"We had the Treasury saying it would be an apocalyptic event. Then we had (House Speaker John) Boehner say: 'I'm not going to let it happen.' I think investors were pulled and tugged today between extreme rhetoric," said Jack Ablin, CIO at BMO Private Bank.
The market recovered some of its losses around midday Thursday when Boehner was reported to have told Republicans that he is determined to prevent a default and is willing to pass a measure through a combination of GOP and Democratic votes if need be. But then stocks dipped again on reports the Capitol Building was under lockdown due to a shooting event, and there was little information available initially. It later was reported that police shot a woman who tried to ram a car into a White House gate and then drove to the Capitol.
Stocks finished lower, with the S&P 500 down 15 at 1678, and the Dow off 136 at 14,996. Short-term Treasury yields rose on concerns about the debt ceiling. The yield on the one-month T-bill reached 0.17 percent, its highest level since November.
Friday could see a ripple of excitement from Twitter's $1 billion IPO filing, which came out Thursday after the bell. IPOs are seeing a resurgence, with 160 deals through the third quarter, compared to 142 for all of last year, according to PricewaterhouseCoopers' IPO Watch.

PwC expects the momentum to continue and the year should see the highest level of IPO activity since 2007.
What to Watch?
The lack of a jobs report leaves a question mark for traders, who were looking forward to the employment report as another piece of information to help them handicap possible Fed action on its bond buying program. The Fed in September held back from tapering its $85 billion monthly bond purchases, because of concerns about financial conditions, the economy and fiscal uncertainty.
"It's typically a big number. It's going to be a pretty big non-event, and it's not just the jobs number. About a third of all data that investors track comes from affected government agencies," said Ablin. "Probably the short-term guys are going to watch from the sidelines. There's nothing to sink your teeth into so anything you do is just guess work."
"We're just left to blow in the wind," said John Briggs, head of cross asset strategy at RBS. "The market will probably be choppy."

Barry Knapp, head of equity portfolio strategy at Barclays Capital, said the market will start to focus on earnings next week, even with the showdown in Washington. Former Dow component Alcoa reports Tuesday, and J.P. Morgan will be the first Dow member to report earnings with its report Friday.
"The market will be a little squishy between now and the beginning of earnings season," Knapp said. "The market performance for the two weeks following Alcoa's earnings report has averaged up 1.3 percent since the recession…It's been a pretty favorable period."
Knapp said the feuding in Washington is not likely to end with the U.S. breaching the debt ceiling. "By mid-week next week, if the polls aren't pointing to a victory for one side or another, they'll start negotiating," he said. He said a deal would probably be positive for stocks.
The markets Friday may be sniffing out a possible weekend surprise though the odds don't seem high.
"It's not like you're going into the weekend risk and you're afraid. If we walk in on Monday, and nothing's changed, that's kind of expected. I don't think things are going to rally, but I just don't think you're going to have a typical 'risk off' into the weekend," Briggs said. "The weekend risk could actually be good news."
