Korean Stocks Recover Amid Counterbalancing of Foreign Investor Selling by Retail Traders

South Korean Stocks Rebound as Local Investors Counter Foreign Selling

South Korean stocks rapidly erased losses on Wednesday as local retail investors bought into a wave of selling by foreign funds. The Kospi, South Korea's main stock market index, rose 0.3%, reversing an early decline of as much as 3.2%. This reversal was largely driven by the buying activity of local institutional and retail investors, who have been compensating for the significant selling by foreign funds.

Samsung Electronics Co. pared most of its drop, after briefly plunging as much as 6.1% on its failure to reach a wage agreement with its biggest labor union. However, the company's shares have been a major contributor to the country's stock market rally, with the Korean memory makers' shares up more than 100% each so far in 2026.

A comparison of the year-to-date performance of the Kospi and other major stock markets is as follows:

The Korean memory makers' shares have been driven by the "AI hardware thesis" that drove the Kospi's record run. However, this thesis is now accompanied by execution risk on the supply side, which is a harder position to hold with conviction. Foreign funds have sold more than $45 billion worth of Kospi stocks so far this year, but buying by local institutional and retail investors has compensated.

Morgan Stanley analysts, including Joon Seok, raised their 12-month Kospi target to 8,500 from 6,500 on Wednesday, citing structural stories including reform as a reason for further upside. While there are external uncertainties such as the ripple effects from the Middle East situation, the analysts believe that the Kospi should be resilient.
