Analysis of Kangst (300445) Limit-Up Trend

Kangst (300445) hit the limit-up at 25.61 yuan on December 12, 2025, with a 20.01% increase. The limit-up trend was driven by multiple factors:

1. Sector Linkage and Concept Popularity
   : On that day, the sensor concept sector rose by 1.74%, driving related stocks to be active, and Kangst benefited as a hot stock in the sector [1].
2. Fundamental Improvement
   : The company recently expanded into businesses such as electronic component manufacturing, software development, and sensor design, positioning sensors as an important future business line [2]; it also optimized its governance structure to improve decision-making efficiency [2]; in the third quarter of 2025, the international market grew by 21.5% year-on-year, the U.S. regional market growth rate turned from negative to positive, and the business showed a recovery trend [2].
3. Capital and Technical Support
   : The main force and hot money continued to flow in net in the two days before the limit-up (December 8 and December 11) [1][3]; the total turnover on the limit-up day was 547 million yuan, and the turnover rate increased significantly [2]; technically, the MACD indicator may form a golden cross, and the stock price broke through an important resistance level, attracting technical investors [2].

1. Business Transformation and Market Expectations
   : The company’s expansion into the sensor field aligns with current market hotspots in the technology sector, successfully stimulating investors’ expectations for its future growth.
2. Synergy of Internal and External Factors
   : Domestic sector popularity synergizes with internal improvements such as the company’s international business recovery and governance structure optimization, jointly driving the stock price up.
3. Capital Structure and Short-Term Trend
   : The proportion of hot money is relatively large (accounting for 8.98% of total turnover on December 11) [1], indicating that short-term speculative funds have a significant impact on the stock price, and attention should be paid to the sustainability of subsequent funds.

• Risks
  : Short-term fluctuations may increase after the limit-up [0]; the actual effect and profit level improvement after business expansion need continuous verification [2]; after a large increase in stock price, overvaluation risks are worth vigilance [1].
• Opportunities
  : The sensor industry has broad development prospects; if the company’s business transformation can proceed smoothly, it is expected to benefit from industry growth in the long term; after governance structure optimization, decision-making efficiency is improved, which may accelerate the business expansion process.

The limit-up trend of Kangst (300445) is the result of the combined effect of sector popularity, company fundamental improvement, capital inflow, and technical pattern breakthrough. Currently, attention should be paid to short-term capital continuity, business expansion effect, and valuation level to judge the stock price trend more comprehensively.
