Indian equity benchmark -- Nifty -- ended significantly lower on Tuesday amid renewed concerns over Donald Trump’s tariff imposition. Index made a gap-down start following broadly negative cues from other Asian markets. Soon, index intensified its losses and continued its trade in red. Market participants remained cautious amid reports that Trump’s administration officially issued a notice regarding the imposition of an additional 25 per cent tariffs on Indian imports, with the punitive duties set to kick in on August 27, 2025. Further, continued foreign fund outflow dampened investors’ sentiments. Foreign Institutional Investors (FIIs) offloaded equities worth Rs 2,466.24 crore on Monday, as per exchange data. In afternoon session, index continued its lacklustre trade in red for most part of the session. Sentiments remained weak amid data released by Reserve Bank of India (RBI) indicated a leisurely growth pace in sales of listed private non-financial companies (NFC) at 5.5 per cent in first quarter of 2025-26 compared to 6.9 per cent in the year-ago period. In last leg of the trade, index extended its losses and closed below 24,750 mark.

Most of the sectorial indices ended in red except FMCG stocks. The top gainers from the F&O segment were Britannia Industries, Eicher Motors and Hindustan Unilever. On the other hand, the top losers were HDFC Bank, Vodafone Idea and Vedanta. In the index option segment, maximum OI continues to be seen in the 24900 - 25100 calls and 23900 - 24100 puts indicating this is the trading range expectation.
