Currently (2026-06-08) the industrial line has repeatedly strengthened, showing a trend of vigorous development.
Automation equipment is driven by the mass production of physical AI/robots (Tesla Optimus V3, Yushu IPO, industrial automation recovery), and the leaders (Juneng Shares 30cm, Eston Daily Limit, Green Harmonic + nearly 9%) have reached a high level; non-metallic materials are driven by geo-conflicts (sulfur price increase, high-end graphite/quartz supply and demand tight, AI upstream consumables shortage), Guangdong-Guangxi Shares daily limit, Quartz Shares, Fangda Carbon, etc. have followed suit.
The day after the main line breaks out/during the differentiation period, funds will find stagflation targets in the same sector that are “low, low valuation, and have compensatory growth logic” to make high and low cuts. The core is to follow the four steps of “track attributes → screening criteria → target range → risk control” to dig up and make up for the increase.
1. Automation equipment sector: ideas for supplementary growth mining
– Track segmentation: industrial robots (complete machines, parts), industrial control (servos/PLC), intelligent detection/machine vision, general automation (forklifts, machine tool peripherals), AI special equipment (optical modules/PCB/lithium battery equipment).
– Screening criteria for compensatory growth:
- Low position: The increase in the past 3 months is <20%, the stock price is at a low range in the past 1 year or has bottomed out in a long-term sideways trend (for example, after the adjustment of the automation sector in the first half of 2025-2026, the valuation returns to the bottom of the cycle).
- The valuation is reasonable: the PE of the complete machine/industrial control is 15 to 25 times, and the PE of parts and components is 20 to 30 times (the valuation discount is obvious compared to the valuation of leading Green Harmonics, Inovance Technology, etc.).
- There are orders/business anchors: 2026Q1-Q2 orders will pick up (automation equipment industry orders + 22% year-on-year, forklifts, machine tools, and industrial control growth are restored), or cut into the robot supply chain (second curve).
- Technical form: heavy volume at the bottom, initial divergence of moving average adhesion, no continuous sharp rise (big positive is better in the first day of heavy volume).
– The direction of supplementary bid increase (not recommended, for carding purposes):
- Industrial control/general: Xinjie Electric (603416, PLC + servo, PE about 18 times, bottom volume), VEICHI Electric (688698, frameless torque motor +
Industrial control, second curve of robots, PE about 25 times), Lesai Intelligence (002979, motion control, bottom stabilization). - Forklift/General Automation: Hangcha Group (603298, export + electrification, PE about 12~14 times, low), Anhui Heli (600761, similar logic, low valuation), Neway CNC (601882, machine tool order repair, PE about 20 times).
- Machine vision/inspection: Tahoe Intelligent (603656, machine vision intelligent detection, bottom reversal form), Tianzhun Technology (688003, machine vision + robot vision guidance, low position on the Science and Technology Innovation Board).
- Automation equipment parts: Wuzhou Xinchun (603667, bearing + screw, robot chain supplementary increase), Changsheng Bearing (300718, sliding bearing, low position).
– Operation: Prioritize the target of “bottom first release volume + valuation discount + order/second curve verification”, wait until the 5-10 day line is stepped back to buy low, and do not chase the intraday pulse; if the leader (Eston, Huichuan, Green) is sluggish and differentiated, the compensating stocks can generally rotate for 3-5 days, and break the positive line to start half of the physical stop loss.
2. Non-metallic materials sector: ideas for supplementary growth mining
–
Track segmentation: high-end industrial non-metals (graphite electrodes, special graphite, high-purity quartz sand/products), electronic materials (photoresist/CMP pads, ceramic substrates), periodic non-metals (sulfur/sulfate, phosphorus and fluorine materials, titanium dioxide, etc.), AI upstream consumables (optical module ceramics, quartz devices).
– Compensatory growth screening criteria:
- Low position: The increase in the past 3 months is <15%, it is at the low level of the box in the past 1 year or has not broken through the long-term moving average suppression.
- Low valuation/performance turning point: PE of cyclical products is below the 30% percentile in the past five years (such as graphite electrodes, ordinary non-metals), or electronic materials PE is 20 to 30 times (relative to leading quartz shares, Feilihua discount); 2026Q1-Q2 gross profit margin improved month-on-month (product prices stabilized and rebounded, costs fell).
