Small stocks vaulted higher than the broader market on Wednesday, largely on positive earnings from names such as TTM Technologies ( TTMI). 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), a business-software firm, and Mountain View, Calif., semiconductor company Cavium Networks ( CAVM). 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), 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), 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.
