Kospi Enters a Bull Market, and Is Still 27% Below Its Record

TL;DR

• The Kospi closed at 6,813.34 on Thursday, August 13, up 3.56%, a fourth straight gain. That is 21.8% above the July 30 close of 5,593.71, which clears the 20% line and puts the index in a technical bull market.
• Chips did it. SK Hynix closed up 5.92% at ₩1,593,000 and Samsung Electronics up 4.89% at ₩268,000. Both ran higher intraday than they finished, so the closes are the numbers to quote.
• The index is still 27.4% below the June 19 record close of 9,385.59. Getting back needs another 37.8% from here. Bull market and deep drawdown are both true at once.
• The US listing moved first. SK Hynix's Nasdaq ADR, SKHY, closed up 9.01% at $154.41 on Wednesday, four hours before Seoul opened the session that produced the 5.92%.
• July was the worst month for Korean equities since 1997, down 22.19%. Two weeks later the same index is in a bull market. I would hold both facts before deciding this is a recovery.

Why Is the Kospi Up Today?

A revival in the global AI trade pushed Korean chipmakers higher, and the Kospi closed up 3.56% at 6,813.34 on Thursday, August 13. SK Hynix and Samsung Electronics are roughly a third of the index between them, so when memory rallies the benchmark has no choice.

The move crossed a threshold that gets written about: 20% up from a recent low is the conventional definition of a technical bull market, and the index cleared it. Against the July 30 close of 5,593.71 the rebound is 21.8%. Bloomberg measured it from the intraday low and got roughly 22% over ten sessions; Seoul Economic Daily used a July 30 low near 5,550 and got about 23%. All three bases clear 20%, which is why the label stuck regardless of which one a desk used.

Intraday the index was up more than 4%. It finished at 3.56%. If you see both figures today they are the same session at different hours.

The Board

Twenty percent off the low and twenty-seven percent off the high, on the same afternoon.

Twenty Percent Off a Low Is a Weaker Claim Than It Sounds

The bull-market label measures from the bottom. The drawdown measures from the top. Only one of those is where shareholders bought.

The Kospi's record close is 9,385.59, set on June 19, a figure this site has been working from since the July collapse. Thursday's 6,813.34 sits 27.4% under it. To close that gap the index needs another 37.8%, because a percentage fall and the percentage rise that reverses it are never the same number.

So an investor who bought the June high is down 27% and has just read that Korea is in a bull market. Both statements are arithmetic. My rule with the technical labels is to treat them as descriptions of momentum and nothing else, because a 20% bounce off a 40% hole is a real rally and it is also still a hole.

There is a sharper version of the same point inside the index. On July 31 SK Hynix closed limit-up at ₩1,718,000, the maximum daily move Korean rules permit. Thursday's ₩1,593,000 is 7.3% below that print, two weeks later, after the stock has supposedly led the market into a bull run. The biggest constituent has not made back its single best day.

What has genuinely changed is the direction of the memory story. July's rout ran on the fear that hyperscaler AI budgets were about to be cut. Since then Microsoft, Meta and the rest have raised capex, Cisco guided fiscal 2027 AI infrastructure revenue to $7.5 billion, and memory pricing has stayed tight. The bear case that produced the crash has been contradicted by the buyers' own guidance. That is a better reason to be constructive than the 20% threshold is.

The Nasdaq Listing Moved First

Here is the piece of Thursday that I find more interesting than the index level.

Seoul trades 9:00am to 3:30pm KST, which in August is 8:00pm to 2:30am ET. Wednesday's US session had already closed by then. And SKHY, the Nasdaq ADR SK Hynix floated on July 10, rose 9.01% to $154.41 on Wednesday with a market capitalisation of about $774 billion. Seoul opened four hours later and delivered 5.92%.

The US line led and the home market followed it, on a day with no SK Hynix news of its own. That is what a genuinely global listing looks like, and it is new: before July 10 there was no liquid dollar-denominated way to express a view on HBM outside Korean market hours, so price discovery happened overnight in Seoul and Americans read about it in the morning.

For a US reader the practical consequence is that the Korean close is no longer the first quote of the day. SKHY at $154.41 is above its $149 IPO price and below the $168.01 it closed on day one, so the biggest foreign listing in US history has spent a month going sideways through a crash and a bull market. The Temasek stake disclosed on Wednesday is one institution's answer to the same question.

What Would Break This

Three things, in the order I would watch them.

Memory contract pricing for the fourth quarter. The whole re-rating assumes DRAM and HBM pricing holds, and the negotiations that set it are happening now. A flat renewal would do more damage than any index level.

Foreign flows. Overseas investors have been net sellers of Korean equities across 2026, and Seoul Economic Daily reports some money coming back during this rally, with one figure of about $2 billion bought. I could not corroborate that number against a second source, so I would treat the direction as reported and the size as unconfirmed.

And leverage. July's crash was made worse by margin unwinding and leveraged ETF liquidations, which is why the authorities tightened leveraged-ETF rules afterwards. Margin debt coming down is the reason this rally has been steadier than the one that preceded the crash. If it starts climbing again, so does the tail risk. The July circuit-breaker sessions are recent enough to be worth remembering.

How a US Investor Can Actually Hold This

The Kospi itself is not directly buyable from a US brokerage account, which is a constraint worth naming before anyone goes looking for a ticker. The accessible expressions are narrower than the headline suggests:

• SKHY gives dollar exposure to the single stock driving most of the index move, with US market hours and listed options. It is one company, not the market.
• Broad Korea ETFs track the index, and their two largest holdings are the same two chipmakers. So the "diversified" version is substantially the concentrated version.
• Samsung Electronics has no US primary listing. The over-the-counter lines that exist are thin and are not the same instrument as the Seoul shares quoted above.

No options play is logged here. I could not source a live SKHY chain at the time of writing, and I am not going to quote a structure I cannot price.

The One-Line Read

Korea cleared the 20% line and is in a bull market, still 27.4% below the June record. The rally is real, the label flatters it, and the memory contracts negotiated this quarter matter more than either.
