Funds investing in special overseas assets, excluding securities and property, had a combined 16.86 trillion won under their management, up a whopping 72.9 percent from a year ago.
The total net worth of property-focused investment funds jumped 55.9 percent over the cited period to 26.79 trillion won.

Experts attributed the jump in the net worth of overseas investment funds to increased interest by local institutions and big retail investors in overseas assets that produce relative higher returns than domestic stocks.
According to the data, the combined value of domestic stock-type funds fell to 52.98 trillion won as of Wednesday from 55.94 trillion won a year ago, despite the record pace of the stock market.
