Trading across Indian equity benchmarks began on a divergent note on Monday, 21 September 2026, as headline indices moved in opposing directions at the opening bell. The BSE Sensex advanced by 240.22 points, or 0.32 percent, to trade at 74,535.18 points in early morning deals. In contrast, the National Stock Exchange benchmark Nifty 50 recorded modest opening weakness, shedding 16.20 points, or 0.07 percent, to commence trading at 23,330.20 points. This opening pattern reversed the preceding Friday dynamic, when the Sensex had closed marginally lower while the Nifty managed a positive close.
Market Breadth Shows Broad Underlying Support
Despite the slight drag on the Nifty headline number, underlying market breadth remained predominantly positive across both exchanges. Within the 30-share BSE Sensex, 24 constituent stocks initiated Monday trading in the green, with only 6 components opening in the red. Across the broader 50-stock Nifty basket, 31 companies opened with price advances, 18 faced downward price pressure, and 1 counter remained completely unchanged relative to its prior closing level.
Cement, Consumer, and Banking Lead Gainers
Cement heavyweight UltraTech Cement emerged as the top gainer among Sensex constituents, advancing by 3.27 percent at the open. It was closely followed by Asian Paints, which gained 2.19 percent to post strong initial performance. Travel and lifestyle counters also saw robust bids, with airline operator IndiGo climbing 1.46 percent, watchmaker Titan advancing 1.41 percent, and retail major Trent moving higher by 1.38 percent. Infrastructure major L&T added 1.12 percent to its stock value.
Financial institutions supported the benchmark push across both private and public lending spaces. ICICI Bank opened higher by 1.07 percent, alongside Kotak Mahindra Bank rising 1.01 percent, Axis Bank gaining 0.68 percent, State Bank of India (SBI) picking up 0.36 percent, and HDFC Bank gaining 0.33 percent.

Selling Pressure Hits Telecom, IT, and Utilities
On the declining side of the board, telecom and major technology software firms exerted downward drag, keeping the Nifty from participating in the morning rally. Leading telecom provider Bharti Airtel recorded the steepest decline among Sensex components, falling 1.07 percent at the opening tick. Infrastructure conglomerate counter Adani Ports also lost ground, dropping 0.99 percent.
Large-cap information technology firms started the week under selling pressure. Infosys fell 0.81 percent, software exporter TCS declined 0.43 percent, and Tech Mahindra slipped by 0.11 percent. Utility major Power Grid recorded a decline of 0.74 percent, completing the cluster of blue-chip counters that opened in the red.
