The dollar rebounded as news from Ireland, Portugal and Greece renewed concerns about the financial stability and dented the euro.
"We had a lot of good news on Friday, including a weak dollar that helped a lot of commodities and multinationals. That we are seeing reversed today," said Marc Pado, U.S. market strategist at Cantor Fitzgerald & Co. in San Francisco.
"Ireland's budget issues and concerns over Spain and whether the whole sovereign debt crisis continues to unfold in a negative manner are hurting the euro, boosting the dollar and weighing on stocks." http://news.yahoo.com/s/nm/20101004/bs_nm/us_markets_stocks
