Equity benchmark indices continued their rally in early trade on Wednesday amid buying in banking counters, a largely positive trend in other Asian markets and continuous foreign fund inflows.

Elsewhere in Asia, markets in Seoul, Shanghai and Hong Kong were trading higher while in Tokyo, shares were trading lower.
Wall Street had ended on a mixed note on Tuesday.
"An important feature of the ongoing rally which has taken the Sensex and Nifty to record highs is that this is a mature rally led by high quality stocks in performing sectors," V K Vijayakumar, Chief Investment Strategist at Geojit Financial Services, said.
Also, the US Federal Reserve Chairman Jerome Powell's speech on Wednesday will be closely watched by global markets for cues on rate hike trajectory.
