NVIDIA Announces CPO Mass Production; AMEC Net Profit Forecasts Surge Up to 310% - Tech-Focused STAR50 ETF (588330) Rallies 6.25%
On August 4th, A-share markets saw broad gains, with the ChiNext Index leading the rally with a 5.64% increase. The STAR50 ETF (588330), a hard-tech broad-based fund covering 50 high-growth leaders from the STAR Market and ChiNext, surged to an intraday high of 6.25%, closing 5.68% higher and reclaiming its 5-day moving average. Capital has been actively flowing into the hard-tech sector, with data showing the STAR50 ETF (588330) attracted net inflows of 108 million yuan over the past five trading days and 469 million yuan over the past 60 trading days.
Among the ETF's constituent stocks, optical module giants led the gains. Tianfu Communication surged over 17%, while Eoptolink Technology and Zhongji Innolight both rose over 13%. Semiconductor leader VeriSilicon gained over 12%, and PCB leader Shengyi Technology advanced over 7%.
Market attention is focused on the optical module and semiconductor sectors. In optical modules, NVIDIA Senior Vice President Gilad Shainer announced that Co-Packaged Optics (CPO) is entering mass production. CITIC Securities stated that the AI investment return cycle has materialized, maintaining a bullish outlook on the optical communication sector. As cloud companies' earnings continue to confirm AI's role in driving business growth, AI cluster scale is expected to expand further. Optical interconnection, a critical component of cluster networks, is poised for sustained high growth driven by three factors: increased GPU allocation ratios, higher port speeds, and the replacement of copper with optical fiber. The firm is optimistic about the medium-to-long-term prosperity of the optical communication sector.
In the semiconductor sector, on the evening of August 3rd, Advanced Micro-Fabrication Equipment Inc. China (AMEC) released its first-half 2026 performance forecast, projecting revenue of approximately 6.691 billion yuan, a 34.89% year-on-year increase, and net profit attributable to shareholders of between 2.7 billion and 2.9 billion yuan, a staggering 282% to 311% surge. This is not an isolated case. Driven by AI, the global semiconductor equipment boom cycle is strengthening. Dongwu Securities noted that the explosive demand for HBM is driving both memory process upgrades and higher capital expenditure. Thin-film deposition, etching, and measurement equipment together account for over 50% of memory expansion investment.
Fundamentally, the hard-tech sector is experiencing a wave of positive earnings surprises. As of August 3rd, among the 50 constituent stocks in the STAR50 ETF's underlying index, 14 had disclosed their 2026 interim performance forecasts. All of these companies reported both forecasted profits and earnings growth. Longsys leads with a projected net profit of up to 11 billion yuan, while eight other constituents, including Eoptolink Technology, are expected to see net profit growth of over 100% year-on-year. China Galaxy Securities pointed out that with the peak season for interim reports in August, investors should focus on sectors with strong earnings visibility and clear growth. Industrial Securities believes that high-quality hard-tech assets, which have become more attractively valued, represent a compelling opportunity for long-term allocation.
At this juncture, rather than betting on a single niche, a broad-based hard-tech ETF offers a more efficient way to capture the entire technology rally. The STAR50 ETF (588330) and its OTC feeder funds (Class A: 013317, Class C: 013318) track an index that selects the 50 largest strategic emerging industry companies from the STAR Market and ChiNext. This ETF covers popular themes like optical modules, semiconductors, and batteries, with top holdings including Eoptolink Technology, Zhongji Innolight, CATL, and Cambricon Technologies. With a 20% daily price fluctuation limit, the ETF provides low-barrier access to the growth potential of the dual-innovation board. Additionally, the ETF is eligible for margin trading and the Stock Connect program, making it an efficient tool for investing in new productive forces.
