According to industry sources, Chey purchased 3.62 trillion won worth of SK Hynix shares, equivalent to 4.8 billion won, on July 30.

Under the insider trading pre-disclosure system, executives or major shareholders of listed companies must disclose their trading plans 30 days in advance if they intend to buy or sell shares that exceed 1% of the total issued shares or 5 billion won in transaction value over the past six months and the upcoming trading period. The obligation to disclose is waived if the transaction volume is less than 1% of the total issued shares and the transaction value is below 5 billion won.

This requirement to aggregate transaction amounts over the past six months is intended to prevent so-called "split trading" to evade disclosure obligations.

As a result, the amount Chey can purchase without prior disclosure in the next six months is limited to 5 billion won, excluding the current purchase. To buy more than this amount, he would need to disclose a trading plan if the cumulative transaction value exceeds 5 billion won, and the actual purchase would be possible at least 30 days after the disclosure.

This transaction represents the maximum scope that can be executed without separate prior disclosure under the current pre-disclosure system. It is seen as a prompt way to convey his commitment to responsible management while adhering to existing procedures.

Chey reportedly decided to make this stock purchase based on his belief in the value of the semiconductor business and his assessment that SK Hynix's stock price is currently undervalued.

According to disclosures, SK Square is currently the largest shareholder of SK Hynix, holding a 20% stake. Besides Chey’s 3,620 shares, Kwak Noh-jung, CEO of Hynix, owns 14,312 shares, and Cha Sun-yong, head of the Future Technology Research Institute, holds 6,834 shares.
