The Nifty Bank was the key contributor in the Nifty exhibiting sluggish moves on expiry day, but unlike the Nifty, the banking index continued to trade in a broad range. Despite a 500-point fall from the day’s high, the index managed to hold on to the 55,000 mark on a closing basis, something the bulls could take heart from. Tuesday’s high of 55,536 will be the first level to watch on the upside.
