Fred Anderson and Roger McNamee, managing directors and co-founders of Elevation, will join Homestore's board of directors. "Homestore fits perfectly with our investment strategy. The online real estate media opportunity is very large and Homestore is the undisputed leader in the category," Anderson said in a statement.

The preferred stock is convertible into Homestore's stock at $4.20 a share. If converted, the investment would represent about 14% of Homestore's outstanding shares. Homestore plans to use the proceeds for general corporate purposes. Shares were recently trading up 43 cents to $3.99.

Conn's ( CONN) rose 8% after the home-appliance and electronics retailer reported strong third-quarter sales results. Sales for the quarter rose to $153 million from $115.1 million in the year-ago period. Same-store sales, meanwhile, climbed 23.2%. The retailer, which operates stores in Texas and Louisiana, said hurricanes Katrina and Rita resulted in the loss of 134 store days, but sales were ultimately helped by the disasters as customers replaced damaged appliances and electronics.

Shares of Lafarge North America ( LAF) fell 9% after the construction materials company posted third-quarter results that were weaker than expected. The company earned $172.1 million, or $2.17 a share, on sales of $1.42 billion. Analysts expected earnings of $2.52 a share on sales of $1.49 billion. For last year's period, earnings were $165.6 million, or $2.16 a share, on sales of $1.23 billion. "Increased inflation, reduced cement plant production, and weather disruptions offset the gains we wanted to achieve this quarter," the company said.

Looking ahead, Lafarge said that higher energy prices and inflation are expected to pressure margins the rest of the year. Still, the company said that it expects strong pricing power to continue and has announced additional price increases for 2006.

Finally, Lafarge announced a new $100 million stock buyback plan that will begin on Jan. 1 and run through Dec. 31, 2006. Shares recently shed $5.25 to $55.10.

As for the buyback plan, the company has been authorized to repurchase up to 34 million shares through the end of 2006.

TXU, which raised its 2005 outlook last week when it reported third-quarter earnings, continues to expect full-year operational earnings of $3.25 to $3.35 a share, or $6.50 to $6.70 on a presplit basis.
