Analysis what the data is telling us about NATIONALUM
In the last completed session, National Aluminium Co. Ltd. closed +2.78% with futures open interest moving -2.8%. That combination — price rising while OI shrinks — is classified as Short Covering. It typically reflects existing short sellers closing positions, not fresh buying. Short-covering rallies can be sharp but tend to fade without follow-through demand. The stock's option PCR sits at 0.66, indicating heavy call-side writing — option dealers see resistance overhead. Max-pain strike at ₹380 sits 3.7% below 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 National Aluminium Co. Ltd. over the last 30 sessions.
Putting it together, the smart-money picture for National Aluminium Co. Ltd. leans constructive into the next session.
