The BSE Sensex climbed 139 points, or 0.2%, to 84,701 in early trade on Monday, rising for the sixth consecutive session and reaching its highest level since October 27, supported by an improving earnings outlook. Sentiment was also lifted by the clear victory of the BJP-led NDA in the Bihar assembly elections, which boosted expectations of political stability and policy continuity. Almost all sectors traded in the green, including banking and financial services. Auto stocks rose 0.3% despite pressure from Tata Motors, which plunged 4.2% after cutting its margin forecasts. Gains were capped by losses in the IT sector, which slipped 0.3% on declines in TCS (-0.5%) and Infosys (-0.2%). Fading expectations of a US rate cut in December, following hawkish remarks from key Fed policymakers, also weighed on sentiment. Meanwhile, mid-cap and small-cap indices gained 0.6% and 0.7%, respectively. Among the top performers were Kotak Mahindra (1.3%), Axis Bank (1.2%), and Bajaj Finance (1.0%).
