Wall Street takes a hit from ECB disappointment

Traders work on the floor of the New York Stock Exchange, July 26, 2012.

NEW YORK (Reuters) - Stocks fell for a fourth day on Thursday after European Central Bank President Mario Draghi disappointed investors hoping for immediate action to contain the euro zone debt crisis.

One of Wall Street's top market makers, Knight Capital Group (KCG.N), was fighting for its survival after a trading glitch that roiled markets on Wednesday wiped out $440 million of the firm's capital.

However, the market focused mostly on the ECB, though traders were also looking ahead to Friday's closely watched U.S. jobs report which could bring a volatile end to an eventful week.

Draghi said the ECB would gear up to buy Italian and Spanish bonds on the open market but would only act after euro zone governments have activated bailout funds to do the same, disappointing traders after his pledge last week to do "whatever it takes" to save the euro left many thinking action was imminent.

"Today people were looking for concrete steps and an outline of exactly what path the ECB would take to do that, and there weren't any," said Brian Gendreau, market strategist with Cetera Financial Group in Gainesville, Florida.

"Just as the market went up on the 'whatever it takes' comments it is coming down on the lack of specificity."

Markets rallied late last week in part on hopes for stimulus from the Federal Reserve but mostly as expectations grew the ECB would take action to protect the euro. Friday's jobs report could give a stronger indication whether the Fed, which has a freer hand than the ECB, will act shortly.

Data showed the number of Americans filing new claims for jobless benefits rose last week and manufacturers suffered an unexpected drop in orders in June, suggesting the economy is struggling to break out of a soft patch.

The Dow Jones industrial average .DJI fell 92.18 points, or 0.71 percent, to 12,878.88. The S&P 500 Index .SPX dropped 10.14 points, or 0.74 percent, to 1,365.00. The Nasdaq Composite .IXIC lost 10.44 points, or 0.36 percent, to 2,909.77.

Major indexes fell for a fourth day running, totaling weekly losses so far of more than 1.5 percent.

Knight Capital shares fell after Wednesday's trading error forced the company to seek new funding. The stock closed down 62.8 percent at $2.58, their lowest since early October 1998.

According to Thomson Reuters data, 67 percent of the 385 S&P 500 components that have reported results so far this quarter have beat earnings estimates. In the past four quarters, the average beat rate has been 68 percent.

General Motors Co (GM.N) posted a smaller-than-expected loss in Europe that helped the No. 1 U.S. automaker post a better-than-expected second-quarter profit. Shares slipped 2.6 percent to $19.14.

Gap Inc (GPS.N) jumped 12.8 percent to $33.17 after the clothing retailer posted its July and second-quarter sales, but rival Aeropostale (ARO.N) plummeted 32.8 percent to $13.08 after cutting its second-quarter forecast.

U.S. retailers reported stronger-than-expected sales for July but the gains were largely due to discounting and do not necessarily signal vigorous consumer spending for the rest of the year.

About 7.1 billion shares exchanged hands on the New York Stock Exchange, NYSE MKT and Nasdaq, above the year-to-date daily average of 6.75 billion.

About 8 issues fell for every 5 that rose on the NYSE and on Nasdaq the decline/advance ratio was roughly 7 to 5.
