TL;DR
Prosecutors raided securities firms including KB Securities, NH Investment & Securities, and Kyobo Securities over allegations of stock price manipulation involving DI Dongil. The case involves around 100 billion won and is the first major action under a new joint response team targeting unfair trading.
Prosecutors raided the headquarters of KB Securities, NH Investment & Securities, and Kyobo Securities on June 19, 2024, over suspicions of violating the Capital Markets Act in a 100 billion won stock manipulation scheme involving DI Dongil. These actions mark an intensification of investigations into alleged market abuse linked to a major stock price rigging case.
The Seoul Southern District Prosecutors’ Office, led by Chief Prosecutor Shin Donghwan, conducted the raids as part of a broader investigation into a scheme that allegedly manipulated DI Dongil’s stock price through coordinated efforts by financial experts, minority shareholder activists, and related corporations. The case originally surfaced after the Financial Services Commission’s Securities and Futures Commission filed a complaint in March, accusing 11 individuals—including wealthy investors and financial employees—and four corporations of orchestrating the scheme.
According to authorities, the suspects pressured DI Dongil’s management into signing a trust contract to acquire its own shares, falsely claiming to support minority shareholder activism. They then managed the stock’s trading volume to attract investors, with buy orders representing about one-third of the total market volume for DI Dongil at that time. This case is notable as the first major stock manipulation case handled by a newly formed joint response team, established after President Lee Jae-myung emphasized cracking down on unfair trading practices.
Previous searches and seizures were conducted on May 28 at NH Investment & Securities and DI Dongil, indicating ongoing efforts to gather evidence and dismantle the alleged scheme.
Implications of the Market Manipulation Investigation
This investigation highlights a significant effort by authorities to crack down on large-scale stock price manipulation, which can distort market integrity and harm investor confidence. The case involving DI Dongil, with alleged manipulation of around 100 billion won, underscores the potential scale of illegal trading practices and the government’s commitment to enforcing fair market rules. The raids on major securities firms suggest increased scrutiny on financial institutions and may lead to broader reforms or regulatory actions to prevent similar schemes in the future.

Background of the DI Dongil Stock Manipulation Case
The case originated after allegations surfaced that a group of wealthy investors, financial professionals, and minority shareholder activists manipulated DI Dongil’s stock price through coordinated trading and pressure tactics. The scheme reportedly involved mobilizing corporate funds and loans to influence the stock, with suspects allegedly pressuring management into signing a trust contract to buy back shares, under the guise of minority shareholder activism.
This case gained attention as it is the first major stock manipulation case handled by the newly established joint response team, created following President Lee Jae-myung’s directive to eradicate unfair trading practices. Prior to the raids, authorities had already conducted searches on May 28 at related firms, indicating an escalating investigation.
