Indian equity markets staged a sharp reversal on Tuesday, with benchmark indices closing significantly lower as broad-based selling pressure swept across sectors.

The BSE Sensex dropped 893 points, or 1.16%, to finish the session at 76,200.

The decline marked a stark contrast to the previous day's modest gains, which had been fueled by improving investor sentiment following reports of progress in US-Iran peace negotiations.

The swift downturn suggests that geopolitical optimism is fragile and that domestic or global risk factors are quickly reasserting control over market direction.

The breadth of the selloff indicates that the weakness was not confined to a single industry but reflected a wider shift in risk appetite.

Traders who had positioned for a continuation of the Monday rally faced immediate mark-to-market losses as the market opened lower and failed to find support.
