The driving event is that China plans to strongly support the development of the third generation semiconductor industry.
So the point is, what is the third generation semiconductor?
The first generation material is silicon (Si), and it is generally understood that Silicon Valley is the industrial park of the first generation semiconductor.
The second generation material is gallium arsenide (GaAs), which was born for the 4G era. At present, the materials of most communication equipment.
At present, the third generation materials are relatively mature, such as silicon carbide (SiC) and gallium nitride (GaN), which will be standard in the future 5G era.
It is a key core material and electronic component to support the independent innovation, development, transformation and upgrading of new generation mobile communication, new energy vehicles, high-speed trains, energy Internet and other industries.
Ganzhao Optoelectronics itself does not produce gallium nitride, and only one shareholding company produces gallium nitride. Gallium nitride is just one of the materials for the company to produce LED chips and epitaxial wafers.
On Friday morning, the second board reduced its holdings, and the largest single in the session was 75 million shares. Short-term hot money intervention is profitable. If it opens sharply higher on Monday, it is necessary to prevent selling pressure.
(risk warning: when the market weakens, high stocks are also easy to become the primary target of shorting. Non-professional speculators, without high risk control ability, just look)
