Major indexes on the New York stock market began the session higher on the 8th (local time), lifted by a rebound in leading semiconductor manufacturers' shares as Middle East tensions eased.
As of 9:45 a.m., on the New York Stock Exchange (NYSE), the Dow Jones Industrial Average was up 151.29 points, or 0.30%, from the previous session to 51,018.07.
The Standard & Poor's (S&P) 500 rose 55.84 points, or 0.76%, to 7,439.58 in the same period, and the tech-heavy Nasdaq composite started the session up 311.93 points, or 1.21%, to 26,521.36.
Gains in these indexes were influenced by a rebound in shares of major semiconductor corporations last week as the Middle East entered a phase of easing tensions.
Iran and Israel, which exchanged ballistic missiles over the weekend, each said they were halting military operations, and U.S. President Donald Trump also said "both sides are seeking an immediate cease-fire."
Also, with bargain-hunting under way, the Philadelphia semiconductor index is up 3.89%, and shares of key chipmakers are rebounding.
However, with Middle East tensions still ongoing, some analysts note that prolonged inflation from elevated oil prices is acting as a risk to the stock market.
Callie Cox, chief market strategist at Ritholtz Wealth Management, said, "Inflation could remain elevated," adding, "In a high inflation environment, growth investing strategies may face a pullback."
European stocks were mixed. The Euro Stoxx 50 index is up 0.14% from the previous session, at 6,070.46.
France's CAC 40 and Britain's FTSE 100 fell 0.30% and 0.06%, respectively, over the same period, while Germany's DAX declined 0.40%.
Front-month West Texas Intermediate (WTI) for July delivery this year rose 0.16% from the previous session to $90.70 a barrel.
