Shares of Domino's Pizza ( DPZ) were among the NYSE's losers Tuesday, tumbling 13% after the pizza maker missed third-quarter estimates and said the U.S. operating environment remains "challenging." Domino's said its third-quarter dropped 55% to $11 million, or 17 cents a share. Revenue inched up 3.3% to $337.3 million. The results fell short of analysts' expectation for earnings of 23 cents a share and revenue of $351 million, according to Thomson Financial. Domino's said "unprecedented cost pressures" and a weak consumer environment hurt its U.S. results. Shares recently were down $2.11 to $14.45. Tetra Technologies ( TTI) also was on the decline after the oil-and-gas services concern withdrew its 2007 earnings guidance. The company had previously projected earnings of $1.30 to $1.50 a share, but it said issues such as impairment charges and a lack of insurance recoveries will hit results. Shares tumbled $1.74, or 8.1%, to $19.88. Among the winners, Lululemon ( LULU) shares jumped 17% after the yoga-wear maker boosted third-quarter targets. The company said that earnings for the period should top its prior guidance of 5 cents to 6 cents a share. Analyst, on average, projected earnings of 6 cents a share. The company attributed the improved outlook to a strengthening Canadian dollar and robust sales. Lululemon said same-store sales rose in the mid-30s percentage over a year earlier, compared with its guidance for growth in the mid to high teens. Shares were adding $7.09 to $48.22.
