TORONTO, July 24 (Reuters) - The Toronto Stock Exchange's main index sank more than 2 percent on Thursday in a broad decline sparked by losses in financial-services shares as sour data highlighted concerns over the U.S. economic outlook.

Agnico-Eagle Mines (AEM.TO: Quote, Profile, Research, Stock Buzz) was among the biggest decliners by weight, losing 7.8 percent, after it reported a weaker than expected quarterly profit, a lower production outlook for the year, and warned of a jump in project costs over the next two years.

All of the major banks were down, including Canadian Imperial Bank of Commerce, which lost 5.9 percent.

The financial-services sector dropped back from this past week's strong rally, taking its cue from U.S. bank stocks, which fell after data showed a drop in sales in existing U.S. homes.
