أعمال · موجة بيع في السوق الكوريةتوقفات التداول في كوريا تعلّق البيع، لكنها تُبقي الخسائر الحادة قائمةكُتب 15 أكتوبر 2026 في 5:56 ص UTCشاهدالنص المفرّغ0:07South Korea's two main stock markets stopped trading after both indexes plunged 8%.0:13Each interruption lasted 20 minutes, cutting off trading as major chip makers0:17suffered steep losses.0:18The test is whether those pauses stopped the slide or simply interrupted it.0:23The Chaos DAC triggered its first-level circuit breaker at about 12.23 Thursday0:27afternoon, after falling 8.01%.0:31The ChaosB followed about 15 minutes later.0:33Both halts also stopped trading in associated derivatives.0:37The Chaos B hit its trigger at 5,528.05, that put it0:42480.76 points below the previous close, a fall of 8%.0:47But the exchange had already intervened twice that morning, using narrower0:50restrictions.0:51At about 9.08, the exchange suspended Chaos B program sell orders for five minutes.0:56The Chaos DAC followed at 9.12.0:58Those morning restrictions targeted automated selling by 12.23 and 12.38.1:03The interventions covered the entire affected stock markets.1:05The Chaos B's morning restriction, called a sell-sidecar, followed a 5.27% fall in1:11the relevant futures contract.1:12Futures are contracts tied to an index's expected value.1:16The sidecar rule watches a different instrument from the later circuit breaker.1:19The sidecar requires a futures decline of at least 5% for one minute.1:23The circuit breaker requires the Chaos B itself to stay at least 8% below its1:28previous close for one minute.1:29Its 20-minute halt reaches all shares in that market.1:32The futures test uses the Chaos B 200 contract with the preceding day's highest1:37trading volume.1:38Those detailed rules describe the Chaos B mechanism.1:40The historical comparison also belongs to the morning sidecars.1:44Both markets activated them together for the first time since July 29th, 51 trading1:48days earlier.1:49The Chaos B had already opened 5.59% lower.1:53It began at 5,673.01, down 335.801:58points.1:59Selling was severe from the opening bell.2:01well before the midday shutdowns.2:03At 10.30, the Chaos B was reportedly at 5,539.51.2:08By 1120, it had recovered to 5,604.6, down 6.73%.2:14Then it fell again to the circuit breaker threshold.2:16The 10.30 snapshot came with a quoted decline of 7.77%.2:22That percentage doesn't match the index level.2:24Against the previous close, the level implies about 7.81%.2:28The later plunge overtook that morning low.2:31The Chaos DAC halt was lifted at about 12.43.2:34The recorded seconds differ slightly across the halt notices and activation times.2:38Its reopening also had several stages, so lifting the interruption didn't2:42immediately restore normal continuous trading.2:45The Chaos DAC reopening notice allowed 10 minutes to collect orders, followed by an2:50auction setting a single price.2:51Continuous trading came afterward.2:53Block trades could execute from the start of order collection.2:56The exact actual Chaos B reopening time hasn't been specified.3:00Foreign investors had reportedly sold a net $1.92 trillion won by 10.30, about $1.43:05billion.3:06That extended their net selling into an eighth consecutive session.3:10The figure measures money moving out through net share sales during the morning.3:14At that same snapshot, Samsung Electronics traded at 211,001, down3:199.05%.3:21SK Hynex stood at 1,267,001, down 10.71%.3:26Both were still trading through an unfinished session.3:29Shareholders who kept their holdings faced sharply lower quoted values.3:32People needing to buy or sell also faced interrupted market access.3:36The foreign selling total has a different meaning from the amount of stock market3:39value erased and its morning cutoff matters when comparing it with earlier sessions.3:44The Chaos B closed about 5.5% lower on October 13th.3:48On October 14th, it lost another 0.44%, finishing at3:536,8.81.3:55The Chaos DAC fell 1.57% that day.3:59Foreign investors sold a net 1.18 trillion won during the whole October 14th4:04session.4:05Samsung finished flat, while SK Hynix fell.4:08Thursday's larger morning outflow and Wednesday's completed daily total cover4:12different periods.4:13FirmisGrid's collapsed initial public offering gave the AI financing worries a4:17concrete example.4:18The NVIDIA-backed data center operator had sought a stock market listing.4:22Its failure accompanied growing doubts about the cost of building AI infrastructure4:26and whether the spending will produce lasting profits.4:29Higher financing costs and stretched valuations added to those worries.4:33Investors were becoming more selective about AI infrastructure deals, but the failed4:37listing doesn't tell us how much of this Korean sell-off came from financing fears4:41or whether particular AI projects will ultimately earn profits.4:44CXMT, a Chinese memory chip maker, also claimed progress on a new DRAM4:49architecture intended to increase memory density.4:52DRAM is a common form of computer memory.4:55The competitive concern is that future Chinese advances could pressure established4:59producers' market share and price CXMT's technology claim concerns denser memory.5:04Commercial availability depends on production readiness and customer acceptance, and5:09a shipment timetable hasn't been given here.5:11A possible future memory glut remained a competitive risk rather than a measured5:16increase in chips already reaching customers.5:18The international backdrop added pressure too.5:21The cited figures put September U.S.5:23inflation at 3.7% year over year, above forecasts.5:27They also put the NASDAQ's October 14th loss at 1.88% and the S ⁇ P 500s at5:331.11%.5:34AI spending, Chinese competition, and interest rate worries all accompanied the5:38selling.5:39Their separate contributions haven't been measured.5:41Two dramatic online claims also remain unconfirmed, that $203 billion was wiped out5:47and that the Chaos B stood 40% below its June peak.5:50Korean market value had fallen below 5,000 trillion one on October 13th.5:55That earlier valuation level can't supply a dollar loss calculation for Thursday.5:59Such a calculation needs matching market values, comparison times, and an exchange6:04rate.6:04By 117, the Chaos B stood at 5,515.76, down6:108.13%.6:11The pauses had interrupted trading without reversing the steep decline.6:14That was an afternoon reading.6:16The final closing losses for both indexes weren't yet known.اقرأ المقالالتسلسل الزمني للقصةHeyDexالمقطع القصير ↗من نقل ماذانقاط نقلتها أكثر من وسيلة إعلاميةU.S. year-over-year inflation rateوسيلتا إعلامSK Hynix share declineوسيلتا
