Technology and Valuation Game Behind the Strong Breakthrough of Jiao Cheng Ultrasound

The event occurred at 2025-12-17 17:15:42 (UTC+8). On that day, Jiao Cheng Ultrasound was included in the strong stock pool by tushare_strong_pool, with a closing price of 122.11 yuan hitting a 52-week high. Trading volume increased significantly, and intraday it not only broke through the previous consolidation zone of ¥108.86 but also stood above ¥115, indicating that short-term market sentiment is clearly bullish but we need to be vigilant of pullbacks [0]. The company won the “Best Technological Breakthrough Award” from TE Connectivity in niche areas such as low-voltage aluminum wire ultrasonic high-speed welding. This event has continued to boost confidence since its announcement on November 26. Meanwhile, the company covers multiple high-growth tracks including new energy vehicle wiring harnesses, power batteries, and semiconductor packaging, increasing the linkage of catalysts [1]. From a technical perspective, MACD has not出现 a death cross, KDJ is in a strong zone but not yet in extreme overbought territory, ATR% and average gain both show high volatility. The month-on-month increase in trading volume means a strong willingness to continue the trend. If the price holds above ¥115 with volume support in the coming days, it can be regarded as a confirmation of the breakthrough [0]. In addition, social and sector data reveal that this stock ranks among the top in the “Today’s Breakthrough of 5-Day Moving Average” list, showing that capital and investor attention are concentrating [2].

• Technological breakthroughs and industry recognition have an amplifying effect on technology-oriented companies like those on the STAR Market. Especially when there are actual order demands in both new energy vehicles and semiconductors, a single event may trigger expectation transmission across multiple industrial chains [1].
• The over 250% increase since this year proves the market’s trust in growth, but it also means a higher risk of pullback without support in the short term. Therefore, capital rotation and trading volume coordination are important variables to confirm the breakthrough [0].
• A Beta of only 0.52 indicates that the stock’s rise and fall depend more on internal catalysts than market fluctuations, leading to a slight disconnect between valuation and fundamentals. We need to continuously pay attention to order fulfillment and capacity release [0][1].

1. Valuation Contradiction Remains the Core Risk
   : High levels of PE 86x and P/S 20x mean that any slight underperformance in earnings may trigger short-term pullbacks, especially in the context of increased liquidity on the STAR Market [0].
2. Overbought Technical Indicators and Profit-Taking Pressure
   : RSI suggests it is approaching the overbought range, and the J value of KDJ is also approaching a high level. In the short term, it may retest the support at ¥115 or lower due to profit-taking or market sentiment fluctuations [0].
3. Cyclical Fluctuations in New Energy Vehicles and Semiconductors
   : Downstream cost reduction or peer competition may compress upstream order space. We need to observe whether the TE Connectivity award brings orders, changes in customer concentration, and disclosure of new contracts [1].
4. Opportunity Lies in Continuing to Seize Industry Prosperity
   : If there are more order contracts or Q4 profit elasticity exceeds expectations, the current market capitalization will be verified by performance; otherwise, valuation is a restrictive factor.
5. Time Sensitivity
   : In the short term (1-2 weeks), we need to pay attention to whether the ¥115 support is held. In the medium term (1-3 months), we need data to verify the sustainability of growth. In the long term, we need to see whether industry prosperity and the company’s technical moat are maintained.

• Time Background: At 2025-12-17 17:15:42 UTC+8, the stock was selected into the strong stock pool and hit a 52-week high, with trading volume and participation increasing simultaneously [0].
• Fundamentals: High R&D investment ratio, net profit margin of 22.95%, current ratio of 3.88, good financial quality, but ROE and cash return rate have not yet reached the industry’s highest level [0][1].
• Technical Aspects: MACD and KDJ both point to an upward trend, short-term target of ¥132.27, support level of ¥108.86; increased trading volume provides momentum for the breakthrough, but RSI warns of position control [0].
• Catalysts: The TE Connectivity award and industrial chain demand are short-term main lines. Social popularity and sector rotation have begun to materialize, but whether they bring quantitative orders remains to be confirmed by announcements [1][2].
• Conclusion: We need to track it with a cautiously optimistic attitude. In the short term, we can pay attention to the pullback window; in the medium and long term, we need to wait for further verification of performance and orders, and avoid ignoring potential fluctuations due to high valuation [0][1].
