Futures narrowly mixed as Syria worries ease

U.S. stock index futures hovered around the flatline Friday as month-end buyers stepped in and as fears of imminent military action against Syria eased.

The Dow and S&P 500 are poised to log their worst monthly declines since May 2012.

The U.K. voted against joining any military action in Syria on Thursday, in a move some saw as likely to delay any strike. However, the White House said that President Barack Obama will decide on a response to Syria based solely on U.S. interests, although he will consult with Britain.

"While the U.K. parliament vote against military action in Syria may make it seem air-strikes are less likely, the argument could be made in the U.S. that they are unlikely to generate further quick international support, and waiting to debate it further may achieve little but appear to lack resolve," wrote Greg Gibbs, a senior foreign-exchange strategist at RBS.

"If the U.S. administration is leaning in favor of air strikes, the best timing is as soon as the U.N. inspectors leave the country on Saturday," he added.
