Asian markets edged higher as beaten-down tech stocks regained favour after strong AMD results eased concerns over the durability of the AI trade. (EPA Images pic)SINGAPORE: US stock futures slid and the dollar softened on Wednesday as investors girded for results from US midterm election with the focus on whether Democrats can wrest control of Congress from President Donald Trump's Republicans.

Democrat Jon Ossoff won re-election in Georgia, marking the first significant race call of the night as polls closed in seven states.

Democrats are favoured to capture the ​House and both parties are locked in an intense state-by-state battle for the Senate, leaving investors and markets on edge.
