US stock markets opened in positive territory on Tuesday, marking a decisive shift in sentiment after several days of declines.
The rebound was driven by reports of a temporary pause in attacks between the United States and Iran, a move intended to create space for ongoing peace negotiations.
The three leading American indices all traded higher shortly after the opening bell, reflecting a rapid repricing of geopolitical risk.
Investors appear to be interpreting the ceasefire pause as a credible step toward de-escalation, allowing capital to flow back into risk assets that had been under pressure from uncertainty surrounding the conflict.
This development follows a similar sentiment shift on Monday, when markets also opened higher on news of a diplomatic breakthrough between Washington and Tehran.
The current rally suggests that the market is not just reacting to a single headline, but is beginning to price in a sustained period of reduced geopolitical tension.
