The Korea Composite Stock Price Index or KOSPI was launched in 1983 with the base value of 100 as of January 4, 1980. KOSPI is the major stock market index of South Korea. The index represents all common stocks traded on the Korea Exchange. The index calculation is based on market capitalization method. KOSPI replaced Dow-style KCSPI (Korea Composite Stock Price Index) in 1983.
KOSPI moved below 1,000 mark for several years. The index breached 1,000 for the first time in April 1989. KOSPI recorded its largest one-day percentage gain of 8.50% on June 17, 1998 & largest one-day percentage drop of 12.02% on September 12, 2001. The index’s Korean name was officially changed to Koseupi jisu in November 2005. KOSPI reached another milestone of breaking 2000 level for the first time on July 24, 2007.

Index cuts losses near session close as retail investors buy the dip
SEOUL, July 7 (Reuters) – South Korean shares tumbled on Tuesday, with the benchmark index triggering a temporary trading halt, as chipmakers slumped on doubts over whether record earnings tied to AI could hold up. Six of the exchange’s 12 circuit breakers, or 20-minute trading halts, were activated this year, reflecting heightened volatility in semiconductor stocks.

Shares fall as much as 10% following steep rise this year
While Samsung has benefited massively from the AI data centre boom that has propelled memory chip prices to record highs, the outlook for chipmakers has been clouded by worries U.S. tech giants may slow their infrastructure plans and curb chip demand. Samsung estimated April-June operating profit at 89.4 trillion won ($58.44 billion), beating an LSEG SmartEstimate of 87.3 trillion won, according to a regulatory filing. It reported a profit of 4.7 trillion won a year earlier. Revenue would likely rise 129% to 171 trillion won from a year earlier, it said. Analysts attributed the declines to some lofty market expectations and worries that spending on AI data centres may slow down.
“Samsung’s strong earnings were widely expected and had largely been priced in after its shares rallied ahead of the results,” said Albert Yong, a managing partner at Petra Capital Management, which owns Samsung stock.
“Investors remain concerned about the sustainability of the AI boom and the risk of slower AI infrastructure spending by major U.S. technology firms.”
SLOWER CHIP PRICE GROWTH AHEAD?
Memory chip prices continued to climb during the quarter as AI spending broadened beyond high-bandwidth memory (HBM) into conventional DRAM and NAND products. Citi Research last week said average selling prices for DRAM and NAND rose 44% and 53% quarter-on-quarter, respectively, in the second quarter.
However, Morningstar analyst Jing Jie Yu said Samsung’s revenue estimate was not as strong as expected.

Samsung union suspends planned strike after reaching tentative pay deal Explainer: What are Samsung union workers demanding and how might a strike play out?
- Union suspends plan to start 18-day strike on Thursday
- Union leader says reached deal on profit distribution
- Strike had threatened to disrupt chip production
Samsung Electronics’ labour union members chant slogans during a protest against company’s compensation levels ahead of a planned lengthy strike in front of Samsung Electronics semiconductor plant in Pyeongtaek, South Korea, April 23, 2026. Samsung, labor union to resume talks on Wednesday as they edge to avert strike and its South Korean labor union will resume talks on Wednesday, the National Labor Relations Commission said, as they edge toward an agreement to avert a damaging and lengthy strike.
“The management and union have not reached common ground on one issue,” Park Su-keun, chair of the commission, told reporters when asked why more than 15 hours of talks on Tuesday had failed to produce an agreement.
- Two sides spoke for nearly 15 hours
- Talks stuck on one key issue, despite some concessions
- Union plans 18-day strike from Thursday
He added that it was “the most important issue,” without elaborating. At Samsung, the global AI boom spurred a looming strike and deep divisions Samsung chip profit jumps almost 50-fold; supply shortage to worsen in 2027 on Thursday reported record quarterly profit driven by a 49-fold jump in chip income, saying it expects a severe supply shortage to deepen next year as clients spend on AI, driving up prices of its memory chips.

