US stock futures rose collectively during pre-market trading on Wednesday, amid a clear improvement in investor risk appetite after the United States announced an indefinite extension of the ceasefire with Iran, boosting hopes for more room for negotiations between the two sides.

This positive performance was supported by a temporary easing of geopolitical concerns, as investors interpreted the extension of the truce as a sign of a possible de-escalation of tensions, which was directly reflected in market trends towards high-risk assets, especially US stocks.

In trading details, Dow Jones Industrial Average futures rose 0.40%, or about 195 points, to reach 49,534 points, supported by gains in a number of defensive and consumer sectors.

Standard & Poor's 500 futures contracts also rose by nearly 0.50% to reach 7,135.50 points.

Meanwhile, shares of major companies continued to support the upward trend as investors' expectations improved regarding the stability of geopolitical conditions.

The Nasdaq 100 futures index rose 0.68%, or 181.75 points, to trade near 26,816.50 points, driven by a return of momentum to technology and growth-related stocks.
