U.S. Stocks Open Cautious; the Greek Parliament Votes Today on Reforms

U.S. stocks opened cautiously Wednesday as Greece's parliament votes today on the reform package that eurozone lenders say must be passed before it will loan the country bailout money. Meanwhile, Greek banks have been closed for 17 days. Bank of America (BAC) said its profits were strong as its legal costs plummeted. Delta Airlines (DAL) said its profits soared on lower fuel costs. The airline expects fuel prices to remain low for the rest of this year. Mortgage applications last week dropped 1.9% according to the Mortgage Bankers Association. Producer prices in June jumped .4%, more than what was expected. BlackRock (BLK) earnings and revenue beat expectations on higher base fees.
