U.S. stock futures rose Tuesday, with sentiment boosted by President Donald Trump’s announcement of a ceasefire in hostilities between Israel and Iran.

By 06:33 ET (10:33 GMT), the Dow Jones Futures traded 294 points, or 0.7%, higher, S&P 500 Futures gained 49 points, or 0.8%, and Nasdaq 100 Futures advanced 225 points, or 1.0%.

The main averages on Wall Street ended the prior session in the green, all registering gains of around 1%, boosted by hopes that U.S. involvement in the days-long Israel-Iran air war would remain relatively contained. 

Ceasefire optimism boosts Wall Street
Investors have been boosted by Trump declaring earlier Tuesday, via social media, that the ceasefire between Israel and Iran is now "in effect," adding that neither side should violate it.

The statement has lifted expectations that the 12-day bout of fighting that included deadly air strikes has now come to an end.

However, Trump’s comments suggested that the ceasefire would take place in stages, with operations already underway being allowed to finish. 

Still, questions surrounded the longevity of the ceasefire, with the Israeli military already warning that it has identified missiles launched from Iran towards Israel and was ready to retaliate.
