Shares of

Nike

(NKE) - Get Report

were among the

NYSE's

winners Friday, rising 6.8% after the company posted second-quarter earnings that easily topped expectations.

The footwear and apparel maker earned $261.9 million, or 97 cents a share, on sales of $3.14 billion. Analysts surveyed by Thomson First Call were expecting earnings of 86 cents a share on sales of $3.11 billion. A year ago the company earned $179.1 million, or 66 cents a share, on sales of $2.84 billion. Nike said that business in the United States, coupled with strong growth in emerging markets such as China, Russia, and Turkey, plus favorable European exchange rates, led to much of the growth during the second quarter. Shares traded up $5.80 to $91.70.

SPX

(SPW)

fell 3.6% after the company lowered its 2004 operating earnings outlook and warned that free cash flow would fall significantly from the company's previous guidance. The diversified manufacturing company said that income would fall to $486 million, more than $100 million below its previous guidance, in part because of an $80 million writedown related to the sale of its Edwards Systems Technology unit.

SPX also said it expects free cash flow (cash from continuing operations less capital expenditures) to be about $80 million in 2004, which is a "significant reduction" from its previous target, the company said. The drop in free cash flow is the result of declining operating profit along with a decision by the company to discontinue factoring and other accounts receivable programs. Shares traded down $1.47 to $39.03.

Shares of

Circuit City Stores

(CC) - Get Report

fell 3.7% after the company posted third-quarter loss that was smaller than expected, but warned that it is cautious about the fourth quarter. The consumer-electronics retailer posted a loss of $5.9 million, or 3 cents a share, on sales of $2.49 billion. Analysts were expecting a loss of 8 cents a share on sales of $2.51 million. Though Circuit City's third-quarter earnings results topped expectations, the company said it was "disappointed" with its sales results. "Considerable opportunity remains for improvement throughout the company," it said. Looking ahead, Circuit City said that it is cautious about its fourth-quarter outlook. "We saw a general sales weakness as the market was more promotional than we anticipated, particularly in the second half of the quarter," it said. Shares traded down 56 cents to $14.72.

(ZOLT)

rose 21.9% after the company landed a deal to provide Denmark's
