DRAM spot prices historically turn one to two quarters before Samsung Electronics and SK Hynix earnings inflect — and those two stocks drive the KOSPI. Here is where to find the DXI index, DRAMeXchange spot quotes, and hyperscaler capex guidance, and how to read a cycle turn step by step.
The KOSPI surged 17.91% to 6,595.45 — its biggest one-day gain on record — as strong US tech earnings eased AI profitability fears and foreign investors piled back in after a brutal two-week selloff capped by back-to-back circuit breakers.
Korea’s KOSPI fell 5.98% and the KOSDAQ 6.12%, with market-wide circuit breakers halting both boards for a second straight day. SK hynix’s guidance letdown and forced selling from single-stock leveraged products drove the slide.
The KOSPI fell 10.84% to 6,023.66 and briefly broke below 6,000 as China semiconductor fears hammered Samsung Electronics and SK hynix. Both exchanges halted trading with sidecars and circuit breakers while foreign investors dumped roughly $3.4 billion of Korean stocks.
One company accounts for roughly a fifth of Korea’s benchmark index. Here is how KOSPI’s cap-weighted methodology turns Samsung Electronics and the memory-chip cycle into the index itself – and what that means for anyone tracking or buying Korean equities.
Korea’s KOSPI jumped 7.01% to 7,284.41 after a softer US CPI print eased Fed tightening fears, tripping buy sidecars on both exchanges. Foreign investors bought roughly $1.6 billion of KOSPI shares, but the index remains about 14% below its June 30 level.
Korea’s KOSPI plunged 8.95% to 6,806.93 on Monday, triggering the year’s seventh circuit breaker, as SK hynix fell 15.4% and Samsung Electronics 10.7% on Middle East tensions and a leveraged-ETF flow shock.
The KOSPI rose 2.52% and the KOSDAQ jumped 5.47% as a US chip rally and seven-times-oversubscribed demand for SK hynix’s Nasdaq ADR listing fired up sentiment, triggering buy-side sidecars. Institutions bought the dip while retail and foreign investors sold.
The KOSPI closed up 0.62% at 7,291.91 after an extreme intraday swing of roughly 480 points. SK hynix surged 5.3% on US ADR listing hopes while institutions absorbed about $880 million of retail selling.
SK hynix lists on the Nasdaq on July 10 as SKHY in the largest-ever US stock sale by a foreign company. The view from Seoul: a stock that tripled in six months, a W28 trillion foreign selling streak that just flipped, and what the ADR changes for the KOSPI-listed shares.
