Stock Market Outlook Today, 18 May 2026: Sensex, Nifty Likely to Stay Cautious; Pharma Stocks in Focus

Indian stock markets are expected to open the week on a cautious note on Monday, May 18, 2026, after benchmark indices ended lower on Friday amid profit booking, rising crude oil prices, persistent weakness in the Indian rupee and continued uncertainty over global geopolitical developments.

Stock Market Outlook Today, 18 May 2026: Sensex, Nifty Prediction for Monday

The BSE Sensex declined 160.73 points, or 0.21%, to close at 75,237.99 on May 15. The NSE Nifty 50 fell 46.10 points, or 0.19%, to settle at 23,643.50. 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.

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.

"Indian equities are expected to trade in a broader range in the near term, as elevated crude oil prices, persistent rupee weakness, and continued volatility in foreign flows keep overall market sentiment cautious," said Siddhartha Khemka, Head of Research, Motilal Oswal Financial Services.

Khemka also said that pharmaceutical stocks could continue to attract investor interest due to their defensive earnings profile and export advantages.

"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," Khemka added.

Nifty Prediction Today, May 18, 2026; Check Technical Outlook

According to Bajaj Broking, the technical structure of the Nifty has weakened after the index broke below the support zone of 23,800, which had held for the previous three weeks.

Nifty formed a bearish candlestick pattern on the weekly chart, characterised by a lower high and a lower low, indicating a corrective bias. Analysts believe that unless the index reclaims the 23,800-24,000 range, the downside pressure may continue.

"Going ahead, in the coming week failure to move above the breakdown area of 23,800-24,000, will keep the bias corrective and can lead to testing of the support area of 23,200-23,000. While a move above the breakdown area will signal pause in the downtrend and open pullback towards 24,500-24,600 levels being the high of April 2026."

"Volatility is expected to remain high with Key focus on the developments around US-Iran tensions, oil-price trajectories and quarterly corporate earnings. Nifty has key support at 23,200-23,000 being the confluence of the lower band of the 8th April bullish gap area and the 61.8% retracement of the previous pullback (22,182-24,601)," Bajaj Broking Research said.

Bank Nifty Outlook Today for Monday

The outlook for Bank Nifty also remains weak. The banking index formed a bearish candlestick pattern and closed below the lower end of its recent consolidation range, signalling continued corrective momentum.

According to Bajaj Broking Research, "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). On the higher side a move above the breakdown area of 54,400-54,600 will signal resumption of up move and will open further upside towards 56,000-56,500."
