Analysis what the data is telling us about IOC
In the last completed session, Indian Oil Corporation Ltd. closed +0.05% with futures open interest moving +1.0%. That combination — price rising while OI builds — is classified as a Long Buildup, meaning derivative traders are adding fresh bullish positions into strength rather than merely covering existing shorts. The option PCR of 0.80 is balanced — no clear directional preference from option writers. Max-pain strike at ₹132 sits 1.7% above the current price, a mild magnet near expiry.
There have been no notable bulk or block deals from FIIs, mutual funds, or insurance companies in Indian Oil Corporation Ltd. over the last 30 sessions.
Putting it together, the smart-money picture for Indian Oil Corporation Ltd. leans constructive into the next session.
