How to trade TCS shares before Q1 results? Key levels and 5 things to watch out for

TCS shares have corrected around 35 percent year-to-date against a 9 percent fall in the Sensex, underperforming peers Wipro and HCL Tech. Brokerages expect flat to marginal constant-currency revenue growth for Q1, with EBIT margins likely declining 100-160 basis points sequentially due to wage hikes. Key support lies at the 1,985-2,000 zone, with resistance at 2,120 and 2,250, as investors watch for deal wins, BFSI demand commentary, and the impact of AI on pricing.
