Heavy F&O Activity in Telecom and Banks May 2026: What the Options Market Is Saying About Bharti Airtel, SBI and Infosys

F&O stocks in focus in May 2026: Bharti Airtel, SBI, Infosys and Vodafone Idea are seeing record F&O volumes. Weekly expiry days are driving intraday volatility. Here is what the activity signals.

Heavy F&O activity in telecom and banking stocks is the fifth retail momentum theme driving Indian markets in May 2026. Nifty Bank weekly options expire every Thursday, creating systematic volatility spikes in ICICI Bank, SBI, YES Bank and Bajaj Finance. Nifty IT stocks like Infosys and Bharti Airtel are seeing elevated options open interest ahead of earnings-related catalysts. Vodafone Idea, despite being in the SME-adjacent space, is generating record NSE volumes on the turnaround story. Understanding why F&O activity is elevated helps investors separate structural momentum from temporary positioning noise.

Why Bharti Airtel F&O Activity Is Elevated

Bharti Airtel closed at Rs 1,910 on 21 May 2026. The EGM on 12 June 2026, at which the company will consider issuing up to 14.676 crore shares to ICIL at Rs 1,923 per share on a preferential basis, is creating near-term options activity. Institutional investors are positioning around the Rs 1,923 strike, which represents where a large institutional buyer is willing to pay above the current market price. Call writers at the Rs 2,000 strike and put buyers at Rs 1,850 create the bracket within which Airtel F&O volumes are concentrated. The Jio IPO delay also removes a structural overhang, keeping Airtel’s bullish options positioning intact.

SBI and Banking: Weekly Nifty Bank Expiry Mechanics

SBI at Rs 951.70 generates massive F&O volumes every Thursday because of Nifty Bank’s weekly options expiry. SBI is one of the top-10 Nifty Bank index constituents by weight. When Nifty Bank calls near Rs 53,000 to Rs 55,000 strikes expire, option writers in SBI futures mechanically add or remove delta hedges, creating systematic intraday swings. Retail traders should understand that SBI’s Thursday afternoon volatility is largely mechanical (expiry-driven) rather than fundamental. The structural trade in SBI is longer-term: 23 percent discount to 52-week high, PE 10.71 times, FY26 PAT Rs 83,299 crore.

Infosys: F&O Interest Around Dividend Record Date

Infosys closed at Rs 1,181.20 on 21 May 2026. The final dividend of Rs 25 per share with record date 10 June 2026 is creating F&O interest through the dividend arbitrage mechanism: investors who buy Infosys shares before the record date receive the Rs 25 dividend, creating a natural demand signal in the 3 to 4 week window before 10 June. Options traders are using this as a basis for positions around the Rs 1,100 to Rs 1,200 range. FY26 EPS of Rs 71.58 at a PE of 16.50 times is the fundamental anchor at a historically low valuation for Infosys.

• Vodafone Idea F&O: Rs 13.62 | Record NSE volumes on turnaround story | 50-DMA Rs 10.10 | Turnaround momentum play

What Heavy F&O Activity Signals (and What It Does Not)

High F&O open interest and volume in a stock signals institutional positioning, not necessarily direction. It means institutions have placed bets but the direction can be either way. A stock with heavy put buying (Vodafone Idea) can signal scepticism about the turnaround. A stock with heavy call buying (Bharti Airtel near the EGM price) can signal bullish conviction. The safest way to use F&O data is as a volatility indicator: high open interest means the stock will move sharply on the next catalyst. Position sizing accordingly. Consult a SEBI-registered advisor before any F&O trading.

FAQs on F&O Stocks May 2026

Which stocks have the highest F&O activity in May 2026?

Ans. The highest F&O activity in May 2026 is in Bharti Airtel (Rs 1,910, EGM 12 June catalyst), SBI (Rs 951.70, Nifty Bank weekly expiry driver), Infosys (Rs 1,181.20, Rs 25 dividend record date 10 June) and Vodafone Idea (Rs 13.62, turnaround momentum generating record NSE volumes).

Why is there heavy F&O activity in banking stocks every Thursday?

Ans. Every Thursday is the weekly Nifty Bank options expiry. As call and put options near their strike prices at expiry, option writers mechanically hedge by buying or selling Nifty Bank futures and constituent stock futures including SBI, ICICI Bank and YES Bank. This creates systematic Thursday afternoon intraday swings that are largely mechanical rather than driven by fundamental news.
