Semiconductor stocks that had roughly doubled during the second quarter of 2026 have started unwinding those gains fast, with the Philadelphia Semiconductor Index losing 6.7% in a two-session slide that has wiped out billions in market value even as broader indices climb toward record territory, according to CNBC’s markets desk.

The Sell-Off’s Anatomy

The damage has concentrated in specific names rather than spreading evenly across the sector. Sandisk tumbled 10.6%, Applied Materials fell about 10%, and Micron Technology, Lam Research, Intel, and Marvell each lost between 5.5% and 10% as investors took profits following what Schwab’s market desk described as a great run for chip stocks through the second quarter, per Schwab’s update. Teradyne and KLA fared worse still, sliding 13.6% and 11.5% respectively, dragging the VanEck Semiconductor ETF down 4.5% in a single session, according to CNBC.

Even Nvidia, the bellwether that has anchored the AI trade since 2023, pulled back 1.4%, a modest decline by comparison but notable given the stock’s outsized influence on index-level performance. The moves have come despite Applied Materials carrying a Zacks Rank #1, or “Strong Buy,” rating, illustrating that the current rotation is driven by positioning and sentiment shifts rather than any change in fundamental analyst outlooks, per Zacks’ coverage.

Rotation, Not Retreat

What distinguishes this pullback from a broader risk-off event is where the money is flowing instead. Communication services and financial stocks were the session’s biggest gainers, with the sector-tracking SPDR funds for each rising 2.4% and 2.2% respectively even as the Information Technology Select Sector SPDR dropped 2.6%, Zacks reported. One market strategist characterized the move as “a rotation potentially out of a sector that’s been red hot for the last few months and into other areas,” while also noting a broader revaluation of the AI trade itself is underway, language captured in CNBC’s live coverage.

Netflix shares jumped 5% on Thursday afternoon, making the streaming company a standout outperformer within the Nasdaq-100 even as that index sold off roughly 2% overall, on pace for its best single day since late February and a 5.6% weekly gain heading into the holiday-shortened trading week, per CNBC.

The Meta Cloud Pivot Adds a New Wrinkle

Adding to the sector’s uncertainty, news broke that Meta plans to begin renting out portions of its computing infrastructure, positioning the social media company as a direct competitor to smaller cloud providers such as Nebius and CoreWeave. JPMorgan analyst Doug Anmuth pushed back on the strategy in a note to clients, arguing the company would be better served developing its own inference capabilities to strengthen its advertising business rather than diversifying into infrastructure rental, according to CNBC’s reporting on the note.

The episode illustrates a broader tension within the AI capital expenditure story: as detailed in the Bank for International Settlements’ recent warning about AI-related credit risk, hyperscalers are increasingly searching for revenue streams to justify capex that already outpaces free cash flow, and Meta’s cloud pivot can be read either as prudent diversification or as a signal that internal AI economics are not yet closing the gap analysts expected.

What This Means Going Into a Holiday-Shortened Week

US markets closed Friday, July 3, for Independence Day, meaning the semiconductor sector enters a long weekend carrying two days of sharp losses without the usual next-session opportunity to stabilize. The next scheduled catalyst is the ISM June Services PMI on July 6, followed by FOMC minutes on July 8, both of which will shape whether the current rotation out of chip stocks and into rate-sensitive sectors continues or reverses.

Small-cap stocks, meanwhile, just posted their best first half since 1991, according to Google Finance’s markets summary, a data point that reinforces the rotation narrative: capital appears to be broadening out from the concentrated AI mega-cap trade that dominated 2025 and early 2026 into a wider set of market segments, even as the underlying question of whether AI infrastructure spending can generate the returns markets have priced in remains unresolved.

South Korea’s won has not traded at these levels since Lehman Brothers collapsed and the world was sorting through the wreckage of its worst financial crisis in eighty years. That the currency has returned to those depths under entirely different circumstances — not a global credit event, but a sustained combination of dollar strength, political uncertainty, and structural capital outflows — makes the current episode more complex, and in some ways more concerning, than 2009.

The Numbers

On July 1, 2026, the won declined as much as 0.6 percent to 1,559.10 per dollar, following a prior session low of 1,562.20 — a level last seen in March 2009. Overseas investors sold a net 1.46 trillion won ($938 million) of stocks in the Kospi index on a single trading day, marking the eighth consecutive session of equity outflows from the Korean market.

“The dollar’s strength is such that a fresh low for the won would not be surprising,” said Moon Dawoon, an economist at Korea Investment & Securities. “If it does break through, it will be difficult to identify the next technical level, so from a qualitative perspective, the downside for the won should be kept open to around 1,600 per dollar.”

A breach of 1,600 would represent territory not visited since the 1997 Asian financial crisis — a threshold that carries both technical and psychological significance for regional currency markets.

