NEW YORK (AP) - Stocks inched higher on Wall Street Friday but investors remain focused on Washington, where a partial shutdown of the U.S. government has weighed on the market all week.
The Dow Jones industrial average was up 23 points, or 0.2 percent, at 15,020 as of 11:20 a.m. Eastern. The Standard & Poor's 500 index was up five points, or 0.3 percent, at 1,683 and the Nasdaq composite index was up 20 points, or 0.6 percent, at 3,795.
Despite Friday's modest gains, the trend for the last three weeks in the stock market has been lower. The Dow is down nearly 3 percent since hitting an all-time high on Sept. 18.
Washington appears no closer to resolving the government shutdown or the looming deadline later this month to increase the government's borrowing limit so it can continue to pay its bills. On Friday, Republicans in the House of Representatives said they would continue to pass small spending bills that fund select parts of the government, such as Head Start, but that tactic has found little traction with the Democrats in the Senate.
"The intransigence on both sides has created a very difficult situation," said Stephen Auth, chief investment officer of equities at Federated Investors.
Under normal circumstances, investors would have the government's monthly jobs report to parse through on Friday. But the shutdown has forced the Labor Department to postpone the release of September's data for at least the foreseeable future.
Parts of the bond market are starting to show stress as the Oct. 17 debt ceiling deadline nears. Yields for the one-month T-bill that mature around the time the U.S. government is expected to hit its borrowing limit have risen to their highest level in a year. The yield on one-month T-bill was 0.14 percent, up sharply from 0.01 percent five days ago.
Bond market observers said that fund managers for money market funds, who primarily invest in these types of securities, have been selling short-term Treasuries. Fund managers don't want to be stuck holding U.S. government debt maturing around the time the federal government hits its borrowing limit.
Despite these concerns, Federated's Auth said he believes the possibility that the U.S. government would willingly default on its debt is remote.
"It's hard to really say how this going to end, but I think it's unthinkable that it will end with a default of the U.S. government," Auth said.
