On May 19, 2025, the BSE Sensex dropped 271.17 points (0.33%) to close at 82,059.42, while the NSE Nifty 50 declined 74.35 points (0.30%) to settle at 24,945.45. The weakness was attributed to global risk-off sentiment and continued selling pressure in large-cap stocks.
As the Sensex weekly expiry approaches on Tuesday, May 20, 2025, the National Stock Exchange (NSE) has imposed a trading ban on 3 stocks in the futures and options (F&O) segment.
The ban was triggered as these securities breached 95% of the market-wide position limit (MWPL). While trading in F&O for these stocks is restricted, they remain available for trading in the cash market.
The stock under the F&O ban for May 20 include:
Hindustan Copper shares gained 1.32%, ending at ₹230.00. The stock opened at ₹224.70 and climbed to an intraday high of ₹231.45, with a low of ₹224.70. The previous close stood at ₹227.00.
The company’s market cap stands at ₹22,241.55 crore (full) and ₹7,527.21 crore (free float). Hindustan Copper trades with a P/E of 54.57, P/B of 9.12, and has a ROE of 16.71%. Itbelongs to the Copper industry segment and is part of the BSE 500 index. Despite recent gains, the stock remains well below its 52-week high of ₹415.60.
Manappuram Finance slipped 2.03% to ₹224.00 in pre-open trades. The stock touched a high of ₹229.95 and a low of ₹228.35, down from its previous close of ₹228.65.
The company holds a market cap of ₹18,960.14 crore (full) and ₹12,159.33 crore (free float). With an EPS (TTM) of ₹21.23 and P/E of 10.77, it operates in the NBFC sector under the BSE 500 index. The 52-week range is ₹138.40 to ₹247.55, indicating it trades near mid-range valuations.
Titagarh Rail remained flat at ₹937.65. It opened at ₹925.50 and traded between ₹974.05 (high) and ₹923.40 (low) during the pre-open session. The previous closing price was also ₹937.65.
The stock is under ASM ST: Stage 1 monitoring. Its 52-week high and low are ₹1,896.50 and ₹655.30 respectively. With a P/E of 40.89 and ROE of 13.01%, the company continues to be a key player in the Railway Wagons industry and is included in the BSE 500 index.
The weekly expiry of Sensex options contracts takes place every Tuesday, with the preceding trading day designated as the expiry if Tuesday is a trading holiday.
Contracts are settled at the normal market closing time on the expiry day or later, as determined by the exchange.
If the last Tuesday of the expiry period is a trading holiday, the expiry for individual securities shifts to the previous trading day.
Interestingly, in the MarketWatch display, the expiry date for last week’s contracts is not shown, as these are treated as monthly contracts. Instead, only the month’s name and the strike price are displayed.
As Indian equity benchmarks continue to face pressure amid global uncertainties, the Sensex weekly expiry adds another layer of market sensitivity. The presence of Hindustan Copper, Manappuram Finance, and Titagarh Rail Systems on the F&O ban list for May 20 underscores heightened speculative activity and elevated open interest in these counters. Traders should remain cautious and closely monitor these stocks, as expiry-day volatility and F&O restrictions may influence price action.
