Analysis of Strong Performance and Sustainability Judgment for Hengyu Xintong (300965)

Hengyu Xintong (300965) entered the strong stock pool on December 8, 2025, with a strong performance that day [0]. The core driving factor is the technical breakout with heavy volume: trading volume reached 5.25 million shares, 5.7 times higher than the previous day’s 922,400 shares, far exceeding the average volume of 1.2 million shares, accompanied by an 11.87% increase in stock price (closing price at 65.87 yuan) [0]. Technical indicators show: the upward trend is to be confirmed, with a buy signal appearing on December 8; resistance level at 69.00 yuan, target price at 71.88 yuan, support level at 59.30 yuan [0]. Fundamentally, the company belongs to the aerospace and defense industry, with good current ratio performance, but a high PE ratio of 118.94 times and ROE of only 2.69%, showing a contrast between profitability and valuation [0]. No recent public catalytic events were found in the news, which may be due to information disclosure restrictions in the military industry or pure technical momentum driving [0].

1. Strong technical signals but need to watch for overbought conditions: KDJ indicator is bullish, volume expansion supports upward movement [0], but RSI is in the overbought range; if subsequent volume fails to sustain, the risk of price correction rises.
2. Fundamental and technical divergence: High PE ratio and low ROE indicate that valuation may deviate from profit support [0]; need to pay attention to whether there are undisclosed industry or company-level catalytic factors (such as order finalization, technological breakthroughs, etc.).
3. Industry characteristics affect information transparency: The confidentiality attribute of the aerospace and defense industry may lead to delayed disclosure of catalysts, so subsequent announcements need to be closely tracked.

• Risk
  : High PE ratio brings valuation correction risk [0]; low ROE reflects insufficient profitability [0]; lack of public catalytic events may lead to unsustainable technical momentum.
• Opportunity
  : If volume continues to expand, the technical upward trend may extend to the target price of 71.88 yuan [0]; the long-term growth potential of the aerospace and defense industry may provide support.

Hengyu Xintong (300965)'s strong performance on December 8 was mainly driven by technical breakout with heavy volume [0]. Technical indicators show upward signals, but fundamentals have valuation and profitability pressures, and there are no public catalytic news [0]. Need to pay attention to volume changes, resistance level breakthroughs, and potential undisclosed industry developments, and carefully evaluate its sustainability.
