Bharti Airtel fell 3% after a ₹9,300 crore block deal by promoter Indian Continent Investment. SEBI-registered analyst Varunkumar Patel sees short-term weakness, with key support at ₹1,808 and resistance at ₹1,900-1,943. RSI near oversold suggests a possible bounce, but a break below ₹1,857 could drag shares toward ₹1,785.
