Stock Market News: Dow Opens Down on Columbus Day

The rest of the market is trying to follow AI stocks.

The Dow was up 24 points, or 0.1%, after trading lower so far. The S&P 500 was up 0.6% and the Nasdaq was up 0.9%.

Though AI-linked stocks are still dominating the top performers in the S&P, roughly 353 stocks in the index were on track to rise. That’s also an improvement from earlier in the morning.

The Invesco S&P 500 Equal Weight ETF, a measure of breadth because it weighs every stock in the S&P the same, was up 0.4%.

Expect some light—and potentially wacky—trading today.

Because it’s the Columbus Day holiday, some on Wall Street may be taking a long weekend. U.S. bond markets are also closed for the today.

The New York Stock Exchange and Nasdaq combined average 5.83 billion shares traded on Columbus Days, going back to 2015. That compares to an average daily volume in that span of 7.27 billion and an average 2024 day of 9.68 billion.

Lower volume days can prompt sudden market moves since there’s less activity to absorb the shock of larger trades
