Stock market today: Live updates

The S&P 500 and Nasdaq Composite pulled back from fresh all-time intraday highs on Thursday, with Wall Street taking a breather from its recent gains as the U.S. government shutdown continues on.

The broad market index and the tech-heavy index each dropped 0.3%. At their highs of the day, the S&P 500 and the Nasdaq were up 0.2% and 0.1%, respectively. The Dow Jones Industrial Average, meanwhile, declined 180 points, or 0.4%.

The government shutdown moved into its ninth day Thursday as the Senate is slated to vote for a seventh time on dueling funding proposals. Republicans need at least eight Democrats to join them in voting in favor for the legislation so that their short-term funding bill can meet the 60-vote threshold required for passage.

This comes as investors’ concerns that the stoppage will mean a hit to the U.S. economy have already started to materialize. On Wednesday, the IRS said that it was going to furlough nearly half of its workforce as a result of the shutdown. On top of that, a shortage of air traffic controllers has led the Federal Aviation Administration to delay U.S. flights.

Delta Air Lines CEO Ed Bastian told CNBC Thursday that while he hasn’t seen “any impacts at all” from the shutdown, “some impacts” could begin to appear “if this doesn’t get resolved, say beyond another 10 days or so.” The stock was a winner during Thursday’s session, jumping 5% on better-than-expected earnings.

Costco was another one of the bright spots of the day, as shares gained 2% after the big-box retailer delivered solid September sales data.

The S&P 500 on Wednesday notched its eighth winning day of the last nine. The Nasdaq climbed more than 1% to end above the 23,000 mark for the first time ever.

The Dow, on the other hand, finished slightly below flat as blue-chip stocks lagged. But Nvidia helped the 30-stock index restrict losses, rising more than 2% after CEO Jensen Huang told CNBC that computing demand has “gone up substantially” this year.

“There are reasons to be optimistic ahead, but I wouldn’t be surprised to see some more volatility,” Kevin Mahn, investing chief at Hennion & Walsh Asset Management, said on CNBC’s “Closing Bell Overtime.” “When that volatility comes, money will come off the sidelines.”

There are no economic data releases of note on Thursday due to the ongoing government shutdown.
