U.S. stock index futures edge higher, Tesla and other companies will announce financial reports.

US stock index futures rose before the bell on Wednesday as traders assessed the latest developments in the Middle East. Earlier, President Donald Trump announced an indefinite extension of the cease-fire arrangement with Iran. As of 8:02 a.m. New York time, S&P 500 index futures rose 0.6%, with the index poised to rebound after two consecutive trading days of declines. Nasdaq 100 index futures rose 0.8%, Brent crude oil rose 0.64% to $99 per barrel. The Chicago Board Options Exchange Volatility Index (VIX) hovered around 19. AJ Bell Investment Director Russ Mould said, "Donald Trump has released conflicting information and insists that the US will continue to implement sanctions on Iran, meaning investors are still speculating on the situation."
