Indian equity markets ended Friday’s session lower, with the Nifty 50 declining 155.05 points, or 0.61%, to close at 25,144.30. The Sensex slipped 0.39% to 81,592.45.
An analysis of the November 13 NSE F&O Bhavcopy (DAT) showed that 129 of 218 near-month stock futures contracts witnessed short buildup, as declining futures prices coincided with rising open interest.
Another 36 stocks recorded long buildup, 35 showed long unwinding, and 17 registered short covering. One contract recorded an unchanged closing price despite a change in open interest.
The figures cover stock futures expiring on November 23, 2026.
Nifty and Bank Nifty Futures Show Long Unwinding
Nifty’s November futures contract closed at 25,171, down approximately 0.54% from its previous closing price. Open interest declined 0.64% to 1,19,82,035 units, signalling long unwinding under the conventional price–OI classification.
Bank Nifty futures exhibited a sharper contraction in outstanding positions. The November contract closed at 60,933.40, down 0.66%, while open interest dropped 6.63% to 20,51,220 units.
However, positioning differed in the deferred Nifty contracts. Open interest increased 1.96% in the December 29 futures series and 3.13% in the January 25 series while closing prices declined, a combination consistent with short buildup in those contracts.

Cholamandalam Investment and Finance recorded a 0.94% futures price decline alongside 7.18% higher open interest.
Manappuram Finance futures declined 3.52%, accompanied by 4.72% open-interest growth, while Shriram Finance futures fell 3.27% with open interest rising 4.50%.

Blue Star futures rose 0.44% while open interest declined 4.65%. ONGC futures gained 0.53%, with open interest falling 1.01%.
These price–OI combinations are consistent with short covering, although the data does not identify which participants closed positions.
ICICI Bank and IREDA See Long Unwinding
ICICI Bank futures declined 0.45% while open interest contracted 1.44%.
IREDA futures slipped 0.76%, with outstanding positions falling 2.92%. Kalyan Jewellers recorded a 2.16% futures decline alongside a 5.09% reduction in open interest.
Such combinations are commonly classified as long unwinding rather than the addition of fresh short positions.
What Does the November 13 F&O Buildup Indicate?
The predominance of short buildup across the November stock futures series suggests that declining prices accompanied expanding open interest in a substantial portion of the derivatives market.
However, futures open interest alone cannot identify whether the positions were initiated by foreign investors, domestic institutions, proprietary traders or retail participants.
Traders should monitor whether these price–OI trends persist in subsequent sessions, alongside trading volume, options positioning and changes in outstanding contracts across expiries.
