Shares of New Century Financial ( NEW) were among the NYSE's losers Friday, falling 9% after the real estate investment trust cut its 2005 earnings outlook. The company now expects earnings of $7.25 to $7.75 a share, down from previous guidance of $8.25 to $9 a share. Analysts polled by Thomson First Call had been expecting earnings of $8.12 a share. New Century blamed its revised outlook on weakened operating margins, which were caused by a "significant deterioration in the secondary market for loans," it said. The company said that it would still generate earnings that would support its dividend of $6.50 a share in 2005 and its dividend of $7.30 a share in 2006. Finally, New Century said that its current guidance does not reflect the impact of weather-related losses in the Gulf Coast region. The losses, which can't be determined at this point, could possibly be significant, the company said. Shares were trading down $3.35 to $35.60. IPC Holdings ( IPCR) fell 7% after the insurance company said that Hurricane Katrina would significantly impact its third-quarter results.

Shares were trading down $2.29 to $30.32. Shares of Darden Restaurants ( DRI) rose 7% after the company posted first-quarter earnings that topped forecasts by a penny.