Why the Won Is Falling

The 2026 won story is not a simple export slump. South Korea continues to run a current-account surplus — $18.70 billion in December 2025, $13.26 billion in January 2026. The fundamentals of the trade balance have not deteriorated dramatically. What has changed is the capital account.

Several forces are pulling simultaneously in the wrong direction. The US-Korea interest rate differential remains wide, making dollar-denominated assets relatively attractive to Korean investors. Structural outward investment — Korean residents and institutions consistently moving capital into foreign assets — keeps upward pressure on dollar demand. Trade friction and tariff uncertainty from the United States raise risk premia on Korean assets broadly. And geopolitical stress in the Middle East has driven a risk-off flight to dollar safety that penalises emerging market currencies disproportionately.

The IMF estimated Korea’s growth at 0.9 percent in 2025, with a projected rebound to 1.8 percent in 2026 — an improvement, but well below Korea’s historical growth trajectory. The Bank of Korea has held its base rate at 2.50 percent, balancing growth support against exchange-rate and financial stability concerns.

The Semiconductor Exposure

Korea’s currency vulnerability is amplified by its sector concentration. Samsung and SK Hynix together constitute a dominant share of the global memory chip market — and global memory chip markets are themselves being stress-tested by the AI infrastructure boom. The so-called “RAMageddon” dynamic, in which AI-fuelled demand for memory chips has sent prices soaring, has provided export revenue support. But it has also created concentration risk: a reversal in AI capex demand, which the BIS and Chinese hedge funds have been warning about, would hit Korea’s export base and currency simultaneously.

The Kospi index’s heavy weighting toward Samsung, Hyundai, and semiconductor-adjacent companies means that institutional investors who reduce technology sector exposure globally tend to sell Korean equities as a primary execution path. Eight consecutive days of outflows is the market expressing that thesis in real time.

Regulatory Response

Following an earlier episode in which the won slid to its lowest since 2009 in June 2026, South Korean authorities convened an emergency meeting between the Bank of Korea governor and financial regulators. The government announced measures including stepped-up oversight of offshore currency derivatives, boosted inspections for suspected market misconduct, and investigations into potentially illegal foreign-exchange transactions.

The won briefly rebounded following those announcements before resuming its decline in early July. The pattern is familiar in currency management: administrative measures can slow momentum but rarely reverse the underlying capital flow dynamics that are driving the move.

Regional Contagion Signals

The won’s decline on July 1 led a broader retreat in Asian currencies, reflecting the dollar’s role as the default safe haven in periods of global risk aversion. The Japanese yen simultaneously extended losses to multi-decade highs against the dollar — a different dynamic driven by the US-Japan rate differential, but contributing to a picture of simultaneous stress across the major Asian currency pairs.

Emerging market investors are monitoring whether won weakness begins translating into spillover dynamics: whether Korean retail investors rotate into crypto as a won hedge (measurable through the “kimchi premium” on Korean crypto exchanges), and whether institutional outflows from Korean equity and bond markets intensify as currency losses erode total returns for foreign holders.

A currency at 1,562 per dollar, trending toward 1,600, with eight straight days of equity outflows and a semiconductor sector exposed to an AI capex cycle that global institutions are increasingly questioning — is not a crisis yet. But it is accumulating the conditions for one.

Michael Burry, the investor who rose to fame for correctly predicting the 2008 housing market collapse, has revealed he considered betting against Elon Musk’s SpaceX — but ultimately decided against it. The admission, surfacing just as SpaceX moves toward a long-anticipated public listing, has quickly become one of the most talked-about lines in markets this week.

Why Burry’s Words Carry Weight

Few investors generate headlines the way Burry does. His reputation as a contrarian who isn’t afraid to bet against popular narratives means that even a passing comment about being “tempted” to short a company is enough to move conversation across trading desks and social media alike. The fact that he chose not to follow through only adds intrigue, leaving observers to speculate about what gave him pause.

The SpaceX Backdrop

The comments land at a notable moment for SpaceX, which has been the subject of growing market attention as talk of an eventual IPO continues to build. SpaceX has become one of the most closely watched private companies in the world, with a valuation that has climbed steadily on the back of its dominance in commercial launch services and its expanding satellite internet business.

A short bet against a company of SpaceX’s scale and momentum would be a high-risk, high-conviction move — exactly the kind of trade Burry has built his reputation on, which is part of why his decision to pass is drawing as much attention as the idea itself would have.

Reading Between the Lines

Without elaborating on his specific reasoning, Burry’s comment leaves room for interpretation. It could reflect genuine respect for SpaceX’s fundamentals and growth trajectory, or simply an acknowledgment that shorting a company with no current public listing — and significant insider control — is a structurally difficult trade to execute profitably.

The Takeaway

Whether or not Burry ever acts on the instinct, the episode is a reminder of how much weight markets still place on the views of investors with a track record of contrarian calls — even when, as in this case, the headline is really about a bet that didn’t happen.
