Mattel ( MAT) fell after Banc of America Securities downgraded the shares to sell from neutral and lowered its price target to $13 from $18.50. Sluggish retail sales of the Barbie brand and weaker margins prompted the downgrade. What's more, the analyst said a strengthening U.S. dollar, high commodity costs and competition are likely to weigh on the company. Banc of America lowered its 2004 earnings expectations to $1.13 a share from $1.18 a share, and 2005 earnings expectations to $1.08 a share from $1.20. Shares of Mattel traded down 36 cents, or 2%, to $17.57.

Shares of World Airways ( WLDA) rose as much as 33% after the company said it signed a letter of intent to lease two MD-11F cargo jets early next year but gave back all of its gains by the end of the trading day. It said the added capacity would allow it to keep up with growing demand in its international cargo market. The two cargo jets will bring the company's MD-11 fleet to five cargo jets and eight passenger aircraft for international service. It expects to take delivery of the cargo jets some time during the spring of 2005. Shares of World Airways traded down 27 cents, or 6%, to $4.26.
