FII Cash Buying Masked by F&O Hedging: Nifty at Risk

FII Cash Inflows Don't Tell the Whole Story On the surface, July 4 looked like a constructive day for Indian equities.

On days when FII cash buying is paired with derivatives hedging, NIFTYBEES often sees muted price action even when the underlying cash market shows buying. That's because arbitra...
