Institutions and foreign investors offloaded a net combined 986 billion won worth of stocks, offsetting retail investors' selling valued at 956 billion won.

As the latest jobs data, out Wednesday, showed US private job growth slowed in March, investors weighed what the weaker-than-expected numbers say about the health of the broader economy.
