The Indian stock market is anticipated to open lower on April 23 due to rising crude oil prices, which may dampen investor sentiment. The Nifty 50 index closed at 24,378.10, down 198.50 points, while the Sensex dropped 756.84 points to finish at 78,516.49. Analysts indicate that the Sensex may face continued weakness unless it surpasses the 79,000 mark, with potential declines to 78,200 or 78,000. For the Nifty 50, significant resistance is noted around 24,400 - 24,500, while immediate support is expected in the 24,100 - 24,150 range. The Bank Nifty, however, has shown resilience, closing above its 100-day and 200-day exponential moving averages for the second consecutive session, indicating a potential upward trend if it breaks through the 57,500 - 57,600 resistance zone. Market volatility remains high due to geopolitical tensions and fluctuating crude oil prices.
