Buy Sidecars Triggered in Both Markets…Sharp Rebound on Foreign Buying

Buy sidecars were triggered on KOSPI and KOSDAQ early in trading on November 10. KOSPI traded around 5,240 and KOSDAQ around 663, up in the 4% and 3% ranges, respectively. KOSPI gave back part of its intraday gains, forming a candle with a long upper wick, while KOSDAQ maintained its upward trend. Foreign investors supported the rebound with net purchases in the 200 billion won range in the exchange’s cash market and in the 340 billion won range in the futures market. The won-dollar exchange rate stood at 1,346 won, up 6 won and 90 jeon from the previous day. After recent sharp declines had heightened volatility, the pause in the sell-off and subsequent rebound provided some relief to the market. The host said buy sidecars appeared to have been triggered more than 20 times on KOSDAQ and that circuit breakers had also been triggered more often this year than in any previous year. The explanation was that greater volatility widens the range of possible future outcomes investors must anticipate, making investment decisions more difficult. Despite the rebound, intraday trading remained unsettled, with gains narrowing in response to changes in Nasdaq futures and market flows.

KOSPI Rebounds After Falling Below 5,000… Foreign Spot Selling Continues

KOSPI fell below 5,000 in early trading, sliding to around 4,990, but later recouped its losses to stand at 5,144 points, up 1.5%. At one point during the session, gains exceeded 2%. KOSDAQ rose 1.8% to 656 points. Foreign investors continued to sell in the spot market. They sold more than KRW 600 billion on the Korea Exchange and more than KRW 100 billion on KOSDAQ, while buying futures. After net purchases of more than KRW 1 trillion in futures late Friday, foreign investors bought nearly KRW 600 billion during the session on Monday. Although markets rebounded after the sharp decline, analysts said the recovery was weak relative to the losses and lacked a clear catalyst. Taiwan's TAIEX rose around 5.8% on expectations of intervention by its National Stabilization Fund, while Japan's Nikkei gained more than 3.3%. The Shanghai Composite rose more than 0.4%. This week’s schedule includes TSMC’s October revenue report, CoreWeave’s earnings, the expiration of Korean options, and a U.S. 30-year Treasury auction. MSCI’s semiannual review is also due, with any changes taking effect on November 30.

KOSPI Falls Below 5,000 Intraday, Then Cuts Losses Amid Foreign Selling

The KOSPI plunged by as much as about 8% early in the session, falling below 5,000, while Samsung Electronics briefly dropped to KRW 175,000. It later pared losses on bargain buying and at one point recovered above 5,100, but weakened Asian markets in the afternoon sent the KOSPI back down to the 5,070 level, a decline of 5.8%. The KOSDAQ also fell more than 7% intraday before trimming losses, but traded around 647 in the afternoon, down 4.5%. Foreign investors recorded net sales of more than KRW 1 trillion on the KOSPI, with the amount later rising to around KRW 1.2 trillion. Foreign selling also continued on the KOSDAQ, while foreign investors were observed turning net buyers in the futures market. Institutional buying was concentrated among financial investment firms, and pension funds also shifted to buying during the session. Retail investors bought cash equities, but reduced the scale of their purchases from early in the session. The won-dollar exchange rate rose by about KRW 2.40 from the previous day to around KRW 1,359. Volatility in the KOSPI was severe enough to trigger a circuit breaker early in the session, while bargain buying helped recover some of the losses during ongoing trade. However, major Asian markets including Japan, Taiwan and Shanghai weakened again in the afternoon, limiting the domestic market's recovery.
