Yuanjie Technology (688498) Strong Performance: Analysis of Reasons, Support, and Sustainability

Yuanjie Technology (688498), a STAR Market semiconductor enterprise, entered the strong stock pool on December 8, 2025. Its strong performance mainly comes from three aspects:

1. Sector Driving Effect
   : The semiconductor sector has been strong recently; demand in the optical communication chip field continues to grow driven by 5G, data centers and AI applications [0];
2. Technical Breakthrough
   : The share price broke through the 60-day high to about 605 yuan intraday, attracting attention from technical investors [0];
3. Industry Position Support
   : As a leading domestic optical chip supplier, the company benefits from the domestic substitution trend and high-growth dividends of the industry [0].

Technically, the current support level is around 550 yuan, and the short-term resistance level is about 620 yuan [0]. Fundamentally, optical chips are a high-growth segment in the semiconductor industry with broad domestic substitution space, and the company has long-term growth potential.

1. Industrial Chain Linkage Effect
   : The explosion of data traffic brought by AI applications promotes the construction of data centers and 5G infrastructure, which in turn drives demand for optical chips, forming a positive industrial chain cycle of “AI - Infrastructure - Optical Chips” [0];
2. Long-term Logic of Domestic Substitution
   : Supported by domestic semiconductor self-reliance policies and coupled with international supply chain uncertainties, Yuanjie Technology, as a domestic optical chip leader, is expected to continue to benefit from the domestic substitution process [0].

• Risks
  : Semiconductor industry valuations are generally high, and the company needs sustained performance growth to support the current share price [0]; Competition among domestic and foreign optical chip manufacturers is fierce, and it is necessary to maintain technological leadership [0]; The sector is highly volatile, and short-term correction risks need to be vigilant [0].
• Opportunities
  : The optical communication chip industry is in a high-growth period, with strong demand from downstream applications such as AI and 5G [0]; The domestic substitution space is broad, and the company has a first-mover advantage as a leading enterprise [0].

Yuanjie Technology (688498) entered the strong stock pool due to semiconductor sector drive, technical breakthrough and domestic substitution logic, with current share price around 605 yuan. It has good technical support and benefits from industry high growth and domestic substitution fundamentally. It is necessary to pay attention to valuation risks and industry fluctuations, while focusing on the long-term development trend of the optical chip industry.
