S&P 500 Futures steadied at 7,677.25 points, Nasdaq 100 Futures were flat at 29,184.50 points, while Dow Jones Futures were flat at 53,144.0 points

U.S. stock index futures moved little on Wednesday evening as caution over simmering tensions with Iran and potential increases in interest rates kept investors to the sidelines.

S&P 500 Futures steadied at 7,677.25 points by 23:30 GMT. Nasdaq 100 Futures were flat at 29,184.50 points, while Dow Jones Futures were flat at 53,144.0 points.

Futures steadied after a positive session on stock market, which recovered from a sluggish start to September. But overall gains were limited, with markets on edge before key labour market data due on Friday.

Broadcom Inc was a notable aftermarket mover, dropping slightly after a soft current-quarter forecast overshadowed better-than-expected fiscal third-quarter earnings. The company declined as much as 3% in aftermarket trade after the chipmaker’s fiscal fourth-quarter revenue guidance– at $34.8 billion– missed market estimates.

Concerns over stretched AI spending and increasing competition from rivals such as Marvell Technology Inc weighed heavily on Broadcom in recent months.

Among other major aftermarket movers, Hewlett Packard Enterprise Co slipped over 5% after the company flagged some potential weakness in its margins, as well as supply chain bottlenecks.

Stock indexes rose on Wednesday, aided in part by Treasury yields dropping from recent highs, while a rally in oil prices also cooled.

Stock market was nursing a rough start to September, especially after a recent resurgence in Iran-U.S. tensions over the Strait of Hormuz.

The two traded strikes for the first time since late-July, sending oil prices soaring. This in turn added to concerns over sticky inflation and higher interest rates.

Hawkish comments from the central bank also weighed, amid growing conviction that the central bank will raise interest rates in September.

Focus this week is squarely on nonfarm payrolls data for August, due Friday, for more cues on the labour market and rates. Strength in employment gives the central bank more headroom to raise interest rates.
