Samsung and SK Hynix Give Back a Third of Friday's Record Surge
South Korea's Kospi closed down 5.13% at 6,257.41 on Monday, giving back roughly a third of Friday's record 17.91% surge as investors booked profits in Samsung Electronics and SK Hynix, both of which had rallied more than 20% the session before. Samsung fell 8.76% to 239,500 won and SK Hynix dropped 8.79% to 1,567,000 won, per TradingKey, as foreign investors sold a net 1.11 trillion won and institutions a net 247.1 billion won in Seoul trading, while individual investors alone bought a net 1.32 trillion won, per the Seoul Economic Daily. The reversal prompted swift target-price cuts: Shinhan Investment & Securities lowered its Samsung target to 450,000 won from 590,000 won and its SK Hynix target to 2.7 million won from 4.2 million won, while Samsung Securities cut Samsung to 400,000 won from 500,000 won and SK Hynix to 3 million won from 3.5 million won, per the Seoul Economic Daily.
"As the KOSPI surged more than 17% in a single day last Friday, marking its highest daily gain on record, there is room for temporary profit-taking and short-term pace adjustment early in the week. However, going forward, the domestic stock market is expected to show a recovery that raises its lows." — Han Ji-young, Analyst, Kiwoom Securities, via the Seoul Economic DailyHan's framing cast Monday's drop as a "pace adjustment" rather than a reversal of the memory-shortage thesis — a distinction Samsung Securities analyst Lee Jong-wook echoed, attributing the pullback to "an excessive concentration of investment ahead of a memory boom" rather than fresh doubts about demand, per the Seoul Economic Daily. That reading found an unlikely ally in Morgan Stanley, which upgraded Korean equities to Overweight and set a 9,000 Kospi target — implying 36% upside from Friday's close — arguing the month's leveraged-ETF and margin unwind was "mainly technical," according to strategists led by Daniel Blake, per Invezz. The two camps agree on direction but disagree on timing: Shinhan and Samsung Securities are cutting price targets even as Morgan Stanley calls the entry point attractive, leaving investors to judge whether Monday's 8%-plus declines are the last of the unwind or the start of a deeper repricing.

Chip Stocks Retreat as Korea's Record Rally Cools

Companies & Financials
NXP's Downgrade and Onsemi's Earnings Test the Analog Cohort
- NXP Semiconductors was downgraded to Neutral from Buy at UBS on Monday, which cut its price target to $270 from $305, per 24/7 Wall St. Why it matters: the reversal from one of the auto-chip sector's more bullish desks signals fading confidence in a near-term rebound for the analog and automotive cohort, a distinct read from the memory-driven volatility dominating the rest of the sector.
- ON Semiconductor reports second-quarter results after Monday's close, with the Zacks consensus calling for $1.59 billion in revenue and $0.72 in adjusted earnings per share, up roughly 8% and 36% year over year, per Yahoo Finance. Why it matters: as one of the few major chipmakers reporting during the Korea-driven memory selloff, the print is a direct test of whether automotive and industrial demand is stabilizing independent of the AI-memory cycle.

China's CXMT Deepens Its Beijing Footprint as Micron Wobbles
- China's CXMT is in early talks to build a second 12-inch DRAM plant in Beijing's Yizhuang district — where it already runs a roughly 100,000-wafer-a-month fab — alongside new plants under construction in Shanghai and Hefei expected to more than double its total capacity to over 600,000 wafers a month, Reuters reported Monday, per Yahoo Finance. Why it matters: Micron shares extended their decline in Monday premarket trading on the report, as investors weigh how quickly a state-backed Chinese rival could erode the pricing power behind this year's memory-industry profit surge.
- The Roundhill Memory ETF's three largest holdings — Micron at 29.16%, Samsung at 23.43% and SK Hynix at 20.27% — together account for more than 72% of the fund, with Western Digital and Seagate among the other storage names investors are watching this week, per Invezz. Why it matters: that concentration means Monday's Korea-driven reversal in Samsung and SK Hynix flows directly into a fund retail investors have used as a one-ticket bet on the memory cycle, amplifying the sector's volatility beyond the individual stocks.
Supply Chain
TSMC's Arizona Bet and ASML's Bernstein Nod Point Beyond Memory
- Taiwan Semiconductor's decision to raise its Arizona investment by $100 billion, bringing total committed U.S. spending to $265 billion, continues to draw bullish commentary from Wall Street, with a Motley Fool analysis published Sunday calling the expansion a hedge against geopolitical risk to its Taiwan-based production, per The Motley Fool. Why it matters: diversifying manufacturing capacity outside Taiwan reduces the single-country concentration risk that has weighed on TSMC's valuation, even as the company continues to book record revenue from its home fabs.
- ASML shares edged higher in Monday premarket trading after Bernstein named the lithography maker one of its top picks for the third quarter, per TipRanks. Why it matters: a bullish equipment-sector call from a major sell-side desk offers a counterpoint to the China-competition and demand-cycle concerns that have weighed on ASML and the broader wafer-fab-equipment group this summer.
Policy Desk
Regulators Target Leverage as Geopolitics Cuts the Other Way
- South Korea's Financial Services Commission and Financial Supervisory Service are pushing an amendment that would grant regulators emergency authority to cut the leverage ratio on single-stock leveraged ETFs from 2x to as low as 1x during periods of extreme volatility, per TradingKey. Why it matters: leveraged ETFs tracking Samsung and SK Hynix have amplified this month's swings in both directions, and a lower leverage cap would directly reduce the trading-volume and volatility profile of Korea's two largest listed companies.
- President Trump said Sunday that talks with Iran will resume this week after he called off planned strikes, sending West Texas Intermediate crude down 6.21% to $79.41 a barrel and Brent down 5.11% to $83.24 on Monday, per TheStreet. Why it matters: falling oil prices and reduced geopolitical risk helped lift broader U.S. equity futures Monday, a partial offset to chip-stock weakness driven specifically by Korea's profit-taking rather than any change in AI-demand fundamentals.
Analyst Corner
A China Deep Dive and a Contrarian Korea Call Frame the Debate
- SemiAnalysis (background reading, published Jun 23): "China's CXMT Is Set to Challenge DRAM Incumbents" details how the Chinese DRAM maker's expanding capacity and cash generation could pressure Samsung, SK Hynix and Micron over time — the structural backdrop behind Monday's report that CXMT is financing a second Beijing plant.
- Morgan Stanley, via Invezz: strategists led by Daniel Blake upgraded Korean equities to Overweight and set a 9,000 Kospi target, arguing July's rout in SanDisk (-47%), Micron (-29%) and the Roundhill Memory ETF (-32%) was "mainly technical" — a leverage and margin unwind rather than a demand collapse, per Invezz.
Calendar / Week Ahead
AMD and SanDisk Headline a Pivotal Earnings Week
- Tuesday, Aug 4 — AMD reports second-quarter results after the close. Wall Street expects revenue of roughly $11.3 billion and EPS of $1.62, with options pricing implying a 12.28% move on the print, per TipRanks.
- Wednesday, Aug 5 — SanDisk reports fiscal fourth-quarter and full-year 2026 results, ahead of an August 13 investor day, per Business Wire.
