Tianjian Technology (002977) Daily Limit Analysis Report on December 5, 2025

Tianjian Technology (002977) is an aerospace enterprise in the national defense and military industry sector listed on the Shenzhen Main Board of A-shares [0]. On December 5, 2025, the company’s stock closed at the daily limit of 40.37 yuan, opening at 36.59 yuan with a 10.00% increase [0]. The daily limit was mainly driven by two core factors: 1) The national defense and military industry sector surged collectively in the afternoon, with nearly 20 stocks such as Xingtu Xinke (688081) and Guanglian Aviation (300900) hitting the daily limit or rising more than 10%, and sub-sectors like satellite navigation and commercial aerospace leading the gains [1][2]; 2) The successful launch of the Shijian-28 satellite by the Long March 7A rocket on December 1 continued to boost sentiment in the commercial aerospace sector [3]. The trading volume on that day was 764 million shares, 2.3 times the average trading volume of the past 5 days [0], indicating a significant increase in capital attention. The company’s net profit in the past 12 months was negative (-21.02%), with a price-to-earnings ratio of -289.71 times, lacking fundamental support [0].

1. Thematic Investment Driven
   : The daily limit was driven by sector themes (national defense and military industry, commercial aerospace) rather than the company’s own fundamental improvement; attention should be paid to the sustainability of sector hotspots [0].
2. Short-term Capital Inflow
   : A 2.3x increase in trading volume indicates high short-term capital participation, but it also increases the risk of correction during sector rotation [0].
3. Policy and Event Catalysis
   : Industry events such as the launch of the Long March 7A rocket have a significant impact on the sentiment of the commercial aerospace sector, reflecting the market’s high sensitivity to policy and technological progress in related fields [3].

• Main Risks
  : Lack of fundamental support (negative net profit growth, high valuation) [0]; the national defense and military industry sector is a thematic investment, highly affected by news, and may correct if the hotspot fades; the current price is close to the 52-week high of 49.00 yuan, with significant technical pressure [0].
• Potential Opportunities
  : If the national defense and military industry and commercial aerospace sectors continue to strengthen, the company’s stock may rise further driven by sentiment; breaking through the 49.00 yuan resistance level may open up new upside space.

Tianjian Technology (002977) hit the daily limit on December 5, 2025, driven by the surge in the national defense and military industry sector and the rising popularity of the commercial aerospace concept, with trading volume increasing by 2.3 times that day. The company’s fundamentals are weak, but short-term market sentiment is positive. Attention should be paid to the support level of 36.70 yuan (closing price on December 4) and resistance level of 49.00 yuan (52-week high), and be alert to the risks of sector rotation and technical pressure.
