US stocks tumbled Tuesday with the Dow and the NASDAQ ending lower for the fourth straight day as investors became wary of corporate earnings looking softer than forecasted based on a string of weak results by technology companies.
Stocks opened strong earlier over news that EU finance ministers agreed late Monday to release an initial €30 billion to Spain by the end of July to help the country shore up its stricken banks.
Treasury 10-year yields slipped as refuge appeal of US assets rose amid concerns the European debt-crisis is deepening after Bank of England Governor Mervyn King said British economy may slip further into a double-dip recession if European leaders fail to act fast. Sentiments soured further after a US survey of small business optimism came in softer than anticipated.
