Investors were assessing September-quarter earnings from HDFC Bank and ICICI Bank, two of the index's biggest constituents, while crude oil prices above $108 a barrel remained a concern for risk sentiment. Hariselvan Radhakrishnan, founder and CEO of HST Wealth, said a positive market reaction to private-bank earnings could help equities absorb higher oil prices. He identified 23,150 as the Nifty's immediate resistance level. The outlook therefore centred on the market's response to bank earnings and the direction of crude prices..Stock market today: Crude prices remain a major driving force for Dalal Street Crude oil prices retreated from the $110-a-barrel level reached on Friday after US President Donald Trump waived sanctions and tariffs on Russia, raising the prospect of additional fuel supplies entering the market.

Despite the pullback, oil prices remained elevated, with continuing security threats in the Middle East and uncertainty surrounding US-Iran negotiations keeping the outlook volatile. The easing in prices followed the US decision to grant a waiver on key sanctions and tariffs imposed under the Graham Act. Secretary of State Marco Rubio said Trump would take up to 60 days to evaluate the economic consequences of the waiver..Stock market recap: Top nine firms added Rs 3.65 lakh crore in market value The combined market valuation of nine of India's 10 most valued companies rose by Rs 3.65 lakh crore over the previous week, reflecting the bullish trend in equities.