SEOUL, May 15 (Reuters) – A looming 18-day strike at South Korean chip giant Samsung that has triggered worries within the government, rattled foreign investors and threatened global supply chains rests on one crucial question: who should share in the spoils of the AI boom?
More than 45,000 workers are threatening to stage the largest strike in the conglomerate’s history from May 21, reducing production of memory chips that are crucial components in AI data centres, smartphones and laptops, as Samsung and its union struggle to find a compromise over bonus payouts. A boom in the construction of AI data centres has spurred Samsung and chipmaking peers to allocate production capacity to advanced chips that Nvidia uses in its so-called AI accelerators. Even so, chipmakers are struggling to meet demand while the move also squeezes the supply of conventional chips.
“Our supply falls far short of customer demand,” Kim Jaejune, a Samsung memory chip business executive, told analysts on its post-earnings call. “Based solely on the demand currently received for 2027, the supply-to-demand gap for 2027 is set to widen even further than in 2026.” Continued development in AI technology will translate into sustained demand growth yet supply will remain constrained for the time being considering the lead time required for new factory construction, Kim said. Revealing the extent of the AI boom, Samsung said January-March operating profit in its cash cow chip division reached a record 53.7 trillion won ($36.15 billion) from just 1.1 trillion won in the same period a year earlier. That made up 94% of the quarter’s 57.2 trillion won record total. That figure matched Samsung’s estimate announced earlier this month and compared to 6.69 trillion won a year prior.
Overall revenue rose 69% on year to 133.9 trillion won.
Samsung said conflict in the Middle East has not disrupted chipmaking as the firm has secured inventory and diversified sources of gases used in manufacturing. However, it flagged the risk of higher transportation costs caused by rising oil prices, and said it will ensure stable power supplies in cooperation with the South Korean government.
SAMSUNG READIES FOR LOOMING STRIKE
Samsung has been trying to narrow the gap with compatriot SK Hynix in supplying high bandwidth memory (HBM) chips to Nvidia, having fallen behind to the detriment of both profit and share price. SK Hynix sets record as quarterly profit jumps five-fold, says AI chip demand exceeds capacity record for quarterly profit with a five-fold jump in earnings and forecast AI chip demand would exceed manufacturing capacity, allaying concern about slowing AI spending by big tech firms.
The outlook by the Nvidia
- AI-driven demand boosts DRAM and NAND prices
- Chip supply tight even as capacity expands
- SK Hynix plans significant investment in plants, EUV tools
- Chipmaker to review shareholder return measures
- Shares surge nearly 90% this year, market value surpasses ASML’s
SEOUL, April 23 (Reuters) – South Korea’s SK Hynix on Thursday set a record for quarterly profit with a five-fold jump in earnings and forecast AI chip demand would exceed manufacturing capacity, allaying concern about slowing AI spending by big tech firms. The outlook by the Nvidia supplier signals strong momentum remaining intact for high bandwidth memory chips used in AI chipsets, keeping supplies constrained and prices high.
“Client requests for (HBM) chip supplies over the next three years already far exceeds our production capacity,” Ki Tae Kim, head of HBM sales and marketing, said on an earnings call. The world’s second-largest memory chipmaker after Samsung Electronics also said it sees limited impact from war in the Middle East, having secured inventory and diversified suppliers of key chemicals, and securing energy through long-term contracts, minimising the impact of price volatility.
CHIP PRICE RALLY SEEN EASING
Contract prices for certain DRAM chips jumped nearly 83% in the first quarter from the previous quarter, while prices for some NAND products soared around 160%, showed data from market tracker TrendForce. It expects prices to rise in the current quarter, signalling another quarter of robust earnings growth, as tech firms race to secure chips for AI infrastructure.
