YesTee will become the largest shareholder by securing up to 31.82% stake in Power Technics through this investment. It is expected to prepare for mass production with the development of power semiconductor components as a subsidy to expand business area into power semiconductor parts business. For the first time since the beginning of last year, YesTi has been investing in Power Technology, a company that manufactures and manu- factures manpower, and has been in the process of designing, manufacturing and selling SiC (Silicon Carbide) power semiconductor devices for the first time in Korea . Currently, SiC power semiconductors have been built in a batch production system, and on the 19th, the ceremony for mass production was held at the Pohang Nano Convergence Technology Institute. Unlike conventional power semiconductors, SiC power semiconductors have low energy loss and high energy efficiency, and are currently being installed in industrial renewable energy infrastructures and electric vehicles. If power technology grows in this market dominated by developed countries such as Germany and the United States, it will likely lead to growth of Forester through considerable import substitution effect.

The technical analysis report was prepared based on the "Technology Analysis Model for Investment" jointly developed by KIAT and KIBO at the end of 2015. The existing technology credit evaluation (TCB) is centered on corporate stability, bad credit risk prediction, and technology-secured bank loans, but it is focused on investment indicators such as growth and profitability that are used in actual investment decisions.
The K-OTC is the only institutional stock market in the nation that opens and operates the KTO. The K-OTC companies that applied for this project and published technical analysis reports for investment are the five companies such as Sinclair, Arribio, Aha Information Communication, Pkeet Valve and Hyundai Infracore.
The three agencies plan to help the report be widely used for K-OTC corporate investment information and fundraising. Next year, we will expand support for unlisted companies participating in K-OTC PRO, a specialized investor market.

The number of ant stock investors who are affected by the stock market has been increasing.
According to the Korea Exchange, five stocks were delisted from the KOSDAQ market in September 2011. When these items are withdrawn, most of the damage goes to the ants. This is because ant stock investors bought stocks of stocks traded by foreigners and institutions that detected early warning signs of the company. In addition, ants' speculative investment (speculative investment without systematic analysis or accurate information) on speculative stocks is pointed to cause damage.
A KCCI official said, "There are many excellent companies in the KOSDAQ market. It is safest to invest in a company where management is transparent and performance is backed up. "We are encouraging companies to inform investors of the correct internal situation."
