thomson Financial.

Joining TTM in the green zone were fellow tech stocks Voxware (VOXW Quote), a business-software firm, and Mountain View, Calif., semiconductor company Cavium Networks (CAVM Quote).

New Jersey-based Voxware tripled its value to $6.83 after saying it swung to a first-quarter profit of $685,000, or a dime a share, from a 34-cent per-share loss last year. Sales nearly doubled to $3.6 million. Cavium, meanwhile, vaulted 24.2% to $16.76 following its initial public offering of 6.75 million shares, plus an underwriter's option for about another million in order to cover any overallotments.

Buffalo Wild Wings (BWLD Quote), a Minneapolis-based restaurant chain, likewise handily beat Wall Street expectations with mounting first-quarter profits of $5.5 million, or 63 cents a share. Its stock jumped 14.4% to $74.19. LoJack (LOJN Quote), a Westwood, Mass., maker of security equipment, more than doubled its profits year over year to 32 cents a share -- a dime over estimates. Shares shot up $2.21, or 12.2%, to $20.31.
