Huatai Securities: South Korea's high export growth indicates that global AI supply chain trade is still on an upward trend, and the Asian AI supply chain is expected to continue to benefit.
Mars Finance reported on July 6th that a research report from Huatai Securities pointed out that the continued strong performance of AI chain exports drove South Korea's June exports to significantly exceed expectations, with the trade surplus reaching a new historical high. Looking ahead, leading indicators show that AI chain trade will maintain high growth, and South Korean exports are expected to continue their strong performance, potentially driving South Korea's nominal GDP to maintain a relatively high growth rate. In the short term, the Philadelphia Semiconductor Index, which leads South Korean semiconductor exports by about four months, remains high year-on-year, indicating that the strong performance of South Korean semiconductor exports is likely to continue; at the same time, against the backdrop of strong AI demand, memory prices are still rising, and prices will continue to support nominal exports. The high growth of South Korean exports indicates that global AI chain trade is still on an upward trend, and the AI supply chain in Asia, including South Korea and China, is expected to continue to benefit.

Serenity: SemiAnalysis is accused of "building positions after shorting," and related optical communication companies have been included in the cooperative ETF.
Mars Finance reported on July 5th that Serenity, citing UDN Money, stated that research firm SemiAnalysis has sparked market controversy due to a series of actions. In June, SemiAnalysis released a research report citing low yield rates for CPO (co-packaged optics) technology and potential delays in product launches, indicating a bearish outlook on the optical communication sector and causing a sharp decline in related stock prices. Subsequently, the firm partnered with Tema ETFs to launch an optical communication-themed ETF. Notably, companies like Himax Technologies and Lumentum Holdings, which SemiAnalysis heavily criticized in its "Powered Down, Lights Off" report, were included in the ETF's holdings after the sector's correction, sparking market discussion about its "bearish first, then allocation" strategy.
Beijing Junzheng: Due to the continued price increase of the company's memory chips, the gross profit margin is expected to increase sequentially in each quarter.
According to Mars Finance, Beijing Junzheng (300223.SZ) released an investor relations activity record announcement, stating that DRAM prices have risen significantly. Domestic customers began adjusting prices in the first quarter, and continued to do so in the second quarter. Overseas customers also began adjusting prices gradually. Revenue and gross margin are expected to continue to grow in the second quarter. Prices are expected to continue rising in the third quarter, while the pricing policy for the fourth quarter will not be determined until then. However, current supply in the fourth quarter appears to be relatively tight, with the possibility of further price adjustments. As customers replace some DRAM solutions with SRAM products, the prices of some SRAM chips also increased in the second quarter. NOR Flash prices rose in both the first and second quarters, but the overall increase was smaller than that of DRAM. Although NOR Flash capacity is also tightening, it is much better than DRAM. The company's Flash product line achieved good revenue growth in the first quarter, with sales volume growth accounting for a large proportion. Prices in the third quarter will be determined based on specific products and customer situations, and not all prices will necessarily be adjusted. Due to the continued rise in the company's memory chip prices, gross margin is expected to increase sequentially each quarter. (Cailian Press)
