Analysis of Haozhijidian (300503) Strong Performance: Catalysts and Sustainability Judgment

Event background: On December 30, 2025 (UTC+8), Haozhijidian (300503) entered the market’s strong stock pool due to its recent strong performance. The core catalyst is the business layout announcement issued by the company on December 26, 2025, stating that it will actively expand into the robotics and commercial aerospace sectors. As of September 30, 2025, this business accounted for only about 1% of the main business revenue [1][2]. This announcement coincided with a general rise in the robotics concept sector, and capacity expansion plans of industry enterprises such as UBtech further strengthened the market’s attention to this theme [3].

Stock price performance: From December 22 to 29, 2025, the company’s stock price rose from $35.66 to $53.80, with a cumulative increase of 50.87%. Among them, it hit the daily limit on December 25 (+15.63%), rose sharply by 15.15% on December 26, and broke through the all-time high on December 29 with a daily increase of 19.50% [0]. Trading volume increased significantly synchronously: the trading volume on December 25 and 29 reached 52.45M and 75.95M respectively, far exceeding the previous average level of 15-25M, indicating a sudden rise in market attention and participation [0].

Technical analysis: The short-term trend shows an upward trend (to be confirmed), and a buy signal was issued on December 25, 2025; in terms of key prices, the support level is $39.47, the resistance level is $54.55, and the next target price is $57.55 [0]. The KDJ indicator shows a bullish market with a strong short-term trend, but the RSI indicator indicates an overbought risk [0].

Fundamental analysis: The company’s current market capitalization is $16.583 billion, PE is 134.11 times, far higher than the industry average; PB is 12.34 times, PS is 11.19 times, and the overall valuation is at a high level [0]. The core business is still traditional mechanical products, and the robotics and commercial aerospace businesses are in the layout stage, so future growth is uncertain [2].

1. Theme speculation dominates the market
   : The market reaction is seriously disconnected from the company’s current business contribution—the robotics and commercial aerospace business accounts for only 1%, but the market speculates based on future growth expectations, which conforms to the short-term market logic of “speculating on expectations” [1].
2. Technical and fundamental divergence
   : Short-term technical indicators show a strong trend, but high valuations (PE 134.11x [0]) and limited new business contributions mean that the stock price lacks solid fundamental support, so investors need to be vigilant against valuation bubble risks.
3. Market sentiment resonance-driven
   : The company’s announcement coincided with the market boom period of the robotics concept sector, and industry-wide positive news (such as UBtech’s capacity expansion [3]) amplified the stock’s increase.

• Valuation is too high: PE, PB, PS are all far higher than the industry average, and the risk of valuation bubble is large [0].
• Business uncertainty: The proportion of new businesses is extremely low, and whether they can grow rapidly in the future is unknown; the company has reminded investment risks in the stock price fluctuation announcement [2].
• Overbought callback: Technical indicators such as RSI indicate overbought, and there is short-term callback pressure [0].

• Layout in high-growth fields: Both robotics and commercial aerospace are high-growth tracks in the future. If the company can successfully expand its business, the long-term growth potential is considerable.
• Continuation of theme market: If the robotics concept sector remains popular, the stock may still have short-term upside space.

• Current price
  : $53.80 (closing price on December 29, 2025) [0].
