The Sensex and Nifty gained for the fourth straight day, reaching higher figures with intense buying in IT and telecom stocks and foreign fund contributions. The positive Q4 earnings from banks and the Fed's monetary policy in the coming week would be monitored. Analysts predicted that while the Fed may raise interest rates by 25bps, it will most likely pause after that. Notably, the inverted head and shoulder pattern on the daily chart implies a bullish reversal that could lead the Nifty towards 18000/18100 over the near term.
