This includes cases where chairmen directly hold shares in listed companies, as well as cases where they indirectly hold stakes in listed group affiliates through unlisted companies.

Unlisted companies were limited to those where the chairman holds more than 50% of the company's shares, and preferred stocks were also included in the survey scope. The second-quarter stock valuation was calculated based on closing prices as of March 31 and June 30.

According to the survey results, Lee Jae-yong's stock valuation increased from 30 trillion 941.4 billion won at the end of March to 59 trillion 187.8 billion won at the end of June, a rise of 28 trillion 246.3 billion won, securing first place in terms of increase amount. The growth rate was 91.3%.
