On 6/2, the DJIA index closed the trading session with a 2.5% increase, reaching 50,115 points, its highest level to date. The S&P 500 and Nasdaq Composite also saw strong gains, rising by 1.9% and 2.2% respectively. Nine of the 11 sectors within the S&P 500 index rose, led by information technology and industrials.

The market brightened as chip company stocks surged. Shares of Nvidia, the world's most valuable company, rose by 7.8%. AMD increased by 8.3%, and Broadcom added 7%. The PHLX semiconductor index, which tracks the group, closed the week's final session up 5.7%.

Investors expect this sector to benefit from the wave of investment in artificial intelligence (AI) data centers. Amazon announced on 5/2 that it plans to increase capital expenditure by 50% this year, intensifying the race for AI technology dominance. A day earlier, Alphabet made a similar announcement.

This strong performance on the week's final session ended Wall Street's previous three consecutive losing sessions. Some software companies faced pressure due to concerns that AI would increase competition and erode their profit margins. Investors also worried about high valuations after years of strong growth in AI-related stocks.

"Recent trading has been quite volatile, with several sell-offs. However, I think there is enough evidence of genuine demand for AI products, their potential, and the necessity of significant expenditures to achieve that," commented Ross Mayfield, an investment strategist at Baird. He suggested that when prices hit a floor, a group of investors would look to buy in.

Software and data services stocks also recovered after recent declines. CrowdStrike and Palantir both rose by more than 4%. The S&P 500 Software & Services index increased by 2.4%, ending a streak of seven consecutive losing sessions.

For the entire week, the DJIA index rose by 2.5%. The S&P 500 lost 0.1%, and the Nasdaq fell by 1.9%.

The DJIA outperformed this week, reflecting a trend of investors diversifying their portfolios. They are shifting away from the technology stocks that have led Wall Street in recent years, moving towards companies that have not yet experienced such growth.

To date, more than half of the companies in the S&P 500 index have released their quarterly financial reports. Approximately 80% exceeded forecasts, according to data firm LSEG.
