Goldman Sachs: The range of stock market gains in the second half of the year will expand, and the growth of profits of technology companies will be a key driving force.

Goldman Sachs' global chief stock strategist, Peter Oppenheimer, said that global stock markets are expected to continue their strong rally in the second quarter, with the profit growth of technology companies being a key driver. "As long as profit performance remains strong and the growth range expands, I believe the stock market will continue to rise in the second half of the year," Oppenheimer said. "The increase may not be as high as in the first half of the year, but I believe the growth will be broad-based." He pointed out that profit growth in the technology industry will continue, despite investors shifting their focus from data center and cloud computing platform operators to semiconductor and equipment manufacturers that support the artificial intelligence boom.
