Korean brokerages to offer near-24-hour US stock trading from Dec. 6

What happened: South Korean brokerages will offer near-24-hour US stock trading from Dec. 6, combining Nasdaq's expanded 23-hour schedule with an extra hour through Blue Ocean. Key numbers: Nasdaq's 23-hour session starts 9 p.m. Eastern Time on Sunday, Dec. 6 (11 a.m. KST Monday, Dec. 7). Korean investors' net US stock purchases were $2.20 billion from Nov. Why it matters: All domestic brokerages will support the schedule from day one, while firms in Japan, Taiwan, China, Europe and Southeast Asia are more cautious. Analysts say Nasdaq's session will become a direct competitor to the Kospi.
