10-session rally puts index near technical bull market
I think the market overshot to the downside during the unwinding of leveraged positions, and the current rebound is a natural one as flow stabilized. That said, I think it will be difficult for the market to sustain a continued rally until we see some stabilization in the AI narrative and US interest rates.
Commenting on Korea's rebound from July rout
Analysis
For investors tracking global equity rotations, the Kospi's 22% rebound from its July 30 low in just ten sessions is a stark reversal after July's 22% collapse — the index's worst month since the global financial crisis. The rebound is being fueled by returning AI-hardware demand and stabilizing leverage, but the more than $100 billion in foreign outflows this year suggests institutional conviction has yet to return.
South Korean equities staged a dramatic reversal over the first half of August, with the benchmark Kospi gaining as much as 4.8% on Thursday, August 13, extending its rebound from the July 30 low to roughly 22% in just ten sessions. The rally puts the index on the cusp of a technical bull market, defined as a 20% rise from a recent low, and marks a sharp departure from July's historic rout, when the index fell 22% in its worst month since the global financial crisis. The immediate catalysts are not idiosyncratic to Korea but reflect a broader revival of the global artificial-intelligence trade, led by heavyweight memory-chip makers Samsung Electronics and SK Hynix, both of which jumped more than 5% on the day.

The July collapse was a stress event in the retail-dominated Korean market. Forced liquidation of leveraged bets on chipmakers triggered trading halts and wiped out billions of dollars in retail wealth. In response, Korean authorities imposed curbs on single-stock leveraged exchange-traded funds, while investors began reducing margin debt. Those measures, along with a stabilization in flows, removed some of the mechanical selling pressure that had amplified the drawdown. Kang DaeKwun, chief executive officer at Life Asset Management, described the rebound as "a natural one as flow stabilized," noting that the market "overshot to the downside during the unwinding of leveraged positions." His caveat was equally important: he said it would be difficult to sustain a continued rally until the AI narrative and US interest rates stabilize.
The macro backdrop also turned favorable in mid-August. A subdued US inflation report released on Wednesday, August 12, eased concerns about imminent Federal Reserve interest-rate hikes and lent support to US-listed semiconductor peers, creating a positive feedback loop into Asian chip names. Expectations that Samsung Electronics and SK Hynix will soon announce shareholder-return plans have added a domestic corporate-governance tailwind, lifting sentiment in recent sessions.
What to Watch
Yet the recovery remains fragile and uneven. The Kospi is still up more than 60% year-to-date on a largely retail-driven rally, but it remains about 24% below its late-June peak. Foreign investors have been persistent net sellers, withdrawing more than $100 billion from Korean shares in 2026 as the market grew crowded and overheated. That divergence between local retail momentum and institutional foreign outflows is a structural vulnerability. If global risk appetite turns again, the same leverage dynamics that made the July plunge so violent could reassert themselves. Conversely, if Big Tech earnings continue to validate massive AI capital expenditure and Korean memory makers convert that demand into earnings and shareholder returns, the market could finally reclaim its June highs.
For global investors, the Kospi's round trip from euphoria to forced deleveraging to technical bull market in under two months is a case study in crowded positioning and policy intervention. The key question is whether the rebound reflects genuine improvement in semiconductor fundamentals or simply the unwinding of prior forced selling. The data point to a mix: AI demand signals remain strong, but valuation and flow indicators are stretched. The next test will come as Samsung and SK Hynix report detailed earnings and return plans, and as the Federal Reserve's rate path becomes clearer. Until then, the market's direction will remain sensitive to any headlines on US inflation, AI spending, or leveraged retail flows.

How we covered this story
Every story in our finance coverage is assembled from multiple primary sources, cross-referenced for factual consistency, and scored along three independent dimensions: sentiment, operational impact, and source-cluster confidence. Single-source rumors and unverifiable claims do not pass our editorial gate. When a story shows "Verified by N sources" with N≥2, the development is independently corroborated; when N=1, we mark it explicitly so readers can weigh the signal accordingly.
Impact scoring uses a 1-10 scale weighted toward regulatory, financial, and operational consequence rather than coverage volume. A topic that runs in every outlet but moves no real decisions ranks lower than a niche regulatory filing that reshapes how operators in the finance space have to behave. Read our full methodology for the scoring rubric, our glossary for term definitions, and our trends index for the longitudinal view across the beat.
Sources are only linked to a story once they clear our classification pipeline at a minimum 35 percent relevance threshold. According to that methodology, reviewed July 2026, this follows multi-source corroboration standards recommended by journalism research bodies such as the Reuters Institute for the Study of Journalism.
