Tongyu Communication (002792) Limit-Up Reason and Trend Analysis

Tongyu Communication (002792) is a communication equipment manufacturing enterprise. It hit the limit-up on December 15, 2025, with a closing price of 32.01 yuan, an increase of 10%, and a trading volume of 101 million shares on the day, far exceeding the recent average of 38.68 million shares [0]. Currently, the stock price is close to the 52-week high of 33.00 yuan, with a technical support level of 24.74 yuan and a resistance level of 33.04 yuan [0].

The limit-up catalyst: No company-specific positive news was found. It is speculated to be mainly driven by the industry policy of the Ministry of Industry and Information Technology to extend 5G and fiber optic networks to remote areas by the end of 2025 [1], combined with short-term speculative momentum. Technical indicators show that RSI is in the overbought range, and the KDJ indicator shows a bearish signal, implying short-term correction risk [0]. In addition, the company’s P/E ratio is as high as 1067-1107 times, with significant valuation pressure [0].

1. The limit-up lacks fundamental support from the company, mainly relying on industry policies and short-term speculative sentiment, so the sustainability of the rise is questionable.
2. The stock price is close to the 52-week high, and selling pressure near the resistance level may increase.
3. The extremely high P/E ratio reflects overheated market sentiment, with insufficient long-term value support.

• High valuation: P/E ratio exceeds 1000 times, deviating significantly from fundamentals, with high short-term correction risk [0].
• Technical overbought: Both RSI and KDJ indicators show overbought signals, which are often accompanied by short-term adjustments historically [0].
• Lack of company-specific positive news: The limit-up is driven by industry policies; if the policy implementation progress is less than expected, the stock price may fall back [1].

• Long-term policy dividends from 5G expansion in the communication industry: The Ministry of Industry and Information Technology’s network extension plan is expected to drive growth in demand for communication equipment [1].
• Short-term breakthrough potential: If trading volume continues to expand and breaks through the 52-week high of 33.04 yuan, it may open up further upside space [0].

Tongyu Communication’s limit-up is driven by both communication industry policies and short-term market momentum. Technical overbought and high valuation indicate short-term risks, while long-term industry policy dividends provide potential opportunities. Investors need to pay attention to changes in the company’s fundamentals, policy implementation progress, and the performance of trading volume and resistance levels.
