India's BSE Sensex reversed early losses to close about 0.4% up at 77,656 on Tuesday, following a downbeat session the previous day, helped by the recovery in financials and IT stocks. Lower oil prices also supported sentiment, while Washington’s latest measures to increase economic pressure on Iran were less severe than markets had anticipated. Foreign portfolio inflows have provided some support, with foreign investors buying more than $2.5 billion of Indian equities so far this month. Investors now awaited Nvidia’s earnings on Wednesday and Fed Chair Kevin Warsh’s Jackson Hole speech on Friday for fresh clues on the monetary policy outlook.
