On Friday, Micron Technology, the top stock by trading volume, closed up 15.49%, hitting a record high. Its trading volume reached $45.683 billion, and its market capitalization surpassed $800 billion. Memory chip manufacturers saw broad gains on Friday. Since late April, both Micron Technology and SanDisk have surged over 40%, becoming the best-performing components of the Philadelphia Semiconductor Index. Analysts note that the core driver of this rally is the sustained rise in memory chip prices. Since the outbreak of the Iran conflict in late February, spot prices for DRAM and NAND flash memory chips have increased by approximately 25% and 18%, respectively. Factors contributing to supply tightness include: South Korean manufacturers, which account for over 60% of global memory chip supply, have been affected by shipping disruptions and rising insurance costs due to Middle East conflicts, impacting shipments; AI server demand for high-bandwidth memory is consuming significant capacity, squeezing supply for traditional PCs and smartphones; and major manufacturers have reduced capital expenditures over the past two years, limiting their ability to quickly ramp up production in response to growing demand. SanDisk, ranked second, closed up 16.60%, also reaching a record high, with a trading volume of $29.707 billion. Memory chip manufacturers experienced broad gains on Friday.

NVIDIA, ranked third, closed up 1.76%, with a trading volume of $28.929 billion. The AI chip sector saw broad gains on Friday. Tesla, ranked fourth, closed up 4.02%, with a trading volume of $27.462 billion. Analysts highlight that Tesla's industrial attributes are often overshadowed by its automotive business. Its Gigafactories in Texas and Germany produce millions of 4680 battery cells, thousands of Optimus robots, and dozens of Megapack energy storage systems annually. Tesla's energy storage business revenue grew 80% year-over-year in the first quarter, with a gross margin exceeding 20%, higher than the automotive segment's 15%. The market appears to have not yet fully priced in the long-term potential of its energy storage operations. Intel, ranked fifth, closed up 13.96%, with a trading volume of $27.167 billion. Reports indicate that Intel has reached a preliminary agreement with Apple to manufacture some chips for Apple devices. The two companies have been negotiating for over a year, though it remains unclear for which Apple products Intel will produce chips. Advanced Micro Devices, ranked sixth, closed up 11.44%, hitting a record high, with a trading volume of $25.15 billion and a market capitalization exceeding $700 billion. The AI hardware sector saw broad gains on Friday. Qualcomm, ranked eleventh, closed up 8.17%, reaching a record high, with a trading volume of $8.216 billion. Qualcomm has risen for four consecutive trading days. On May 6 local time in San Diego, the company officially announced the launch of the fifth-generation Snapdragon 6 and Snapdragon 4 mobile platforms, further expanding its smartphone chip portfolio. Leveraging optimizations in performance, power efficiency, and connectivity, the new platforms aim to deliver a more stable and smooth mobile experience to users worldwide. Rocket Lab USA, Inc., ranked thirteenth, closed up 34.22%, with a trading volume of $7.603 billion. The company's latest earnings report shows that for the first quarter of 2026, revenue reached $200.3 million, up 63.5% year-over-year, surpassing analysts' expectations of $189.6 million. GAAP gross margin hit a record high of 38.2%. The loss per share narrowed to 7 cents from 12 cents in the same period last year, indicating continued improvement in profitability. Concurrently, on the day of the earnings release, the company announced several significant business developments: the largest launch contract in its history with a confidential customer; selection for the "Gold Dome" space-based interceptor project in collaboration with RTX Corp; a $30 million hypersonic test flight agreement with Anduril Industries; and plans to acquire robotics company Motiv Space Systems. The company's total order backlog grew 20.2% quarter-over-quarter to $2.2 billion, significantly exceeding market expectations of $1.99 billion. CoreWeave, Inc., ranked nineteenth, closed down 11.40%, with a trading volume of $5.501 billion. As of Friday's close, the stock has declined for two consecutive trading days. The latest earnings report from CoreWeave shows that adjusted operating profit for the first quarter of 2026 plummeted to $21 million, with an adjusted operating margin of just 1%, compared to $163 million and a 17% margin in the same period last year. CoreWeave attributed the margin contraction primarily to the rapid expansion of active computing capacity—costs related to infrastructure deployment are recognized ahead of revenue, leading to temporary compression in profit margins. Notably, under GAAP, CoreWeave reported a net loss of $740 million for the first quarter, with a net loss margin of 36%, compared to a loss of $315 million in the prior-year period. Net interest expense reached $536 million, a significant increase from $264 million in the same period last year, contributing to the widening net loss. Additionally, the company expects second-quarter revenue to be between $2.45 billion and $2.6 billion, falling short of market expectations.
