Stocks were roughly flat on Thursday, taking a breather after the S&P 500 index rose to all-time highs in the previous session.

The S&P 500 gained 0.1%. The Nasdaq Composite also traded 0.1% higher. The Dow Jones Industrial Average climbed 45 points, or 0.1%.

Tilray up 21%; Akero Therapeutics up 17%; Serve Robotics up 12%; Delta Air up 8%; Nvidia up 2%; Ferrari down 13%

Costco shares gained more than 1% after the big-box retailer delivered solid September sales data, with total net sales for the five weeks ended Oct. 5 posting a notable increase versus last year.

With Wednesday’s gain, the S&P 500 notched its eighth winning day of the last nine. The technology-heavy Nasdaq Composite 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 is no economic data releases of note on Thursday due to the ongoing government shutdown.

However, investors will monitor morning remarks from Federal Reserve Chair Jerome Powell at a community bank conference, as well as speeches from other Fed officials such as Michelle Bowman and Mary Daly throughout the day. These appearances come a day after the Fed released minutes for its most recent policy meeting showing divisions around what to do next with interest rates.
