Indian equity markets settled lower on Tuesday, September 15, with the BSE Sensex and NSE Nifty50 extending their September decline to well over 3% so far this month. At close, the BSE Sensex was at 74,003.82, down 777.94 points or 1.04%, while the NSE Nifty50 stood at 23,118.60, down 279.50 points or 1.04%.

From a technical perspective, the Nifty50 has reached the swing-low support of June 11, 2026. Both daily and hourly charts are in the oversold zone, indicating that a technical bounce cannot be ruled out from current levels, said Vatsal Bhuva, technical analyst at LKP Securities.

Bhuva said the Nifty has support at 23,000, while resistance has shifted to 23,350-23,500. A decisive close below 23,000 could extend the decline towards 22,500-22,600, near the weekly 200-SMA.
