Two institutional forces drive Indian markets: FIIs (~17% of market cap) and DIIs (mutual funds, insurance). FII flows are driven by DXY, US rates, and risk appetite. DIIs provide stability through ₹18,000+ Cr monthly SIP flows. Track NSDL daily data, quarterly shareholding patterns, and bulk/block deals for institutional conviction signals.
Key points
FIIs hold ~17% of market cap — their flows drive short-term direction
DIIs (SIPs ₹18K+ Cr/month) create a buying floor during corrections
FII selling + DII buying = temporary correction (usually recoverable)
FII selling + DII selling = crash (structural risk — be cautious)
DXY > 105 typically triggers FII outflows from India
Quarterly shareholding changes reveal institutional conviction building
Bulk deals > 0.5% signal large player conviction
Example — Oct 2022: FIIs sold ₹17,000 Cr due to US rate hikes. NIFTY fell from 18,000 to 16,800. DIIs absorbed ₹15,000 Cr via SIPs. Within 4 months, NIFTY recovered to 18,500+ as FIIs returned.
Pro tip — Track: (1) Monthly FII flows, (2) DXY level, (3) US 10Y yield, (4) India VIX. When FII selling is extreme, DXY peaking, yields topping, VIX > 20 — a market bottom is forming.
