TSMC (TSM.US) plans to raise prices for advanced-node and mature-node chip foundry services by as much as 10% next year, reflecting rising costs for materials, manufacturing equipment and construction of new overseas chip plants, Nikkei reported, citing sources. Spurred by the news, TSMC ADRs spiked 3.5% in pre-market trading.

TSMC reportedly discussed the price increases with customers, involving 7-nm and more advanced process technologies, which accounted for about 77% of the company's 2Q revenue. Sources said the base price increase ranges from 5% to 10%, depending on customers and products.

For mature processes including 12-nm, 16-nm and 28-nm technologies, TSMC plans to raise prices by as much as 10%. Sources said negotiations on the price increases began last month and will be finalized in July, with the new pricing taking effect at the beginning of next year.

TSMC's major customers include NVIDIA (NVDA.US), Apple (AAPL.US), Google, Amazon (AMZN.US), Qualcomm (QCOM.US), ARM (ARM.US) and MediaTek, among other leading chip developers.

UBS said in a report that the selloff in momentum stocks may be nearing an end, creating opportunities for investors to start rebuilding positions in AI and semiconductor stocks.

On Tuesday (21st), China's STAR 50 Index surged more than 9%, while South Korea's tech-heavy KOSPI and Taiwan Stock Exchange Weighted Index also rallied more than 3-4% as capital started flowing back into AI-related stocks.

UBS said part of the reason for the bottoming of the tech sector is that most speculative positions have already been unwound. Hedge funds reduced long positions in momentum and semiconductor stocks by an amount equivalent to 5% of total market cap, bringing net positions in semiconductor and software stocks back to April levels.

UBS believed improving AI fundamentals signal a buy-on-dip opportunity and recommended investors gradually rebuild positions rather than rushing into the market all at once. The bank's current momentum stock portfolio includes Sandisk Corporation (SNDK.US), Broadcom Inc. (AVGO.US), Oracle Corporation (ORCL.US), KKR & Co. Inc. (KKR.US), Datadog, Inc. (DDOG.US) and Microsoft Corporation (MSFT.US).

Z.AI (02513.HK) has recently completed a large-scale data center with a designed power capacity of 1 gigawatt, fully adopting domestically produced AI chips, according to Bloomberg, citing sources.

The move marks a key step for Chinese AI companies in promoting localization, shunning reliance on products from NVIDIA Corporation (NVDA.US), and building independent computing power infrastructure.

The data center has reportedly partially commenced operations to support the development of its advanced GLM platform. Z.AI has built or operated multiple computing clusters within the facility, with each cluster equipped with more than 10,000 chips.

Tesla (TSLA.US) will announce its second-quarter results on Wednesday (22nd), with the market believing the EV legacy is facing an increasingly challenging operating environment.

Despite a seemingly resilient macro environment, a combination of fundamental headwinds, competitive pressure and elevated valuation expectations has led the market to see higher downside risks ahead of the earnings release.

Tesla previously reported second-quarter sales and delivery data that easily exceeded market expectations, yet the share price subsequently declined.

The share price reflects alarmingly high market expectations, where outperforming expectations has become the minimum requirement. If beating delivery targets still fails to drive the stock higher, even earnings merely meeting or slightly beating expectations may still trigger a muted response from Wall Street.

Alphabet Inc. (GOOGL.US), the parent company of Google, rose 1.5% on Monday (20th) after The Information reported that the company is developing a new server chip internally codenamed "Frozen v2" to run Gemini models more efficiently.

The chip will permanently embed certain Gemini architecture functions into the silicon chip to reduce the amount of computation and data movement required to respond to queries, according to the report.

The company reportedly aims to deploy the chip in 2028, with the project intended to ease severe internal computing capacity shortages, which have reportedly wrought internal tensions and forced Google Cloud to reject some external business.

Despite ASML (ASML.US) and TSMC (TSM.US) delivering exceptionally strong results for 2Q26 and providing upbeat guidance, global semiconductor stocks remain under pressure, CLSA said in a report.

The PHLX Semiconductor Sector Index has ebbed back 20% from its June peak, while South Korean memory giants Samsung Electronics and SK Hynix have plunged 30% and 37%, respectively. Market concerns are centered on the sustainability of AI capex.

Furthermore, Chinese AI models such as Kimi 3 are rapidly narrowing the performance gap with top-notch US models at lower costs, which may affect demand for computing power and memory, according to recent media reports.

The broker reiterated High Conviction Outperform on SK Hynix (000660.KS), with a target price of KRW3.7 million. It also reiterated Outperform on Samsung Electronics (005930.KS) and Micron Technology, Inc. (MU.US), with target prices of KRW540,000 and USD1,700, respectively.

SK Group Chairman Chey Tae-won said global semiconductor demand will mushroom next year, with demand in the AI sector expected to rally 60-100% YoY, while overall semiconductor product demand will also climb at least 50-60%, Yonhap News Agency reported.

However, as additional supply next year is expected to be close to zero, the supply shortage situation may exacerbate further.

Last Friday (17th), the three major US stock indices came under pressure, with the Nasdaq closing down 1.4%. This morning (20th), South Korea's KOSPI traded softer, down 0.66%, while SK Hynix shares jumped up more than 2% and Samsung Electronics gained 0.4%.

Chey said the current global supply-demand situation for memory chips is almost in chaos. As various parties scramble to secure supply, the memory chip supply issue has escalated into a matter of national security.