The pace of price increases may begin to ease after the second quarter, but constrained supply will continue until new production capacity comes online, which can take more than a year after construction begins, analysts said. SK Hynix said it expects a favourable pricing environment to continue “for the time being” as AI-driven demand offsets softer demand from PC and smartphone makers. SK Group chairman says wafer shortage to last until 2030, trying to stabilise memory prices SK Group chairman Chey Tae-won expected chip wafer shortage to last until 2030
Chey points to new strategy for stabilising DRAM prices
SK Hynix looks into U.S. ADR listing to broaden its global presence
SAN JOSE, California, March 16 (Reuters) – South Korea’s SK Group Chairman Chey Tae-won said on Monday the global chip wafer shortage is likely to persist until 2030, as demand driven by artificial intelligence continues to outpace supply. Speaking to reporters on the sidelines of Nvidia’s GTC Conference in San Jose, California, Chey said that SK Hynix is reviewing a potential U.S. ADR listing to broaden its global investor base, while its CEO may unveil plans to stabilise DRAM chip prices and the group explores alternative energy sources. SK Hynix, the main high-bandwidth memory (HBM) supplier to Nvidia, ranks No.1 in the HBM market with a 57% share and holds a 32% share of the global DRAM market, making it the second-largest player, according to Counterpoint.
“AI actually wants to have a lot of HBM, and once you make the HBM…we have to use a lot of wafers,” said Chey, explaining the shortage of wafers.
“So we need some time to build up more wafers, at least four to five years. The current shortage could continue until 2030, so we expect more than a 20% shortage of the wafers,” Chey said. He said that SK Hynix would try to come up with a strategy to stabilise DRAM prices.
“So I cannot just announce right here, but I guess that our CEO is going to announce a new plan for how to stabilise the price of the DRAM,” Chey said.
When asked about expanding chip manufacturing capacity in the United States, where many of SK Hynix’s customers are based, Chey said establishing overseas plants required adequate power, water, construction conditions and engineering talent. Accordingly, he said this could not be done easily on demand, adding that the company was currently focusing on production in Korea. On a potential U.S. ADR listing, Chey said the move could help expand SK Hynix’s shareholder base beyond Korea, increasing exposure to American and international investors and strengthening its global presence.
Chey also said tensions in the Middle East had created a lot of difficulties due to higher energy prices, pushing the group to seek other available energy sources.
Shares of SK Hynix were trading up 2.7% on Tuesday morning in Seoul, versus the benchmark KOSPI’s 2.4% rise.

No signs of a slowdown in memory chip demand, executive says
SEOUL/SAN FRANCISCO, Jan 15 (Reuters) – SK Hynix plans to accelerate the opening of a new factory by three months and will also begin operating another new plant in February, a senior executive said, as surging memory demand pressures global supply.
The South Korean chipmaker’s decision comes as AI frenzy is driving a memory chip supply crisis Magnifier screens show chips at a booth in a mall of Huaqiangbei electronics market in Shenzhen, Guangdong province, China October 30, 2025. Dec 3 (Reuters) – An acute global shortage of memory chips is forcing artificial intelligence and consumer-electronics companies to fight for dwindling supplies, as prices soar for the devices to store data.
Japanese electronics stores have begun limiting how many hard-disk drives shoppers can buy. Chinese smartphone makers are warning of price increases. Tech giants including Microsoft and ByteDance are scrambling to secure supplies from memory-chip makers such as Micron, according to three people familiar with the discussions. The squeeze spans almost every type of memory, from flash chips used in USB drives and smartphones to advanced high-bandwidth memory (HBM) that feeds AI chips in data centers. Prices in some segments have more than doubled since February, according to market-research firm TrendForce, drawing in traders betting that the rally has further to run.
The fallout could reach beyond tech. Many economists and executives warn the protracted shortage risks slowing AI-based productivity gains and delaying hundreds of billions of dollars in digital infrastructure. It could also add inflationary pressure just as many economies are trying to tame price rises and navigate U.S. tariffs. “The memory shortage has now graduated from a component-level concern to a macroeconomic risk,” said Sanchit Vir Gogia, CEO of Greyhound Research, a technology advisory firm. The AI build-out “is colliding with a supply chain that cannot meet its physical requirements.”
