This apart, reports suggesting India is likely to impose retaliatory tariffs on $10.6 billion worth of goods imported from the US will also be closely monitored. Fresh directional cues from US-China trade negotiations, movement of rupee against the US dollar and crude oil prices are the other key events that will impact investor sentiment today.

GLOBAL MARKETS Asian stocks were trading mixed in the early trade on Wednesday, as investors awaited fresh directional cues from US-China trade negotiations and a weaker Wall Street finish capped broader gains, while robust US economic data supported the dollar.
