US equity futures showed gains during European trading hours on Tuesday, buoyed by a reduction in Middle East geopolitical tensions. According to FX Street, Dow Jones futures increased by 0.17%, trading around 53,430, while S&P 500 futures rose 0.23% to approximately 7,650.

The Nasdaq 100 futures led the gains with a 0.68% advance, reaching near 29,090, reflecting growing investor confidence amid the easing concerns. These movements suggest a positive tone for US markets ahead of the regular session.

For Japanese investors, these developments are particularly relevant as shifts in US equity futures can influence risk sentiment and impact foreign exchange and equity flows in Asia.
