Summary
India's benchmark S&P BSE SENSEX declined 135 points (0.18%) to close at 75,183.36 on Thursday, May 21, 2026, marking a modest session loss despite significant intraday volatility. The index opened higher at 75,732.42 and reached an intraday peak of 75,945.79 before reversing course to touch a session low of 74,996.78—a near-1,000-point intraday range. The final close at 75,183.36 represented a marginal decline from Wednesday's close of 75,318.39, continuing a pattern of range-bound trading that has characterized Indian equities throughout mid-May 2026.
The technology and IT services sector bore the primary weight of selling pressure throughout the session. Tech Mahindra fell 1.32% as the largest individual decliner among SENSEX constituents, while Infosys dropped 1.3% and Reliance Industries declined 0.7%. These declines reflect a convergence of factors: persistent concerns about global IT services demand visibility and a spillover effect from Nvidia's recent mixed forward guidance that has pressured technology stocks broadly across global markets. India's IT services companies, which represent defining constituents of both the SENSEX and the broader NSE Nifty 50 index, have been operating in a challenging demand environment extending throughout 2026.
Bajaj Finance also contributed meaningfully to the index's losses, with the financial services stock declining as investor concerns about valuations persisted. The stock's weakness emerged as a secondary headwind alongside the technology sector's underperformance.
Additional volatility was generated by the weekly expiry of SENSEX derivatives on Thursday. Options market activity and position adjustments by traders amplified downward momentum as the session progressed, with selling intensity increasing through the afternoon before the final close. The Nifty 50 traded near flat at 23,654, substantially outperforming the SENSEX's decline and reflecting differential sector composition between India's two primary benchmarks.
Market participants have maintained cautious positioning around the 75,000 level, which has functioned as both support and a focus point for tactical trading throughout May 2026.
