Younger and financially inactive family members of corporate owners hold shares worth some 390 billion won ($363 million) in listed firms, with a 9-month-old baby holding shares worth 800 million won, data showed on Thursday.

According to the data compiled by research firm CEOscore, some 230 family members of owners of 1,769 listed firms, ages 19 or below, held a combined 391 billion won in shares as of Tuesday.

The data also showed a total of 7,990 corporate owners and their family members each held shares worth at least 100 million won.

Of the tallied, a baby born in May last year owned shares worth 790 million won in Kyung In Synthetic Co., a textile firm.

Among the minor-aged family members, two male heirs of GS Group, a retail and oil refining conglomerate, topped the list. The boys, aged 13 and 10, held 39.5 billion won and 16.1 billion won worth of shares each in GS Holdings Co.

A daughter of the president of Seoul Semiconductor was the richest scion among those aged below 30, with 231 billion won worth of stocks, followed by a daughter of Suh Kyung-bae, who heads South Korea’s top cosmetics manufacturer Amore Pacific Corp., with 53.8 billion won worth of shares.

The researcher said its latest survey showed that most of the young and rich either were given or had inherited the stocks from their parents or relatives. If this trend continues, the list of stock-rich children will continue to grow, it said.

The oldest stock-rich person was Kim Shin-kwon, honorary chairman of Handok, a healthcare firm. Kim, aged 99, held stocks worth 9.6 billion won, the data showed. (Yonhap)
