Shares of

Encore Wire

(WIRE) - Get Report

were among the

Nasdaq's

losers Tuesday, falling 14.4% after the company posted third-quarter earnings and sales that missed Wall Street expectations.

The maker of copper electrical wire posted earnings of 27 cents a share on sales of $158.6 million. Analysts polled by Thomson First Call were expecting earnings of 33 cents a share on sales of $162.8 million. A year ago Encore earned 23 cents a share on sales of $113.9 million. Shares traded down $2.30 to $13.63.

ATA Holdings

(ATAH)

fell 36.3% after the parent company of ATA Airlines announced that Gilbert Viets would serve as the company's chief restructuring officer. The move fueled speculation that ATA is readying itself for a possible bankruptcy filing. Viets had most recently served as ATA's chief financial officer. David Wing will assume the role of CFO. Both changes are effective Oct. 19.

In August, ATA warned that it would likely run out of cash sometime in early 2005, resulting in asset sales or a restructuring. Last week the company said its financial problems had worsened. The dwindling cash position, the company said, "has been primarily the result of record fuel costs, continued weakness in overall revenue yields, and specifically in Florida as a result of multiple hurricanes." Finally, ATA said that a 10% wage cut approved by its flight attendants would "not be enough cost savings to satisfy these liquidity concerns." Shares traded down 53 cents to close at 93 cents.
