South Korea’s benchmark KOSPI index fell 5.36% on Monday, dropping 353.68 points to trade at 6,241.77, as investors locked in profits following the index’s historic single-day surge just two trading sessions earlier.

The index opened sharply lower Monday, initially falling 3.6% before extending losses to as much as 4.25%, dropping 280.05 points to 6,315.4 shortly after 9:15 a.m. local time, according to the Korea JoongAng Daily. The pullback continued through the morning session, pushing the decline past 5% by early afternoon.

Monday’s retreat came directly on the heels of Friday’s record-breaking rally, when the KOSPI surged 17.91% in a single session, the largest one-day percentage gain in the index’s history, following blockbuster earnings from Microsoft, Amazon and Meta Platforms that had eased broader concerns about the sustainability of artificial intelligence infrastructure spending. That Friday rally itself followed a brutal three-session stretch in which the KOSPI had plummeted more than 17%, at one point falling roughly 40% from its June peak.

Notably, Monday’s decline came even as Wall Street posted a positive session heading into the new trading week, with robust earnings from Amazon continuing to fuel investor optimism toward the broader artificial intelligence sector. That divergence between a positive US session and a sharply negative Korean one underscored how much of Friday’s historic rally had been driven by profit-taking and short-covering dynamics specific to the Korean market, rather than a durable, fundamentals-driven shift in sentiment toward Korean chip stocks.

The current bout of extreme volatility fits a broader pattern that has defined South Korean equity markets throughout 2026. The Korea Exchange has repeatedly triggered trading halts, including both sell-side sidecars, which temporarily suspend program sell orders, and circuit breakers, which pause all trading entirely, on numerous occasions this year. By late June, the exchange had already logged close to 30 sidecar activations and five circuit breakers for the year, a pace that had already surpassed the KOSPI’s prior annual record of 26 sidecar halts, set during the 2008 global financial crisis.

Much of the extreme volatility has been driven by the outsized weighting of Samsung Electronics and SK Hynix within the index. The two chipmakers together account for roughly half of the KOSPI’s total market capitalization, meaning sharp swings in either stock, in either direction, tend to translate directly into equally dramatic swings for the headline index. Both companies have repeatedly whipsawed between steep declines and sharp rebounds in recent weeks, tracking a broader global reassessment of artificial intelligence-related chip demand and valuations that has played out across markets in the United States and Asia alike.

Frank Benzimra, head of Asia equity strategy at Societe Generale in Hong Kong, pointed to the concentrated nature of the recent selling pressure when South Korean markets first began plunging in late July. “If you look at what is falling in the market, it has been the stocks in which you have the most leverage,” Benzimra said, according to Al Jazeera, highlighting how heavily leveraged positions tied to chip and technology stocks have amplified the scale of the market’s swings in both directions.

The scale of the recent turbulence has been extraordinary even by the standards of a market that had posted extraordinary gains over the prior 18 months. South Korean equities surged roughly 75% during 2025, driven substantially by the global boom in artificial intelligence and semiconductor demand, before extending those gains with another roughly 50% climb earlier in 2026 as global capital continued flowing into the country’s technology sector. That backdrop of extraordinary prior gains has left the index unusually vulnerable to sharp reversals whenever sentiment toward AI-related chip demand shifts, given how significantly valuations across the sector had climbed during the preceding rally.

South Korean regulators have moved to address the underlying volatility directly in recent days. New cash-deposit requirements for investors using leveraged exchange-traded funds took effect July 31, a change specifically designed to reduce the kind of mechanically amplified trading swings that have repeatedly gripped both the KOSPI and the smaller KOSDAQ index throughout the year.

With the KOSPI now retreating sharply from Friday’s historic gain, market analysts continue to caution against reading too much into any single day’s move given the scale of the index’s recent whipsaw trading. Investors are likely to remain focused in the coming sessions on further earnings reports from major global technology companies, along with any additional developments involving Samsung and SK Hynix specifically, as key factors determining whether South Korean equity markets can find a more stable footing following one of the most volatile stretches in the exchange’s history.

