Recently, while market attention has been focused on sectors like artificial intelligence and semiconductors, another theme—machine tools—has been quietly reaching new highs. Since the beginning of 2026, the China Machine Tool ETF (159663), a relatively small-scale ETF, has delivered remarkable performance. As of May 8, its net value growth rate for the year has reached 40.26%, ranking among the top performers in equity ETFs. This performance is not coincidental but the result of multiple converging factors. Behind the data lies a wave of manufacturing upgrades currently underway and a historic opportunity for China's industrial machine tools to transition from "large but not strong" to "high-end and sophisticated." 01 Accelerating Recovery, Comprehensive Demand Revival Since the third quarter of last year, the machine tool industry's prosperity has begun to recover comprehensively, with an accelerating trend continuing into the first quarter of this year. At the micro level, order books from leading machine tool manufacturers confirm the industry's genuine recovery. Several top companies in the machine tool sector achieved double-digit growth in their first-quarter performance. Many enterprises reported in institutional surveys that machine tool orders have been robust this year, with high capacity utilization rates and even delivery constraints for some high-end models. This recovery is not merely a cyclical rebound but a structural boom driven by multiple downstream demands, including AI computing infrastructure, semiconductors, new energy vehicles, and humanoid robots. In particular, the demand for liquid-cooled plate processing driven by AI server construction and the substantial need for precision components ahead of humanoid robot mass production have opened new growth avenues for the machine tool industry. 02 Accelerating Domestic Substitution, Timely High-End Breakthroughs For a long time, China's machine tool industry has been perceived as "large but not strong." However, this situation has undergone subtle changes in recent years. In 2025, China's machine tool industry's numerical control rate was approximately 51%. While there remains a gap compared to the 70%-80% levels in developed countries like the United States, Germany, and Japan, this gap is rapidly narrowing. In 2025, China's metalworking machine tool production value reached 219.8 billion yuan, a year-on-year increase of 6.9%. Meanwhile, import volumes and values saw only slight growth, indicating that domestic high-end machine tools are gradually meeting market demand, with the substitution process accelerating. Concurrently, export data were equally impressive: in 2025, machine tool export value increased by 14.60% year-on-year, with the average export price surging by 40.19%, demonstrating significant progress in high-end transformation. Notably, policy support has reached unprecedented levels. The implementation of the "Mechanical Industry Steady Growth Work Plan (2025-2026)" and the "Industrial Machine Tool High-Quality Standard System Construction Plan" continues to drive product transformation toward high-end and intelligent development. As the "mother machine" of manufacturing, industrial machine tools' strategic importance continues to rise, with new energy, artificial intelligence, and low-altitude economy sectors providing broad application scenarios. Simultaneously, domestic substitution for upstream core components is accelerating. Since early 2026, imported numerical control systems have faced extended delivery cycles or even shortages, offering a rare substitution window for domestic numerical control system companies. 03 From Traditional Manufacturing to Intelligent Manufacturing A deeper analysis of the strong performance of the China Machine Tool ETF this year reveals a key conclusion: beyond performance factors, this round of gains essentially represents a reconstruction of valuation logic. Traditionally, machine tools have been viewed as a cyclical traditional manufacturing sector, with valuation levels long suppressed. However, the current industrial machine tool sector is no longer limited to traditional machine tool enterprises but includes high-growth segments such as humanoid robots, PCB equipment, and nuclear fusion. The China Machine Tool ETF tracks the CSI Machine Tool Index, which selects 50 listed company securities from the Shanghai and Shenzhen markets involved in the manufacturing and services of machine tool systems and their key components to reflect the overall performance of the machine tool industry. Its top ten holdings include Huagong Tech 华工科技, Han's Laser 大族激光, China Tungsten and Hightech Materials 中钨高新, Xiamen Tungsten 厦门钨业, Homa 豪迈科技, Leader Harmonious Drive Systems 绿的谐波, and Inovance Technology 汇川技术. These companies not only hold competitive advantages in traditional machine tool fields but also play significant roles in emerging areas such as core components for humanoid robots, AI computing infrastructure, and strategic metals. This diversified composition means the China Machine Tool ETF's valuation incorporates both traditional business valuations and emerging growth expectations. 04 Three Logics Supporting Medium- to Long-Term Investment Value In the short term, the China Machine Tool ETF has seen considerable gains. However, in the medium to long term, the machine tool sector's investment value remains supported by solid logic. First, the equipment renewal cycle is approaching. China's machine tool industry has entered a period of robust equipment renewal demand. Based on an approximate 10-year renewal cycle for machine tools, equipment purchased in 2016-2017 will peak for renewal in 2026-2027. Supported by national policies promoting large-scale equipment updates, demand for numerical control upgrades and renewals in China's machine tool industry is expected to grow steadily, further advancing the industry's high-end numerical control levels. Second, the catalyst of humanoid robot mass production. Tesla's Optimus Gen3 is expected to commence production in mid-2026, with large-scale mass production in 2027. Domestic humanoid robot companies are also anticipated to achieve significant commercial production growth in 2026. As the core manufacturing foundation for humanoid robots, industrial machine tools and related precision components and actuators are entering a critical period of transition from "traditional manufacturing" to "intelligent manufacturing." This trend will bring sustained incremental demand to the machine tool industry. Third, the overseas expansion logic is gradually materializing. In 2025, China's average machine tool export price increased by 40%, indicating growing international recognition of domestic high-end machine tools. With rising orders from overseas markets such as Japan and Europe, and continuous expansion of domestic companies abroad, the overseas expansion logic for the machine tool industry is gradually being realized, providing new momentum for sector growth. Of course, investors should also be aware of potential risks. Intensified industry competition may pressure corporate profitability, and delays in product development or capacity construction could impact growth prospects. From an allocation perspective, although the machine tool sector has seen significant short-term gains, its medium- to long-term growth logic remains clear, with demand from multiple application scenarios gradually translating into orders. For investors optimistic about China's manufacturing upgrades, domestic substitution, and the humanoid robot industry, the China Machine Tool ETF still holds substantial allocation value. Adopting strategies like dollar-cost averaging or phased investments is recommended to share in the industry's long-term growth benefits. After all, this "intelligent manufacturing revolution," driven by technological upgrades, policy support, and demand explosion, has only just begun.
