US stocks sank Thursday on the second consecutive day of disappointing news from a major central bank. European Central Bank President Mario Draghi last week sent stocks higher with his remark that the ECB would do \"whatever was needed to preserve the euro.\" In Frankfurt, Germany, Thursday, Draghi said the ECB\'s Governing Council had elected to keep the key lending rate at 1 percent and stood ready to take other measures in the future. Policy makers at the U.S. Federal Reserve, although with less implied promise of changes, announced they would stick with their established policies Wednesday, which also disappointed investors.
