The Indian benchmark indices opened in green on Tuesday amid positive global cues, as geopolitical tensions eased after Iran–Israel ceasefire announced by US President Donald Trump.

Buying was seen in the auto, IT, PSU bank and financial service sectors in the early trade.

At around 9.31 am, Sensex was trading 756.5 points or 0.92 per cent up at 82,653.33 while the Nifty added 229 point or 0.92 per cent at 25,200.90

According to analysts, the dramatic developments in West Asia culminating in President Trump’s announcement of ceasefire indicate that the worst of the conflict is over.

"The sharp reactions in the crude oil and stock markets suggest the geopolitical situation limping back to normalcy," said Dr. VK Vijayakumar, Chief Investment Strategist, Geojit Investments Limited.

Nifty Bank was up 557.25 points or 0.99 per cent at 56,616.60. The Nifty Midcap 100 index was trading at 58,617.80 after adding 411 points or 0.71 per cent. Nifty Smallcap 100 index was at 18,443.95 after climbing 123.05 points or 0.67 per cent.

"The recent recovery in both Nifty and Bank Nifty indicates strong buying interest at lower levels, but a decisive breakout above key resistance zones—25,200 for Nifty and 56,300 for Bank Nifty—is still required for sustained upside, said Aakash Shah, Technical Research Analyst of Choice Broking

Given the current environment of heightened volatility and uncertainty, investors should remain cautiously optimistic, he added.
