FIIs Turn Net Sellers After 6-Day Streak: What Now?

FIIs Flip to Sellers — But the Derivatives Tell the Darker Story Foreign Institutional Investors turned net sellers on August 5, 2026, dumping ₹943 crore worth of Indian equities in the cash segment after six straight sessions of buying. On the surface, that looks like a routine pause. Don't be fooled. The real signal isn't the cash outflow. It's what FIIs have been doing in derivatives all along.

If markets rally sharply, FIIs face mark-to-market pressure on their F&O book and may be forced to cover, which would paradoxically fuel a short-covering rally. That's the two-sided risk sitting under the surface right now. NSE: NIFTY closed the August 5 session under pressure, with the index struggling to hold key support around the 24,500 zone. NSE: BANKNIFTY has been the more vulnerable index, given...
