Nifty ended a five-week consolidation with strong Friday gains as Q1 earnings from IT majors and select private banks boosted sentiment. SBI Securities’ Sudeep Shah tells ETMarkets that a Bollinger Band squeeze and falling ADX point to a big directional move ahead, with 24,550 the key level to watch as earnings from Reliance, HDFC Bank, ICICI Bank, Axis Bank and Kotak Mahindra Bank roll in over the weekend.
