October F&O Rollover Analysis: Stocks to Watch for November

October's expiry looked quiet on the surface. NIFTY ended the series almost flat, up just 0.15%. Underneath, traders pulled money out of stock futures across the board. Total open positions in stock futures fell to ₹4.82 lakh crore, the lowest level in the last few months.

Only 58 of 213 F&O stocks ended the series higher. The rally was narrow: IT did the heavy lifting, banks held steady and most other sectors were sold.

For November, we suggest selective buying, not broad buying. Stick to stocks where fresh buying positions are visible. Avoid stocks where traders are adding short bets.

What rolled over, and what didn't

Rollover is the share of expiring positions that traders carry into the next month. High rollover means traders want to stay in the trade. Low rollover means they are closing out.

Three things stand out:

• BANKNIFTY rollover hit a seven-month high. Traders are willing to carry bank index positions into November. That is the strongest conviction signal in this expiry.
• NIFTY rollover was below average. Traders are less committed to the broad index.
• Stock rollover held steady at 91.1% (90.8% in September). People who stayed in stock positions kept them. Fewer people are in the trade overall.

The hedge ratio: why it rose

The hedge ratio compares money in stock futures with money in NIFTY futures. A high number means traders hold a lot of stock bets relative to their index hedges, so they are more exposed if the market falls. We treat above 12x as a caution zone and below 10x as comfortable.

October: 12.6x (September: 11.5x)

The ratio rose, but not for a worrying reason. Traders did not buy more stocks. They cut NIFTY futures by about 12%, faster than they cut stock futures (about 4%). Fewer hedges against slightly fewer stock bets pushes the ratio up.

The ratio is back above the 12x line, so caution is warranted. It is still well below the 14.7x peak seen in July. 

Sector view

Technology: a strong rally, mostly short covering

IT was the standout sector, up 13% in the series. Open positions in the sector actually fell, though. That means much of the rally came from traders closing short bets (short covering), not from new buyers coming in.

• TCS rose 22.9%, but open positions fell 29.1% and rollover dropped to 80.7% from 93.6%. The rally has not yet been backed by fresh buying.
• WIPRO (+19.3%), COFORGE (+16.0%) and HCLTECH (+16.2%) show the same pattern: sharp gains while positions were cut.
• PERSISTENT is the exception. It rose 13.0% while open positions rose 15.8%, with 64% of traded shares taken for delivery. That is genuine new buying.

Our view: Respect the move, but don't chase the short-covering names. PERSISTENT is the cleanest setup in the sector.

Banking: the steady anchor

Banking is the largest sector in stock futures, at about 22% of all positions. Rollover held at 92.2%, and BANKNIFTY rollover was the highest in seven months.

• UNIONBANK rose 11.2% with open positions up 8.4% and rollover at 96.6% (up from 93.0%). This is a classic long build-up, meaning new buying alongside rising prices.
• PNB rose 8.5% with a small increase in positions.
• AXISBANK (95.3% rollover) and SBIN (93.8%) were carried forward strongly despite flat-to-soft prices.
• ICICIBANK gained 7.3%, but open positions fell 8.5%, so part of the move was short covering.
• HDFCBANK fell 5.9% with positions slightly lower but a high 94.2% rollover. Traders are holding on, not exiting.

Our view: Banks are where conviction sits going into November. 

Metals: shorts are being carried forward

Metals had one of the highest rollovers (93.2%) while the sector fell 7.4%. High rollover in a falling sector usually means traders are carrying their short bets into the next month.

• HINDALCO fell 6.7% while open positions jumped 20.4% and rollover rose to 94.8% (from 90.9%). This is a short build-up: new selling alongside falling prices.
• SAIL fell 5.8% with a very high 98.5% rollover.
• APLAPOLLO is the lone bright spot, up 1.2% with positions up 17.8% and 98.1% rollover.

Our view: Stay cautious on metals until prices stabilise. APLAPOLLO is the only name showing buying interest.

Realty: positions held, direction pending

Realty had the highest sector rollover in October at 94.3%, even though prices dipped 1.7%. Traders are staying in, not running.

• INDHOTEL rose 13.8%, but positions fell 31.3%, so this was largely short covering.

Our view: On watch. High rollover sets up a move; we want price to confirm the direction first.

Where shorts are building

Several stocks fell sharply while traders added fresh short positions, a pattern worth avoiding:

Stocks to watch for November

Bottom line

October was a month of cutting exposure, not adding it. Stock futures positions are at a seven-month low and the hedge ratio is back above 12x. The market's leadership is narrow: IT on short covering and banks on steady conviction.

That is not a signal to turn bearish. NIFTY held flat and bank traders are clearly committed. It is a signal to be picky:

• Favour stocks with confirmed fresh buying: PERSISTENT, UNIONBANK, and PSU banks broadly.
• Wait on rallies driven by short covering (TCS and much of IT) until new buyers appear.
• Avoid stocks where shorts are building: HINDALCO, TIINDIA, MFSL, HYUNDAI, MAXHEALTH, DMART.

Index view

NIFTY

Our view: range-bound, with a slight positive tilt. Put support has improved and the index held at 22,700 for two expiries in a row. With futures positions falling, a strong breakout needs fresh buyers to show up first. We believe the first half may be Negative but if it holds 22,180-200, the index has the potential to see some turnaround in the November series. A breach of 22,180 would bring further Negativity.

BANKNIFTY

Our view: building a base, constructive above support. Prices are weak but traders are holding, which often comes before a recovery. Stock-level buying supports this, led by UNIONBANK and PNB, with strong rollover in AXISBANK and SBIN. This is the index we would favour for November.

BANKNIFTY is at its 4-month low, so 53,000 is the key line. If it holds, the high rollover argues for a move back towards 55,300. Breaking above 55,300 would confirm the recovery.
