XL Capital ( XL) was up 2.5% after the Bermuda-based insurance company said it expected losses relating to Hurricane Katrina to be about 1.75% of the industry loss, which the company said is consistent with its expectations.

Everest Re ( RE) rose 2% after the Bermuda-based reinsurance company said it expected to turn a profit this year, even though its losses from Hurricane Katrina could amount to about 1% of the total industry losses. The company also said it expected capital growth in December. Joseph V. Taranto, the company's chief executive, said that the impact of Hurricane Katrina "is within our risk-management tolerance and does not change our positioning or underlying fundamental financial strength." Shares of Everest were up $1.86 to $96.36.

Mercury General ( MCY) fell 1% after Citigroup downgraded the Los Angeles-based insurance company from buy to hold.

Shares of Mercury General were down 57 cents to $59.15.

ACE ( ACE) rose 2.7% after the Bermuda-based insurance and reinsurance company said late Monday that early estimates indicate that its losses related to Hurricane Katrina will range from $450 million to $550 million.
