Nifty to gain upside momentum above 25,500; MphasiS, OFSS see short buildup

On Wednesday, the Nifty hit a fresh all-time high at 25,482, but retreated and closed in red at 25,378. The Nifty September futures dipped 0.2 per cent, as the premium declined to 18 points from 31 points and the open interest (OI) decreased by 3.4 per cent or 18,808 contracts mainly on account of unwinding of short positions by retail investors.

Technically, the Nifty formed a spinning top candle on a daily scale near its all-time high, signalling some short-term hesitation, said Hrishikesh Yedve, AVP Technical and Derivatives Research at Asit C. Mehta Investment Interrmediates in a note.

Therefore, on the upside, 25,500 will act as an immediate hurdle for Nifty. If the index sustains above 25,500, it could test the 25,600 levels. On the downside, 25,280 – 25,300 serves as immediate support base for Nifty followed by 21-DEMA support, which is placed near 25,080 levels, the analyst added.

In contrast, the Bank Nifty which was the key outperformer yesterday, the futures ended 0.9 per cent higher. However, the premium shrunk to mere 7 points from 107 points, and the OI declined by 5 per cent.

The Bank Nifty formed a strong bullish candle on a daily scale, indicating strength. However, it will encounter short-term resistance near the psychological level of 53,000. If Bank Nifty sustains above this level, the rally could extend toward 53,500 – 53,800, Hrishikesh Yedve said.

If Nifty fails to sustain above 25,250, the next monthly support level is placed only at 24,750, said Sahaj Agarwal, Senior Vice President, Head of Derivatives Research at Kotak Securities in a note.

The Nifty options data reflects a neutral stance, with balanced call and put writing. Traders seem to be awaiting a decisive move beyond 25,550 or below 25,300, said Dhupesh Dhameja, Technical Analyst at SAMCO Securities in a note.

Significant open interest is observed at the 25,000 Put (71.84 lakh contracts) and 26,000 Call (1.05 crore contracts), reflecting a ‘buy on dips’ sentiment. Put writers are defending lower levels, while call writers have adjusted to higher strikes.’

The Put-Call Ratio (PCR) dropped to 0.90 from 0.98, indicating a shift from bullish to sideways sentiment as both call and put writers balance their positions. Max Pain stands at 25,300, signalling this as a key pivot level for upcoming market moves, Dhupesh highlighted.

In case of Bank Nifty, significant open interest is focused on the 52,800 Call (1.28 crore contracts) and 52,700 Put (97.35 lakh contracts), indicating a tug-of-war between call and put writers, with 52,800 emerging as a key resistance point.
