Samsung Electronics and Hynix Stock Price "No Big Shock" Despite 'HBM Bad News'

Despite the U.S. government's announcement of high bandwidth memory, HBM export controls to China, shares of Samsung Electronics and SK Hynix were not hit hard.

In the stock market, SK hynix rose 3.84 percent to close at 164,900 won, while Samsung Electronics rose to 54,400 won in the session and fell at the end of the session to close at 53,600 won, the same as the previous session's close.

Analysts say the market accepted that the announcement rather eased uncertainty because the Biden administration's control of HBM exports had already been reflected in stock prices.

The KOSPI and KOSDAQ indexes also rose.

The KOSPI rose 1.86 percent to 2,500.1, amid net buying by foreigners and institutions, and the tech-heavy KOSDAQ index also gained 2.21 percent to 690.80, led by net buying by foreigners.

The won-dollar exchange rate rose to 1,407 won as of 8:25 and then fell, trading in the early 1,400 won range.
