Share Market Updates Today: Indian equity benchmarks are expected to open on a flat note today as investors wait for gross domestic product GDP data and US Federal Reserve Chairman Jerome Powell's speech, which is due later in the day, to hear about future interest rate hikes. GDP data for the July-September quarter is scheduled to be released on Wednesday at 5: 30 pm.
