Legendary investor Michael Burry has further expanded his bearish bets on the semiconductor sector. On July 25 local time, he disclosed his latest portfolio moves in a Substack post, which included increasing his short position in NVIDIA at $210.28 per share. Regarding his rationale for shorting NVIDIA, Burry stated bluntly that current demand is not driven by genuine end customers, and related financing arrangements remain off-balance-sheet and undisclosed, with future revenue 'largely funded through circular financing structures.'
On Monday, concerns emerged that the chipmaker could take on more debt following reports that it was negotiating an artificial intelligence-related infrastructure project valued at over $750 billion. As a result, the cost of insuring NVIDIA’s debt against default hit a record high. According to ICE Data Services, the cost rose by approximately 0.14 percentage points on Monday, reaching an annualized rate of 0.82 percentage points—the largest single-day increase since these derivatives began formal trading in November.
3rd place$SanDisk (SNDK.US)$Closed down 11.02%, with trading volume reaching $27.1 billion.
Semiconductor memory stocks broadly declined on Monday in the U.S. market.
According to MS Hwang, an analyst at Counterpoint Research, in an interview with Benzinga: "Chinese manufacturers are rapidly catching up in the areas of commodity DRAM and NAND. However, it is very difficult for them to overtake in HBM." He added, "I believe Chinese manufacturers could produce HBM3 by the first half of 2027."
4th place $Apple (AAPL.US)$ Rose 1.17%, with trading volume reaching $16.656 billion, bringing its market capitalization close to $5 trillion.
5th place $Advanced Micro Devices (AMD.US)$ Declined 5.17%, with trading volume of $15.584 billion.
In a research report released Monday, Wedbush Securities maintained its "outperform" rating on Advanced Micro Devices and significantly raised its price target, citing strong growth momentum in its data center business across both CPUs and GPUs, as well as demand uplift from newly established artificial intelligence partnerships.
Wedbush expects Advanced Micro Devices’ data center revenue to accelerate from the second half of 2026 through 2027. This outlook aligns with recent signals from AMD CEO Lisa Su, who previously stated that, driven by robust demand for the 'Helios' platform and MI450-series GPUs, the company is confident in achieving multi-billion-dollar annual AI data center revenue by 2027.
Additionally, Mizuho Securities raised its price target for Advanced Micro Devices from $615 to $625 on Monday.
9th place$Alphabet-A (GOOGL.US)$ Gained 2.13%, with trading volume of $9.275 billion.
It was reported that the Office of the National Cyber Director at the White House distributed a draft framework approximately two weeks ago to OpenAI, Anthropic, and Google, and the three companies jointly submitted their proposed revisions. President Trump signed an AI-related executive order in early June, requiring the regulatory framework to be finalized by August 1.
The framework aims to establish standardized procedures to govern next-generation, high-compute AI models capable of rapidly identifying cybersecurity vulnerabilities.
Rank 11$SK hynix (SKHY.US)$ Fell 7.47%, with trading volume of $7.229 billion.
Against the backdrop of a broad sell-off in the semiconductor sector, the stock closed at $143.02 on Monday, marking its lowest closing price since listing and falling below its IPO offering price for the first time.
Although the market remains broadly optimistic about AI’s growth prospects, investors continue to sell semiconductor stocks that surged earlier. Even NVIDIA and$SK Hynix (000660.KR)$announced plans to build an AI data center in South Korea with a total installed capacity exceeding 2 gigawatts, yet their share prices still declined.
Ranked 12th$SpaceX (SPCX.US)$It closed down 1.36%, with trading volume reaching $7.137 billion.
Starlink is currently the company's only business segment generating stable profits, but user growth in the latest quarter has clearly slowed, raising market concerns over limited growth potential. Starship, as the core vehicle for the lunar landing program, satellite constellation expansion, and space-based computing infrastructure, has experienced repeated test flight failures. A recent launch was aborted during the countdown phase due to an engine anomaly, further delaying the commercialization timeline. The company reported a net loss of $4.9 billion for the full year 2025, and its Q1 2026 loss alone reached $4.276 billion—nearly matching the entire prior-year deficit. This massive loss stands in stark contrast to its sky-high valuation. Wall Street short-seller Michael Burry bluntly stated the company is 'not even worth $1 trillion,' while seasoned investors estimate its fair value at approximately $30 per share.
Ranking 17th$ASML Holding (ASML.US)$It closed down 5.80%, with trading volume reaching $5.513 billion.
ASML Holding shares fell as much as 6.4% intraday, hitting their session low. Analysts noted that market concerns over ASML’s growth outlook for 2026 are the primary driver behind the stock’s recent volatility.
U.S. technology media outlet The Information previously reported that a Chinese state-backed enterprise has initiated the development and manufacturing of immersion DUV lithography machines. The report caused market volatility, with investors concerned that ASML Holding's market share could face long-term pressure. According to the report, the equipment is targeted to produce five units in 2026 and scale up to 20 units in 2027. It also stated that if mass production proceeds smoothly, the equipment could become competitive against ASML Holding’s comparable products.
Ranked 18th $Palantir (PLTR.US)$ rose 7%, with trading volume reaching $4.746 billion.
Citi analyst Tyler Radke remains bullish on Palantir, reiterating a “Buy” rating while lowering his price target from $225 to $200. The bank clarified that the reduction does not reflect pessimism. The analyst significantly raised his earnings forecast for Palantir’s fiscal year 2027, projecting revenue growth of 53% year-over-year—well above the Wall Street consensus of approximately 45%.
Market participants noted that Citi analysts’ contradictory move of lowering the target price while raising earnings expectations reflects Palantir’s unique predicament: its fundamentals continue to accelerate, yet its valuation is still digesting the bubble from the past. Palantir will report its latest quarterly results after U.S. market hours on August 3.
