Around 1:50 pm, the Sensex was up 75.95 points at 74,059.13, while the Nifty hovered near flat at 23,217.90.The recovery faded later in the day as selling resumed.Global and domestic pressure pointsMarket sentiment remained under pressure from elevated crude oil prices and renewed geopolitical tensions in the Middle East. Persistent foreign institutional investor (FII) outflows and a weaker rupee also added to caution.Ajit Mishra, SVP-research at Religare Broking Limited, was quoted by news agency ANI as saying that markets remained volatile on the weekly expiry day and ended lower amid weak global cues.He added that sentiment was fragile due to geopolitical escalation and concerns over elevated global interest rates after stronger US inflation data.Sectoral trendsIT stocks were the worst hit, with the Nifty IT index falling over 1%, followed by declines in FMCG, energy, realty, PSU banks, consumer durables and chemicals.Banking and pharmaceutical stocks showed resilience and helped limit broader losses, while Nifty Media bucked the trend, ending 1.78% higher at 1,465.50.Analysts noted that the market continues to see selling on rallies, though selective buying in heavyweight stocks is providing support.Mishra cautioned that a decisive fall below the 23,000 level on the Nifty could trigger further correction, while upside momentum may remain capped near 23,500.
