DoubleClick (DCLK) was down 11.2% in preopen Island trading. After the close Thursday the Internet ad agency posted a first-quarter loss of 8 cents per share excluding items, ahead of the Thomson Financial/First Call consensus of a 9-cent loss and the year-earlier 11-cent loss.

But the company warned that it will lose more money than expected in the second quarter as the slump in online advertising continues.
