KOSPI Reverses a 4.1% Fall to Close Higher as SK Hynix Jumps 4.4%
South Korea's KOSPI completed a remarkable intraday reversal on Friday. After falling as much as 4.12% to 5,305.98, the index finished at 5,550.30, up 0.30% from Thursday's close. SK hynix ended 4.42% higher and Samsung Electronics gained 0.47%, with both chipmakers closing at their session highs in the delayed market record.
Japan also recovered sharply, although the Nikkei 225 still closed 0.34% lower at 62,693.16. The index had been down as much as 2.30% and SoftBank had fallen almost 8% from Thursday's close at its low before finishing only 0.67% lower.
The close validates the stabilisation scenario in our late-morning KOSPI analysis, but it does not erase the broader volatility. Brent remained above $114, gold stayed below its reference close and the previous US session's Nasdaq decline still shapes the next test.

Korea turns an opening liquidation into a positive close
The KOSPI rose 4.60% from its session low to the close and ended at the high of the day. The index also reclaimed Thursday's 5,533.77 close, satisfying the first confirmation level identified in the previous update.
The internal recovery was strongest in semiconductors. SK hynix climbed from ₩1,171,000 at the low to ₩1,277,000, a 9.05% recovery from the trough and a 4.42% daily gain. Samsung moved from ₩203,500 to ₩215,500, recovering 5.90% from the low and closing 0.47% higher.
That matters because the KOSPI is heavily influenced by these two stocks. A positive close in both gives the reversal more weight than an index rebound caused by unrelated defensive shares. It also shows how dangerous it would have been to treat the early 4% decline as a completed daily breakdown before the close.
However, one positive day does not rebuild the broader trend. Thursday's KOSPI close was already 3.52% below Wednesday, and the index remains exposed to global AI-investment concerns, semiconductor volatility and higher energy costs.
Nikkei recovers more than 1,200 points from the low
The Nikkei finished 214.68 points lower at 62,693.16, a 0.34% decline. From its 61,462.61 session low, it recovered 1,230.55 points, or roughly 2.00%.
SoftBank's path was similarly dramatic. The share fell to ¥3,962, nearly 8% below Thursday's close, before ending at ¥4,276, only 0.67% lower. Even so, the Nikkei did not close above 62,907.84 and therefore stopped short of the full reversal achieved in Korea.
Japan's September headline and fresh-food-excluding CPI both rose 2.1% year on year, while inflation excluding fresh food and energy reached 2.4%. The figures keep the 29–30 October Bank of Japan meeting relevant. USD/JPY near 157.06 in the later snapshot showed a modestly weaker yen against the new-session reference.
Oil holds its advance; gold remains below confirmation
Brent traded near $114.14, 0.86% above its reference, and WTI near $100.57, up 1.11%. Both remained below their earlier sampled highs near $114.66 and $100.98, but WTI's hold above $100 was stronger than the first failed attempt earlier in the session.
Gold was near $4,030.10, down 0.75% from the $4,060.40 reference. It had recovered from the earlier $4,000.90 low but had not reclaimed $4,060. That keeps gold in a recovery attempt rather than a confirmed reversal.
The oil-gold split matters for risk assets. High oil can sustain inflation concerns, while weak gold can reflect liquidity pressure or a firmer dollar. No single relationship should be treated as automatic; the next daily closes matter more than an intraday narrative.
US futures and Bitcoin improve after the Asia close
Nasdaq-100 futures rose 0.27% to 29,220.50 and S&P 500 futures edged 0.04% higher. Dow futures remained 0.18% lower, so the US signal was mixed but better than an hour earlier.
Bitcoin was 0.53% higher near $81,748 and close to the session's $81,913 high. A break above that high and acceptance above $82,000 would strengthen the risk-recovery signal. A return below $81,012 would invalidate it.
The Money Man View: next one to three sessions
Base case: the Asia close confirms that early forced selling was absorbed, especially in Korean semiconductors. The next phase is a follow-through test. A reversal day becomes more valuable if the next session holds above the reclaimed levels; it becomes a warning of unstable positioning if the entire move is quickly lost.
Bullish scenario: KOSPI holds above 5,534 and breaks 5,550, while SK hynix stays above ₩1,223,000 and Samsung above ₩214,500. Confirmation would strengthen if the Nikkei reclaims 62,908, Nasdaq-100 futures hold above 29,220 and Bitcoin breaks $81,913.
Bearish scenario: KOSPI falls back below 5,534 and then loses 5,400, while both chipmakers surrender their reclaimed previous closes. A Nikkei break below 61,463, gold below $4,000 or Nasdaq-100 futures below 29,105 would indicate renewed pressure.
What invalidates the stabilisation view: a fresh KOSPI break below 5,306 would invalidate the idea that Friday's close established durable support. A smaller warning would be a next-session gap below 5,400 without recovery.
What to monitor next
- KOSPI follow-through above 5,550 and support at 5,534.
- SK hynix holding ₩1,223,000 and Samsung holding ₩214,500.
- Nikkei reclaiming 62,908 after closing 0.34% lower.
- Brent $114.66 and WTI $100.98 as breakout confirmation levels.
- Gold's $4,000 support and $4,060 recovery threshold.
- Nasdaq-100 futures at 29,220 and Bitcoin at $81,913–$82,000.
Sources and methodology
The session's earlier global context and intraday readings were checked against the Associated Press Asia market report. Japan's inflation figures come from the Statistics Bureau of Japan's official September CPI release.
Closing prices and session ranges were sampled from Yahoo Finance one-minute chart data and closing metadata for the KOSPI, Nikkei 225, Samsung Electronics, SK hynix and SoftBank. Cross-asset prices came from the same delayed data source.