- Having products/order anchors: Benefiting from the current catalysis (recovering supply and demand of graphite electrodes/special graphite, shortage of high-purity quartz, rising sulfur prices, and increased volume of AI ceramics/optical module materials), the products have price increases or certification breakthroughs, rather than pure concepts.
- Technical form: After a long period of sideways trading, there is moderate heavy volume, the moving average is glued together, and there is no continuous sharp rise.
– The direction of supplementary bid increase (not recommended, for carding purposes):
- Graphite/carbon-based: Ningxin New Materials (839719, special graphite on Beijing Stock Exchange, rising with Dongfang Carbon but with a small increase), Fangda Carbon (600516, graphite electrode leader, UHP quotation stabilized, PE extremely low, moderate volume at the bottom).
- High-purity quartz/electronic ceramics: Feilihua (300395, electronic-grade quartz leader, valuation discount to quartz shares), China Ceramics Electronics (003031, ceramic substrate, 1.6T optical module volume, PE about 30 times, adjusted low), Bomin Electronics (603936, ceramic substrate/PCB, low).
- Cyclic non-metals (price increase chain): Yuntu Holdings (002539, phosphorus + sulfur downstream, sulfur price increase transmission, low valuation), Silte (002538, phosphorus and sulfur composite, low price), Longgao Holdings (605086, kaolin, low price of non-metallic materials).
- Electronic materials: Yake Technology (002409, precursor/special gas, bottom shock but not speculation), Dinglong Co., Ltd. (300054, CMP pad/PI slurry, low-level institutional configuration).
– Operation: Non-metallic materials are mostly cyclical/electronic materials. The supplementary increase relies on “verification of product price increase + low volume increase”. Priority is given to targets with real quality and price support (graphite electrode quotations have risen steadily for two consecutive weeks, quartz supply gaps are confirmed); those who purely follow the trend without product price increases will only do ultra-short-term operations, breaking the 5-day moving average; cyclical products strictly control warehouse orders to be less than or equal to 10%.
3. General mining process (actual combat)
- Confirm the continuity of the main line: for automation equipment, look at robot mass production data (Optimus V3 debut, Yushu IPO, Q2 automation orders >20% year-on-year); for non-metals, look at whether product quotations (graphite electrodes, quartz sand, sulfur) have risen for two consecutive weeks, and leading performance guidance has been raised.
- Preliminary screening of the “three lows” pool: low (small increase in the past three months), low valuation (sector PE percentile <30%), low institutional position (institutional underweighting, small resistance to compensatory growth).
- Add business anchor filtering: Automation equipment must have evidence of “recovery in orders/robot supply chain entry”; non-metallic equipment must have evidence of “product price increase/breakthrough in electronic material certification” to eliminate the concept of pure speculation.
- Technical buying point: The first high-volume positive at the bottom (volume ratio > 1.5 times average volume), the moving averages are bonded and diverged, buy low when it steps back to the 5-10 day line and shrink; automatically make up for the increase and hold for 3-5 days (rotation logic), if the price increase of non-metal products continues, it can be extended to a wave of trends (break the 10-day line).
- Risk control: Automatically make up for the increase and trigger half stop loss of the positive entity; non-metallic products break the 5-day line (short-term) or the product price increase is proven to be falsified; single position automation ≤ 15%, non-metallic ≤ 10%.
In short: for automation equipment to make up for growth, look for “bottom volume + low valuation industrial control/forklifts/vision + orders/robot second curve”; for non-metallic materials to make up for growth, look for “long-term lows + product price increases/electronic material certifications + valuation discounts”.
The supplementary increase after the main line breaks out is a “limited time window (3~5 days)”. Do not chase the intraday high, wait for the retracement to reduce the volume and buy at low prices. Strictly verify the product/order logic to remove the weak and retain the strong.

Interactive tissue paper: Are you better at digging for automation equipment to make up for the increase (industrial control/forklift/vision, relying on orders + valuation), or non-metallic materials (graphite/quartz/cyclical products, relying on product price increases + low prices)?
