The value of South Korea's listed shares owned by foreign investors has climbed more than 10 percent this year as they loaded up on large caps, data showed Tuesday.

Offshore investors held 464.1 trillion won worth of shares traded on the main bourse and secondary KOSDAQ market as of last Wednesday, up 10.3 percent from end-2015 and taking up 30.56 percent of the total market capitalization, according to the data by the Korea Exchange.

The percentage represents a 1.42 percentage point increase from the end of last year.

The gain was led by foreigners' massive purchase of large-cap issues. Foreign investors owned 38.14 percent of large caps listed on the main KOSPI market, up 0.86 percentage point from the end of 2015.

The data also showed offshore investors buying a net 8.87 trillion won ($8.09 billion) on the main market this year, with their net buying reaching a yearly high of slightly over 4 trillion won in July.

South Korea's No. 1 cosmetics maker AmorePacific Corp. was the top buy among foreign investors with their net buying reaching 951.6 billion won.
