Updated from 9:43 a.m. EDTStocks were sulking Thursday, as traders waited for the House of Representatives to follow up on the Senate's recent passage of a $700 billion bailout plan for financial firms. The Dow Jones Industrial Average dropped 229 points to 10,602, and the S&P 500 was losing 29 points to 1132. The Nasdaq was slipping 56 points to 2013. After the close of Wednesday's trading, the Senate passed the bailout bill with a 74-25 vote. The House of Representatives had rejected an earlier version of the proposal on Monday, and the stock market responded with one of its worst performances in recent memory. Among other revisions, the bill passed by the Senate included $110 billion in tax incentives aimed at fostering economic growth. The House is expected to vote on the revised package Friday. "I think, honestly, the Senate was kind of a foregone conclusion," said Michael Church, portfolio manager at Church Capital Management. He said that the real hurdle for the rescue package has been in the House, where local interests are holding lawmakers back from passing the bill. "You look at some of the stuff that got thrown on that thing, you have to shake your head and say that some of these guys are being bought," he said. Church also said that sentiment is so awful that a short-term surprise rally isn't out of the question. In an attempt at offering additional support to the stock market, the Securities and Exchange Commission extended through Oct. 17 a ban on short sales of financial stocks. The original ban had been slated to expire today.
