Fed Chair Powell is due to make a speech at 10 a.m. ET of USA time (7:30 PM IST) on Friday at the Jackson Hole symposium. China stepped up stimulus with a further 1 trillion yuan ($146 billion) of measures. Nifty remained in a very small range through the day and could not breach the high of the previous day. Once that level i.e., 17,626 is breached, more upsides could be in store in this up move.
