Heavyweights drive a higher-volume rebound; funds may return after the first divergence in robotics
Cailian Press believes that spontaneous buying and higher turnover improved the quality of the rebound, although short-term sentiment diverged from the index. Robotics remains the leading theme, while strength in computing hardware and chip heavyweights offers a reason to watch for a possible style rotation.

Key takeaway
Cailian Press believes that a spontaneous increase in market turnover improved the quality of the rebound, but short-term sentiment remains weak. The first divergence in robotics and strength in technology heavyweights will influence subsequent capital allocation.
Why is the higher-volume rebound considered stronger in quality?
On 28 October, the index opened higher, fell, and then strengthened steadily, while turnover rose markedly from the previous trading day. Cailian Press believes the higher turnover came from spontaneous market buying rather than purchases to support the market, making the rebound stronger in quality.
However, short-term sentiment diverged from the index: the rate of stocks failing to hold their daily upper limit was relatively high, and the rate at which limit-up stocks achieved another limit-up was relatively low. Trend-driven stocks performed better. Cailian Press expects the short-term rebound to be uneven and is not yet considering a style rotation; if the rebound gains momentum, investors should watch for a possible rotation.
What do divergence in robotics and strength in technology heavyweights mean?
The robotics sector rallied broadly and retained its position as the leading theme, but pulled back somewhat after its afternoon peak. It was also a major reason for the day's relatively high rate of stocks failing to hold their daily upper limit. Cailian Press believes that the first divergence after a theme becomes the market consensus often presents more opportunity than risk; if the sector continues to weaken the next day, funds may position for a return.
The index remained strong but fluctuated in the afternoon, relying mainly on computing hardware, chips and semiconductors. Sentiment-driven technology stocks performed only modestly, while funds focused more on heavyweights. This differs from the allocation choices made during previous rebounds and is why Cailian Press advises watching for a style rotation.
Gains were broadly distributed across the market. Consumer stocks diverged after a brief surge the previous day, while defensive areas such as high-dividend stocks weakened. Cailian Press believes that broad gains in a weak market are often followed by divergence the next day, making it more important to focus on the leading theme.
What are the specific links in the robotics supply chain?
Zhongxin Fluoride Materials' DFBP is a key monomer in PEEK synthesis. PEEK is used to reduce weight in robot joints and transmission systems because it withstands high temperatures and corrosion and has low density. Producing 1 tonne of PEEK consumes approximately 0.8 tonnes of DFBP, which accounts for 30% to 40% or even more of PEEK's total cost.
Cailian Press says Zhongxin Fluoride Materials has DFBP capacity of 5000 tonnes per year, serves several PEEK manufacturers and is expanding into crude-product purification services. Its vertical integration from fluorite and hydrofluoric acid through to DFBP helps reduce raw material costs and the risk of fluorite price fluctuations.
The self-lubricating spherical plain bearings in which Changsheng Bearing has invested can meet the impact and long operating-cycle requirements of robot joints. According to the report's estimates, joint bearings could be worth approximately 5200 yuan per humanoid robot, with mass production of one million units corresponding to a market of approximately 5.2 billion yuan. The company has established partnerships with robot manufacturers including Unitree Robotics.
