In an unexpected turn of events, the A-shares market experienced a notable surge in mid-January, particularly on January 9th, where three major indices exhibited diverse movements, yet specific stocks showed remarkable performancesClose to a hundred stocks reached their daily trading limits, while only about ten faced declines, indicating an overall bullish sentiment.

The humanoid robot sector, in particular, witnessed an impressive rally in the afternoon session, with nearly ten stocks, including prominent players like Zhaomin Technology and Yibo Technology, hitting their upper price limits by the close of tradingAdditionally, the liquid cooling server segment also exhibited strong performance, with firms such as Kangsheng Co., Feilong Co., and Shuangliang Energy all reaching their daily highs, showcasing a robust investor interest in these emerging technologies.

This surge in the humanoid robot and liquid cooling sectors raises critical questions about the driving forces behind these movements and whether they can sustain their momentum in the coming weeks

A closer examination into these sectors reveals a combination of technological advancements and strategic corporate decisions fueling this growth.

Focusing on the humanoid robot concept, this sector saw a significant uptick on January 9th, following several positive announcements regarding advancements in humanoid robotsNotably, on January 8th, in a recent interview, Elon Musk mentioned a potential tenfold increase in production of Tesla’s Optimus humanoid robot by 2026, aiming for an impressive 50,000 to 100,000 units by the following yearMusk also disclosed that three patients had successfully received Neuralink brain-machine interface chips, hinting at the broader applications of this technology.

Earlier, Musk expressed enthusiasm about upcoming updates for Optimus, indicating that the project has been progressing exceptionally wellThis optimism has built upon his previous statements regarding substantial hardware revisions anticipated by late 2024 or early 2025 and the expectation that over a thousand Optimus robots could be tested at factories during that phase.

Moreover, during the 2025 Consumer Electronics Show in Las Vegas, numerous manufacturers introduced humanoid robot products, with NVIDIA’s founder Jensen Huang declaring that the era of humanoid robots is fast approaching, indicating a consensus among industry leaders about the burgeoning potential of this technology.

According to Guohai Securities, the year 2024 is poised to witness significant growth in China's humanoid robot industry, fueled by technological advancements and supportive government policies

The anticipated entrance of various manufacturers into the robotics space, coupled with ongoing investments in Artificial Intelligence (AI) and large-scale models, will further accelerate the construction and commercialization of the humanoid industry chainAnalysts predict that 2024 heralds the commercial breakthrough of humanoid robots, with rising domestic and international applications expected.

Turning to the liquid cooling server segment, another strong cohort of stocks made headlines on the same trading day, including Kangsheng Co., Feilong Co., and several others reaching their daily limitsThe surge aligns with Microsoft's recent announcement of an astonishing $80 billion investment in data centers for AI model training and cloud applications planned for the fiscal year 2025. It underscores the escalated strategic focus that tech giants like Amazon, Google, Microsoft, and Meta are placing on developing generative AI and massive language models, amounting to approximately $300 billion in capital expenditures by 2025.

Research suggests that the capital demand for AI computing in data centers will not only usher in a wave of new chip products but will also sustain substantial investment interest in liquid cooling technologies

According to Shen Xiangyang, a fellow at the National Academy of Engineering, the next decade may see computing power requirements soar by a staggering million-fold, far exceeding traditional growth forecastsReports indicate that the Chinese AI server market is expected to boom between 2023 and 2025, reaching $13.4 billion, $30.7 billion, and $56.1 billion, with respective growth rates of 101%, 128%, and 83%.

Analysts from China Merchants Securities argue that the previous notion of liquid cooling merely as an advanced heat dissipation technology is now transitioning to a comprehensive deployment phase propelled by substantial demand from data centersCompanies like Vertiv have adjusted their performance targets upwards, anticipating considerable growth in revenue and profit margins as they expand into liquid cooling product offerings.

Despite recent production delays with NVIDIA's Blackwell chips, their data center business continues to demonstrate extraordinary growth, reflecting ongoing robust demand for GPUs

Meanwhile, companies such as Alibaba and Tencent are aggressively increasing their capital expenditures, indicating a strategic push for enhanced computing capabilities.

The liquid cooling technology sector is bracing itself for significant growth over the next five years, with expectations of a compound annual growth rate (CAGR) exceeding 50%, particularly as operators begin larger-scale applicationsThe projections from analysts highlight an extensive opportunity in the cooling market, especially with NVIDIA anticipating mass shipments of new liquid-cooled products in 2025, presenting a fertile ground for domestic suppliers eager to capture a share of this expanding segment.

Shanghai Securities reports a continuing influx of investments in computational infrastructure by internet firms, signifying that as computing scales increase, the demand for more efficient server cooling solutions will persistently rise
