DII Buying Power Holds the Line Against FII Selling On August 6, foreign institutional investors sold a net ₹17.90 crore in the Indian cash segment. That number alone isn't alarming. What is alarming: FIIs simultaneously held 1,45,118 net short index-futures contracts, a position size that signals conviction, not hedging noise.
