Indian stock markets are likely to remain volatile and trade with a cautious to negative bias in the week of May 18 to May 22, 2026, after benchmark indices suffered a sharp correction amid rising geopolitical tensions, elevated crude oil prices, persistent foreign fund outflows and continued weakness in the Indian rupee. According to Master Capital Services Ltd, the Nifty 50 tumbled to a five-week low before closing at 23,643.50, down 2.20% on a weekly basis, while the BSE Sensex declined 2.70% to settle at 75,237. The weakness was even more pronounced in the broader market, where mid-cap and small-cap stocks came under significant pressure - the Nifty Midcap index fell 2.20%, while the Nifty Smallcap index plunged 4.56%, reflecting widespread profit-booking and a sharp reduction in investor appetite for risk. As per SBI Securities, immediate support for Nifty is placed between 23,500-23,450 zone, while on the flipside, the immediate resistance for Nifty is placed in the 23,800-23,850 zone. Market participants are likely to remain focused on several key triggers in the coming sessions, including crude oil price movement, developments surrounding US-Iran tensions, the trajectory of the Indian rupee, foreign institutional investor activity and the ongoing March quarter earnings season.
On Friday, the Indian stock market ended lower on profit booking, with the Nifty 50 closing below 23,650 level at 23,643.50, down 46.10 points or 0.19%, and the Sensex declining 160.73 points, or 0.21%, to settle at 75,237.99. During the session, the Nifty had touched an intraday high of 23,839.30 before losing momentum in the second half of trade as investors booked profits. The decline was attributed to profit booking activities in the market, with both indices erasing all intraday gains amid late selling pressure. Sectorally, Realty, Information Technology and Automobile stocks were the worst hit - the Nifty Realty index plunged 8.17%, the Nifty IT index declined 5.71% and the Nifty Auto index fell 4.36%. In contrast, defensive and commodity-linked sectors offered some resilience - the Nifty Pharma index rose 2.18%, the Nifty Healthcare index gained 2.17% and the Nifty Metal index advanced 1.91%. According to SBI Securities, despite the pullback over the last three sessions, the index continues to trade below its key moving averages, reflecting underlying weakness.
Sensex formed a bearish candle on weekly charts, and is currently trading comfortably below short-term moving averages, which is largely negative. According to Amol Athawale, VP Technical Research at Kotak Securities, quoted by Livemint, "We are of the view that the short-term market outlook remains weak, but a pullback is likely to continue if Sensex manages to trade above 75,000. On the higher side, the 50-day SMA at 75,800 will be a key level to watch. A move above 75,800 could lead to a test of the 20-day SMA or 77,000 – 77,300." On the downside, he believes a fresh sell-off is possible only if Sensex breaks below 75,000, potentially dragging the index down to 74,500. As per Master Capital Services Ltd, the Bank Nifty declined approximately 2.89% and slipped below all major short-term and long-term moving averages, including the 21-day, 55-day, 100-day and 200-day exponential moving averages, indicating that momentum has shifted decisively in favour of the bears. According to SBI Securities, immediate support for Bank Nifty is placed in the 53,300-53,200 zone, while immediate resistance is placed in the 54,100-54,200 zone.
Nifty 50 index formed a small-bodied candle on the daily chart with a noticeable upper wick, indicating selling pressure at higher levels. As reported by Livemint, for the week, the index declined 2.20% and formed a bearish candlestick pattern on the weekly chart with a lower high and a lower low and a long lower shadow. Nagaraj Shetti, Senior Technical Research Analyst at HDFC Securities, noted that the underlying trend of Nifty 50 remains choppy, and the index is expected to oscillate within a broader high low range of 23,800 - 23,200 levels for this week. Mayank Jain from Share.Market by PhonePe Wealth highlighted that the 23,250 level is now the immediate line of defense, and if Nifty 50 breaks 23,250 on a closing basis, it opens the door for a deeper correction toward 23,000. According to SBI Securities, immediate support for Nifty is placed between 23,500-23,450 zone, while on the flipside, the immediate resistance for Nifty is placed in the 23,800-23,850 zone. As per Master Capital Services Ltd, "Technically, the index has once again tested the recent breakdown zone, indicating that bears continue to maintain control at higher levels. As long as Nifty trades below the crucial 23,850 resistance mark, the overall setup favors a 'Sell on rise' approach for the coming sessions."
Bank Nifty index ended the week on a highly bearish note, plunging roughly 2.89% and declining below all major short-term and long-term moving averages, including the 21-day, 55-day, 100-day and 200-day exponential moving averages, as per Master Capital Services Ltd. This technical development indicates that momentum has shifted decisively in favour of the bears. According to Bajaj Broking Research, "The bias continues to remain down below last week breakdown area of 54,400-54,600 and a follow through weakness will open further downside towards 52,700-52,400 levels being the confluence of the lower band of the 8th April gap area and the 61.8% retracement of the previous pullback (49,955-57,456)." For the coming week, immediate resistance is placed at the 54,100-54,200 level, as long as prices continue to trade below this crucial zone, the overall market sentiment remains under intense pressure. On the downside, immediate support is placed at 53,100, with a decisive slide below this floor being critical as it may trigger a sharper correction.
Pharmaceutical stocks are expected to remain in focus going forward, supported by persistent rupee weakness, improving export competitiveness, and continued strength in domestic healthcare demand. According to Motilal Oswal Financial Services, "Pharmaceutical stocks are expected to remain in focus going forward, supported by persistent rupee weakness, improving export competitiveness, and continued strength in domestic healthcare demand. The sector is also likely to benefit from its relatively defensive earnings profile amid ongoing global macro uncertainty and rising volatility across broader markets." US President Donald Trump issued a fresh warning to Iran, raising concerns about a possible escalation in Middle East tension and its impact on global oil supplies. In a post on Truth Social, Trump said Iran should "get moving, Fast," and warned that "the Clock is Ticking." He further added that "there 'won't be anything left' if action was not taken soon and said, 'Time is of the essence!'." Oil prices moved higher in early trade, with Brent crude rising 1.34% to $110.72 per barrel and US West Texas Intermediate crude climbing 1.75% to $107.26 per barrel. Dr. VK Vijayakumar, Chief Investment Strategist at Geojit Investments, noted that "Brent crude has spiked to $111 on absence of initiatives to open the Strait of Hormuz. Elevated crude may force another round of price hikes in petrol and diesel, which will have negative implications for inflation." The Indian rupee hit a record closing low of 95.86 against the US dollar on Friday, May 15, after briefly slipping below the 96 per dollar mark during the trading session, with so far in 2026, the rupee having weakened more than 6% against the U.S. dollar. The yield on the U.S. 10-year Treasury note climbed to 4.603%, its highest level since late May 2025, making emerging market assets such as Indian equities relatively less attractive to foreign investors.
