On Friday, August 7, the electronic sector attracted a net capital inflow of over 30.8 billion yuan for the entire day, ranking first among all 31 Shenwan primary industries in terms of capital absorption. The Huabao Electronic ETF (515260), which gathers core leaders of the electronic sector, saw its intraday price rise up to 3.94%, closing up 3.36%. It successfully reclaimed the 20-day moving average and secured a four-day winning streak. Among its constituent stocks, PCB (Printed Circuit Board) leaders led the gains significantly, with seven PCB leaders occupying slots in the top ten gainers of the ETF. Notably, Shengyi Technology Co.,Ltd. and Shenzhen Kinwong Electronic Co.,Ltd. hit the daily limit up, while Shengyi Electronics surged over 12%, and Shennan Circuits and WUS Printed Circuit Co., Ltd. followed suit with substantial gains. Storage chip concept stocks also performed well, with GigaDevice rising over 8%, and Longsys Electronics and Biwin Storage Technology gaining over 5%.

The surge in PCB stocks is largely attributed to a Goldman Sachs research report and the commencement of large-scale shipments of NVIDIA's Rubin platform. On August 6, Goldman Sachs significantly raised its forecast for the PCB market size in its latest report. The investment bank now predicts that the global AI server PCB market will reach $37.5 billion by 2027, a 38% increase from its previous forecast, and will further expand to $84 billion by 2028. Additionally, NVIDIA's Rubin AI servers have reached the starting point for scaled shipments, with the first batches of cabinets being deployed in data centers for clients like OpenAI and Google. It is estimated that by the end of December, total shipments for the full year 2026 will reach 8,000 cabinets, reflecting accelerated AI infrastructure construction driving demand for PCBs. Industry insiders point out that the most important signal from the Goldman Sachs report is the redefinition of the value anchor for AI hardware. The value center of the AI industry chain is shifting from "computing chips" to "interconnection infrastructure." When the PCB value in a single AI rack reaches the tens of thousands of dollars level, PCBs are no longer a supporting player but a key hardware determining the performance of AI clusters. China Securities Co., Ltd. notes that, driven by AI, the global PCB industry is entering a new upward cycle. With the increasing demand for orthogonal backplanes and the upgrade of CoWoS processes, PCBs will become more similar to semiconductors, with their value steadily increasing. Cloud vendors like Amazon, Meta, and Google, which have weaker in-house chip design capabilities compared to NVIDIA, have higher requirements for materials like PCBs, making their value proposition more elastic.

On another front, the market is closely watching the question of whether the storage chip price increase trend can be sustained. Guojin Securities predicts that the storage upcycle could extend into 2027, with the core driver being a persistent supply shortage. The training and inference of large models are generating massive storage demand, while wafer fabs are constrained by construction and equipment procurement lead times. New capacity releases take about two years, making it difficult for manufacturers' expansion plans to match the surge in demand. This supply-demand gap will support storage prices and scale to new levels.

With themes of price increases, AI, and independent controllability potentially running through the electronic sector for the entire year, the Huabao Electronic ETF (515260) and its linked funds (A Class: 012550, C Class: 012551) passively track the CSI Electronics 50 Index. This index focuses on the semiconductor, component, and consumer electronics industries, encompassing popular concepts such as PCB (e.g., Dongshan Precision Manufacturing), storage chips (e.g., Longsys Electronics), semiconductor equipment (e.g., ACM Research Shanghai), advanced packaging (e.g., JCET Group), glass substrates (e.g., BOE Technology Group), semiconductor silicon wafers (e.g., NSIG), and MLCC (e.g., Shenzhen Sunlord Electronics). It is deeply tied to global tech leaders, with constituent stocks within the supply chains of Apple, NVIDIA, and Google.