This Reuters examination of the spiraling supply crisis is based on interviews with almost 40 people, including 17 executives at chipmakers and distributors. It shows industry efforts to meet voracious appetite for advanced chips — driven by Nvidia — created a dual bind: Chipmakers still can’t produce enough high-end semiconductors for the AI race, yet their tilt away from traditional memory products is choking supply to smartphones, PCs and consumer electronics. Some are now hurrying to course-correct. Details of the global scramble by tech firms and price increases described by electronics retailers and component suppliers in China and Japan are reported here for the first time.
Average inventory levels at suppliers of dynamic random-access memory (DRAM) — the main type used in computers and phones — fell to two to four weeks in October from three to eight weeks in July and 13 to 17 weeks in late 2024, according to TrendForce. The crunch is unfolding as investors question whether the billions of dollars poured into AI infrastructure have inflated a bubble. Some analysts predict a shakeout, with only the biggest and financially strongest companies able to stomach the price increases.
One memory-chip executive told Reuters the shortage would delay future data-center projects. New capacity takes at least two years to build but memory-chip makers are wary of overbuilding for fear it could end up idle should the demand surge pass, the person said. Samsung and SK Hynix have announced investments in new capacity but haven’t detailed the production split between HBM and conventional memory. SK Hynix has told analysts that the memory shortfall would last through late 2027, Citi said in November.
“These days, we’re receiving requests for memory supplies from so many companies that we’re worried about how we’ll be able to handle all of them. If we fail to supply them, they could face a situation where they can’t do business at all,” Chey Tae-won, chairman of SK Hynix parent SK Group, said at an industry forum in Seoul last month.
Samsung told Reuters it is monitoring the market but wouldn’t comment on pricing or customer relationships. SK Hynix said it is boosting production capacity to meet increased memory demand.
Microsoft declined to comment and ByteDance didn’t address questions about the chip strain. Micron and Google didn’t respond to comment requests.
‘BEGGING FOR SUPPLY’
After ChatGPT’s release in November 2022 ignited the generative AI boom, a global rush to build AI data centers led memory makers to allocate more production to HBM, used in Nvidia’s powerful AI processors.
Competition from Chinese rivals making lower-end DRAM, such as ChangXin Memory Technologies, also pushed Samsung and SK Hynix to accelerate their shift to higher-margin products. The South Korean firms account for two-thirds of the DRAM market.
Samsung told customers in May 2024 that it planned to end production of one type of DDR4 chips — an older variety used in PCs and servers — this year, according to a letter seen by Reuters. (The company has since changed course and will extend production, two sources said.) In June, Micron said it had informed customers it would stop shipping DDR4 and its counterpart LPDDR4 – a type used in smartphones – in six to nine months.
ChangXin followed suit in ending most DDR4 production, one source said. The firm declined to comment.
This shift, however, coincided with a replacement cycle for traditional data centers and PCs, as well as stronger-than-expected sales of smartphones, which rely on conventional chips.
In hindsight, “one could say the industry was caught off-guard,” said Dan Hutcheson, senior research fellow at TechInsights.
The chipmaker said investment this year will rise significantly from last year’s 30.2 trillion won ($20.37 billion), with a focus on building infrastructure at the Yongin Cluster, ramping up the M15X fab, and securing key equipment.
In March, SK Hynix said it would purchase 11.95 trillion won worth of EUV lithography tools from ASML.
by 2027.
The chipmaker also said it is reviewing shareholder return measures, including dividends, share buybacks and cancellations, and aims to finalise plans within the year.
SK Hynix reported a 37.6 trillion won operating profit for January-March, from 7.4 trillion won a year earlier.
That was in line with a 37.9 trillion won LSEG SmartEstimate, which is weighted toward analysts who are more consistently accurate.
Quarterly revenue rose 198% to 52.6 trillion won.
SK Hynix’s share price was up 2.1% in morning trade, compared with the benchmark KOSPI’s 1.2% rise.
The stock has jumped nearly 90% so far this year, with a market value climbing to about $590 billion, surpassing the $570 billion of ASML Europe’s most valuable company.
