The U.S. SOX chip index has nearly doubled this year, propelled by aggressive capital expenditure on artificial intelligence infrastructure. Individual performers have seen even more dramatic growth: Intel and Marvell Technology shares have more than trebled, Micron Technology has quadrupled, and Sandisk has surged by over 700%. This historic run contrasts sharply with the broader tech sector, where the Magnificent Seven are collectively down 4% for the year, with Microsoft and Meta recording declines of 24% and 15% respectively.

Economic uncertainty remains a persistent factor for the second half of the year. Federal Reserve rate-hike expectations linger as recent data suggests the U.S. economy may be running hot. Investors are now pivoting toward the upcoming June jobs report and May job openings data to gauge the labor market's health. Meanwhile, global volatility continues to impact currency markets, with the Japanese yen sliding to 40-year lows as speculative short positions reach two-year highs. In corporate restructuring, Comcast shares climbed nearly 5% following the announcement that it will spin off its media and entertainment assets, including NBCUniversal and Sky, into a separate entity.
