On April 21, 2026, the Indian stock market is set for a positive opening, with the Nifty 50 index expected to start around 24,400. The previous day saw the Nifty close at 24,364, buoyed by strong Q4 earnings from major banks like HDFC Bank and ICICI Bank, which reinforced confidence in the financial sector. However, a sell-off late in the session reflected concerns over global factors, particularly geopolitical tensions related to the US-Iran ceasefire. The Bank Nifty index also ended slightly higher at 56,582. Global markets presented a mixed picture, with US markets closing lower amid renewed tensions, while Asian markets, including Japan's Nikkei, showed resilience. The India VIX, currently around 18.7, suggests heightened volatility, particularly with the weekly expiry approaching. Analysts recommend a buy-on-dips strategy, with key support levels identified for both Nifty and Bank Nifty. Additionally, eight stocks have been highlighted for intraday trading, including CG Power and JK Cement, with specific buy targets and stop-loss levels provided.
