BSE Sensex climbed as much as 368 points or 0.48% to an intraday high of 75,683 on Tuesday, 19 May, while the Nifty50 advanced 110 points or 0.45% to 23,758 in early trade. The rally was driven by hopes of a de-escalation in the West Asia conflict after US President Donald Trump signalled a possible nuclear deal with Iran, easing fears around energy supply disruptions.

IT Stocks Lead the Charge

Technology shares emerged as the session's standout performers. The Nifty IT index surged 4%, while the Nifty MidSmall IT & Telecom index advanced nearly 3%. The Nifty Chemicals index also gained 1.16%. Analysts attributed part of the IT rally to a rotation trade — concerns over elevated valuations in global AI-linked stocks are reportedly prompting investors to seek relatively attractive segments within India.

Laggards and Key Decliners

Hindalco Industries declined the most among Nifty constituents, falling over 1%, followed by Coal India down 0.93% and ONGC lower by 0.81%. Titan Company shed around 0.6%, while Kotak Mahindra Bank and Eternal slipped 0.54% and 0.49%, respectively. JSW Steel, UltraTech Cement, and Shriram Finance were also trading lower by up to 0.47%. Heavyweights HDFC Bank and ICICI Bank slipped marginally. The Nifty Private Bank index dipped 0.11%, with Nifty Auto and Nifty Metal also trading in the red.

The Iran Factor and Oil Prices

Markets found a key support pillar after President Trump said he had paused a planned strike on Iran following a peace proposal from Tehran, adding there was a 'very good chance' of reaching a deal on Iran's nuclear programme. The development sent oil prices lower: international benchmark Brent crude fell 2.74% to $109.02 per barrel, while US WTI crude declined 2.16% to $102.12 per barrel. Lower crude is a meaningful tailwind for India, a major oil importer, easing both inflation and the current account deficit.

Broader Macro Concerns Persist

Despite the session's gains, analysts cautioned that headwinds around growth, inflation, and currency depreciation remain, compounded by the ongoing energy crisis. They advised investors to favour sectors relatively insulated from these pressures — including pharmaceuticals, power-related companies, and defence stocks. On corporate earnings, analysts noted that Q4 results were broadly encouraging and, in many cases, better than expected, suggesting the economy had begun recovering on the back of last year's fiscal and monetary stimulus before the latest energy shock hit. According to market experts, 'a quick resolution of the Strait of Hormuz crisis could help the economy recover faster and limit the extent of the slowdown expected this year.'

Asian and US Market Backdrop

The global picture was mixed. In Asia, Japan's Nikkei and South Korea's KOSPI slipped up to 3%, while Hong Kong's Hang Seng traded marginally higher. Overnight on Wall Street, the S&P 500 ended nearly flat, down 0.07%, while the Nasdaq declined 0.51%. If foreign institutional investor buying gathers momentum, market experts suggest large-cap financials — particularly leading banks — are positioned to outperform, given their reasonable valuations and growth potential.
