Indian stock markets witnessed a strong rally on Tuesday's opening session after US President Donald Trump announced a ceasefire between Israel and Iran, bringing some relief to global investors amid recent geopolitical tensions.

The benchmark Nifty 50 index opened higher at 25,179.90, gaining 208 points or 0.83 per cent. The Sensex also opened strong at 82,534.61, marking a jump of 637.82 points or 0.78 per cent.

Experts said that with tensions between Israel and Iran de-escalating, investors are now shifting focus to upcoming global events that could influence markets. One of the key dates on investors' radar is July 9, the deadline related to US tariff decisions. If tariff concerns are deferred or resolved, the markets may continue their upward trend.