Meghan Markle’s decision to join Prince Harry and their two children for last month’s private reunion with King Charles III at Highgrove House was aimed at presenting a unified family front to Archie and Lilibet, according to veteran royal commentator Jennie Bond.

The Duchess of Sussex traveled to Britain alongside Harry, Archie and Lilibet for the meeting at Highgrove, the king’s private Gloucestershire estate, marking the first time Charles had seen his two grandchildren in person in more than four years and the first time Meghan had returned to the UK since 2022. Buckingham Palace confirmed the gathering shortly after it occurred but released no further details or photographs.

Bond, a former BBC royal correspondent, told the Mirror that Meghan’s presence at the reunion served an important purpose for how the children experienced the visit. “It’s a good thing that [Meghan] was part of the family reunion at Highgrove a few weeks ago,” Bond said. She argued that excluding Meghan from the gathering would have complicated the experience for Archie and Lilibet. “The children deserve to see some family harmony: it would have been damaging to have to explain that their mother wasn’t invited,” Bond said.

Bond also offered her own read on where Meghan’s broader focus currently lies, suggesting the duchess’s attention remains centered on the family’s life away from royal duties. “I think her eyes are firmly set on their lives in California, their children and her business ventures,” Bond said.

The Highgrove meeting followed a gradual, incremental thaw in relations between Harry and his father that had been building for months beforehand. In September 2025, Harry and Charles held a private tea at Clarence House, their first in-person meeting in 19 months, which Buckingham Palace also confirmed at the time. That earlier meeting came after Harry told the BBC in May 2025 that his father would not speak to him “because of this security stuff,” while expressing hope for reconciliation. “I would love reconciliation with my family,” Harry said in that interview. “There’s no point in continuing to fight anymore. Life is precious.”

Harry and Meghan stepped back from official royal duties in 2020 and relocated to California, a decision that ended Harry’s automatic entitlement to UK police protection and has remained a persistent point of tension between the couple and the royal family. Harry has pursued legal challenges over his security arrangements in the years since, losing his most recent appeal earlier this year. That unresolved dispute shaped much of the planning around the Highgrove visit, with reports beforehand questioning whether it would be safe for Meghan and the children to travel given the lack of state-funded protection.

The relationship between Harry and the rest of the family has remained strained well beyond the security dispute, particularly following the 2023 publication of Harry’s memoir, “Spare,” in which he made pointed and personal claims about tensions with his brother, Prince William, and other family members. Notably absent from the Highgrove reunion were William and Catherine, Princess of Wales, who instead appeared together at a separate public event in Windsor the same day. Royal editor Roya Nikkhah of The Sunday Times has reported that William and Harry have not seen or spoken to each other since Queen Elizabeth II’s funeral in 2022, writing that William is unlikely to welcome his father’s outreach to the Sussexes.

The Highgrove visit was not the only significant milestone in the family’s recent reconciliation efforts. Prior to the meeting, reports had indicated King Charles was open to allowing Harry and Meghan to stay at Highgrove during future UK visits, a gesture some royal watchers interpreted as an effort to offer the couple greater privacy compared with staying at more heavily scrutinized royal residences. Meghan and the children had not previously visited the UK together with Harry since the funeral of Queen Elizabeth II in September 2022.

Bond’s comments reflect one interpretation among several that have circulated among royal commentators regarding the significance of Meghan’s inclusion in the Highgrove gathering, with observers broadly divided over whether the visit signals a meaningful and lasting shift in relations between the Sussexes and the wider royal family or represents a more limited, one-off gesture tied specifically to allowing Charles time with his grandchildren.

As of early August, neither Buckingham Palace nor representatives for the Sussexes have provided additional public comment on the Highgrove meeting beyond confirming that it took place, and no further details have emerged regarding whether additional visits or meetings between the two branches of the family are being planned in the near future.
