F&O Prediction for Tomorrow 20 May 2026: PCR 0.94, 21 May Expiry in 2 Days and FOMC Minutes Tonight

Posted by: Ankit Jaiswal, Senior Research Analyst, Univest | 19 May 2026

The F&O prediction for tomorrow on 20 May 2026 is shaped by the most compressed event-risk calendar of May 2026: the Nifty 50 weekly options series expires on Thursday 21 May, just 2 trading sessions away, while the FOMC minutes release tonight will create significant gap risk for Thursday’s opening via GIFT Nifty. The Nifty 50 closed at 23,618 on Tuesday with India VIX falling 4.87 per cent to 18.68, the PCR recovering to 0.9435 (Upstox live data), and the 21 May weekly series showing call writing concentrated at the 23,500 and 23,600 strikes while put writing is anchored at 23,400 and 23,300, per Choice India confirmed data.

Ankit Jaiswal, Senior Research Analyst at Univest, notes that the F&O prediction for tomorrow operates in a classic near-expiry high-theta environment where small Nifty moves create disproportionate option P&L changes. With ATM IV at approximately 18.5 to 19 per cent (derived from VIX 18.68) and just 2 days to the 21 May Thursday expiry, theta decay is at maximum velocity. Kunal Singla, Associate Director at Univest, adds that the F&O prediction for tomorrow’s base case is range compression between 23,400 and 23,700, with option writers defending both sides and Max Pain at approximately 23,500 acting as the gravitational centre for Wednesday’s session.

F&O Dashboard: 19 May 2026 Close

Nifty F&O Prediction for Tomorrow: 21 May Expiry Analysis

21 May Expiry: Thursday, 2 sessions away; maximum theta decay phase

Nifty Max Pain (21 May): ~23,500

Call Wall: 23,600 CE (heaviest call writing per Choice India)

Put Wall: 23,300-23,400 PE (put writing support)

Expected Range Wednesday: 23,400 to 23,750

The most important insight in Ankit Jaiswal’s F&O prediction for tomorrow is that the 21 May expiry is just 2 days away and Nifty at 23,618 is 118 points ABOVE the estimated Max Pain of 23,500. This means option writers are incentivised to push the index lower toward 23,500 through Wednesday and into Thursday’s expiry close. The F&O prediction for tomorrow therefore expects selling pressure on any intraday rally above 23,700 as call writers defend the 23,600 strike.

Kunal Singla’s F&O prediction for tomorrow on the PCR of 0.9435 confirms a near-neutral to mildly bullish options market. A PCR of 0.9435 means put open interest is only slightly below call open interest, indicating balanced positioning without extreme fear or greed. This neutral PCR combined with a falling VIX of 18.68 makes the F&O prediction for tomorrow supportive of option-selling strategies rather than directional long options buying.

Bank Nifty F&O Prediction for Tomorrow

Bank Nifty Close: ~53,696 (+0.30%)

BN Weekly Expiry: 25 May (Monday, 6 days)

Estimated BN Max Pain: ~53,200-53,500

Key BN Resistance: 54,000 CE (call writing)

Key BN Support: 52,500-52,800 PE (put writing)

The Bank Nifty F&O prediction for tomorrow is mildly positive after Tuesday’s 0.30 per cent recovery, led by private banks (Kotak +1.14%, Federal +0.80%, ICICI +0.58%) while PSU banks remained under pressure. Kunal Singla’s F&O prediction for tomorrow on Bank Nifty identifies the 53,800 level as the pivot: above 53,800 with private bank leadership shifts the Bank Nifty F&O prediction for tomorrow to mildly bullish; below 53,400 confirms the PSU bank drag and targets 52,800 support.

F&O Strategies for Tomorrow 20 May 2026

Near-Expiry: Short Straddle at 23,500 (21 May Expiry)

With 2 days to the 21 May expiry and ATM IV at 18.5 to 19 per cent, selling the 23,500 straddle (23,500 CE + 23,500 PE) for Thursday expiry is Jaiswal’s preferred F&O prediction for tomorrow premium collection strategy. Maximum profit if Nifty closes between 23,200 and 23,800 on Thursday. Exit if Nifty moves more than 300 points from 23,500 in either direction intraday.

Bank Nifty: Long Private Bank Spread

For Bank Nifty, Kunal Singla’s F&O prediction for tomorrow favours a bull call spread (buy 53,700 CE, sell 54,200 CE for 25 May expiry) to express the private bank relative strength view with defined risk. This aligns with the established Kotak-ICICI-Federal Bank leadership pattern.

Pre-FOMC Rule: Close All Overnight by 3:20 PM IST

The non-negotiable rule in the F&O prediction for tomorrow: close all overnight Nifty futures and options positions by 3:20 PM IST Wednesday. FOMC minutes will create a GIFT Nifty gap for Thursday’s 21 May expiry day. Holding overnight in near-expiry options through a FOMC gap is the highest risk action in the F&O prediction for tomorrow context.

Risks to F&O Prediction for Tomorrow

• FOMC Gap on Thursday 21 May Expiry: FOMC minutes tonight create a GIFT Nifty gap for Thursday, which is the 21 May weekly expiry day. A 200-plus point gap up or down on expiry day creates gamma explosion in near-ATM strikes, making all short premium strategies extremely dangerous overnight in the F&O prediction for tomorrow.
• PCR Extreme Reading Risk: PCR at 0.9435 is near-neutral. If Wednesday sees heavy put buying (PCR drops to 0.75), it signals institutional fear building and would shift the F&O prediction for tomorrow to bearish on Bank Nifty and Nifty.
• PSU Bank Systemic Weakness: SBI -2.53%, Canara -2.47%, PNB -2.20% Tuesday confirms structural PSU bank weakness. Any credit quality news would amplify Bank Nifty futures selling beyond the F&O prediction for tomorrow base case.

Conclusion: F&O Prediction for Tomorrow 20 May 2026
