Jefferies has highlighted Infosys Ltd., Coforge Ltd. and Sagility India Ltd. as its preferred picks in the Indian IT sector, citing a need for bottom-up stock selection, amid weakening revenue trends and rising macro uncertainty.Overall revenue growth for IT firms worsened in the fourth quarter of financial year 2025, with large-cap companies reporting sequential revenue declines, the brokerage noted.This comes as the US and China agreed to reduce tariffs after a month of steep increases. Right after US announced the terms to reduce tariffs on China, the NSE Nifty IT jumped 6.90% to 38,356.10, the highest level since March 5.In terms of valuations, Nifty IT is currently trading at approximately 25 times forward PE—on par with its five-year average and above pre-tariff levels—limiting further upside. The brokerage believes that wide divergence in performance across IT players calls for selective stock-picking.Infosys is favoured for its valuation support and 3.5% dividend yield, which offers downside protection. Coforge is backed by a strong order book that supports earnings visibility and justifies its premium valuation. Sagility is also viewed positively for its growth outlook. On the contrary, Jefferies remains cautious on Wipro and Tech Mahindra due to earnings risks and potential valuation derating.US-China, US-UK Trade Deals Boost Indian IT Outlook; Infosys, TCS, Persistent Among Top Analysts' PicksJefferies' coverage universe posted a 1.5% quarter-on-quarter constant currency decline in organic revenues.
