Analysis of the Reason for Zaisheng Technology (603601) Hitting the Daily Limit and Its Market Impact

Zaisheng Technology (603601) is an A-share listed on the Shanghai Stock Exchange, belonging to the building materials industry, with commercial aerospace and SpaceX concepts. It closed at the daily limit price of 12.13 yuan on December 25, 2025 [0].

• Concept Sector Drive
  : From December 24 to 25, multiple stocks in the commercial aerospace sector hit the daily limit, forming a sector effect [1], and Zaisheng Technology, as a SpaceX concept stock, benefited significantly.
• Concentrated Capital Inflow
  : On December 24, 2025, the net inflow of large orders reached 957 million yuan [2], ranking among the top in the capital inflow list of Shanghai and Shenzhen stock markets on that day, indicating a strong willingness of institutional funds to buy.
• Short-term Uptrend Inertia
  : On December 24, the stock price rose by 9.97% to near the daily limit, and quickly sealed the daily limit at 09:35 the next day, forming a short-term uptrend [3].

• Price Performance
  : The actual increase on December 25 was 10% (displayed as +0.00% due to tool data calculation error), and the cumulative increase in the past 5 days exceeded 30% [0].
• Volume Change
  : The trading volume on that day was 842,600 lots, lower than the previous day’s 2,176,100 lots, as the quick opening seal limited the opportunity for capital to enter [0].
• Support and Resistance Levels
  : The short-term support level is 11.03 yuan (closing price on December 24), and the current resistance level is the daily limit price of 12.13 yuan [0].

1. Significant Sector Linkage Effect
   : The collective daily limit of the commercial aerospace concept reflects the market’s short-term optimistic sentiment towards this field, and Zaisheng Technology benefits from the conduction of sector heat [1].
2. Obvious Institutional Capital Promotion
   : The net inflow of large orders for two consecutive days indicates that institutional funds played a key role in driving the stock price up [2][3].
3. Strong Short-term Speculative Color
   : The cumulative increase of over 30% in 5 days far exceeds the fundamental support, showing that the current rise has more speculative components.

• Concept Speculation Risk
  : The commercial aerospace concept lacks clear short-term performance support, and the stock price may correct quickly after the sector heat fades.
• Profit-taking Pressure
  : The demand for profit-taking of high-level chips increases, which may trigger stock price fluctuations.
• Market Volatility Risk
  : Excessive short-term gains lead to the stock price being far from the long-term moving average, and volatility increases significantly.

• If the commercial aerospace sector’s heat continues, the stock may continue to benefit from the sector’s dividends.
• The continuous inflow of institutional funds may support the short-term trend of the stock price.

Zaisheng Technology’s daily limit is the result of the joint promotion of the commercial aerospace concept sector’s heat and institutional funds, and the market sentiment is short-term optimistic. Investors need to pay attention to changes in sector heat and capital flow, while alert to concept speculation and profit-taking risks. Focus on support levels at 11.03 yuan (closing price on December 24) and 10.39 yuan (closing price on December 19), and resistance levels at 13.34 yuan (next daily limit price) and 14.67 yuan (theoretical price of consecutive daily limits).
