08:13 AM EDT, 10/23/2024 (MT Newswires) -- US stock futures are moving lower in Wednesday's premarket session ahead of existing home sales figures, crude oil inventories, and a speech by Federal Reserve board member Michelle Bowman expected later in the morning.

The Dow Jones Industrial Average futures were down 0.48%, the S&P 500 futures were off 0.21% and Nasdaq futures were moving 0.33% lower.

Existing home sales for September, released by the National Association of Realtors, are expected to rise to 3.88 million from 3.86 million in August, according to Bloomberg. The report can be an indicator of the US housing market's condition as well as a gauge of overall economic strength.

Crude oil inventories from the Energy Information Administration, which measures the weekly change in the number of barrels of commercial crude oil held by US firms, are expected to come in at 700,000, compared with -2.2 million the previous month, according to Bloomberg.

And Michelle Bowman will be speaking later in the morning at the Eighth Annual Fintech Conference. Investors will be looking to see if she will drop any hints as to the Fed's future movements regarding interest rates. Last month Bowman said she dissented the Federal Open Market Committee's decision to cut rates by half a percentage point in favor of a quarter-point cut.
