On May 18, the Indian stock market is anticipated to open lower, influenced by global market trends and rising crude oil prices linked to the escalating conflict between the US and Iran. The Sensex, which closed at 75,237.99, is under pressure, having formed a bearish candle on the weekly charts. Analysts from Kotak Securities highlight that if the Sensex can maintain above 75,000, it may experience a pullback, with 75,800 as a crucial resistance level. Conversely, a drop below 75,000 could lead to further declines towards 74,500 or even 74,000. The Nifty 50 index also shows signs of weakness, closing at 23,643.50, and is expected to oscillate between 23,800 and 23,200 this week. A critical support level is identified at 23,250, below which a deeper correction could ensue, targeting 23,000. The Bank Nifty index ended lower at 53,710.35, with significant support at 53,200 and resistance around 54,400. Overall, market sentiment remains bearish as key indices struggle against selling pressures and technical indicators.
