Law enforcement authorities are looking into suspicious stock price fluctuations concerning Siwon School, a prominent online education company traded on the KOSDAQ. Actor Kim Soo Hyun’s agency, Gold Medalist, is also under investigation for possible involvement in the alleged stock manipulation.

Siwon School, well-known for its English education platform in South Korea, has been publicly traded on the KOSDAQ. The investigation was prompted by unusual stock price movements observed in recent years.

Stock data reveals that Siwon School's share price remained around 1,000 KRW before experiencing a sudden surge in July three years ago. Within nine months, the price soared to over 10,000 KRW but later dropped back to its initial levels due to a significant sell-off within two months.

The Financial Intelligence Unit (FIU) reported suspicions of market manipulation to the police, and the Korea Exchange (KRX) highlighted the stock for irregular trading activities. Specific accounts and their owners suspected of involvement in the manipulation are being scrutinized, with investigators tracing fund flows to ascertain any illicit gains from the scheme.

The ownership structure of Siwon School adds complexity to the situation, as more than half of the company's shares are held by a private investment partnership financed equally by two entities, including an entertainment agency.

The said agency, Gold Medalist, represents actor Kim Soo Hyun, who has denied any involvement in the stock trading activities under scrutiny. Financial regulators and entertainment industry experts are closely monitoring the investigation due to the notable individuals and potential legal implications involved.
