Nash Finch ( NAFC) was among Nasdaq's losers Friday, with shares plunging 26% after the food retailer and distributor cut its 2005 earnings outlook.

The company now expects earnings of $3 to $3.25 a share, down from an earlier view of $3.70 to $3.89 a share. Analysts polled by Thomson First Call had projected earnings of $3.74 a share. "Clearly the acquisition of the Westville, Ind., and Lima, Ohio, divisions earlier in the year resulted in a lack of focus in our core business," the company said. "We have experienced serious erosion in retail and wholesales gross profit margins, based on issues that we had thought were readily resolvable. Unfortunately, the impact has been deeper than we anticipated and margins will take longer to rebound than we had thought, but these issues are fixable and we are addressing each one of them." Shares recently dropped $10.96 to $31.38.

Shares of Cree ( CREE) rose 15% after the maker of light-emitting diodes posted better-than-expected fiscal first-quarter results.
