Chinese Chipmakers Rally Before Nvidia Results, Samsung Risk

Key Moments

Chinese Semiconductor Stocks Extend Strong Outperformance

Chinese semiconductor shares advanced sharply on Wednesday as traders increased exposure to the sector on rising confidence in the country’s artificial intelligence capabilities and in anticipation of key industry developments.

Buying interest concentrated in leading chipmaking names ahead of multiple near-term catalysts for the global semiconductor space. NVIDIA Corporation (NASDAQ: NVDA) was scheduled to release its quarterly earnings later in the day, while Samsung’s (KS: 005930) South Korean chip manufacturing operations were expected to begin a strike from Thursday.

Notable Moves in Chinese Chipmakers

Among the most actively traded names, Semiconductor Manufacturing International Corp (HK: 0981), described as China’s largest chipmaker by capacity, climbed 12% in Hong Kong. Hua Hong Semiconductor Ltd (HK: 1347) performed even more strongly, rising nearly 14%.

On the mainland, Cambricon Technologies Corp Ltd (SS: 688256) and NAURA Technology Group Co Ltd (SZ: 002371) also participated in the rally, gaining 2.5% and 5.7%, respectively.

Speculation on Technology Breakthrough and Samsung Strike Impact

The sector’s advance was supported by social media commentary suggesting that China had reached a milestone in 3 nanometer chipmaking technology. However, there were no immediately available verifiable reports confirming such a development.

Market participants also positioned around the potential implications of labor action at Samsung. Expectations that a strike could disrupt some of Samsung’s operations prompted speculation that Semiconductor Manufacturing International Corp and Hua Hong, identified as China’s largest foundries, might capture incremental business.

According to South Korean media, the planned strike at Samsung is anticipated to reduce global DRAM and NAND production by between 2% and 4%.

Although Semiconductor Manufacturing International Corp and Hua Hong are described as trailing Samsung in advanced-node foundry work, particularly at the 3/4nm level, they are viewed as potential providers of additional capacity in larger, more established nodes. This scenario represents a possible opening for both firms at a time when global memory availability is already constrained by elevated demand tied to artificial intelligence.

Nvidia Earnings in Focus as Global Chip Stocks Consolidate

Chinese chipmakers outperformed many international peers on Wednesday as the broader semiconductor sector consolidated ahead of NVIDIA Corporation’s earnings release, which is being closely watched by investors.

The company, referred to as the world’s most valuable, is widely expected to deliver another very strong quarterly update. Market attention is centered on whether management will indicate that the current strength in the AI-related trade can be sustained.

Rising optimism about AI-driven chip demand pushed semiconductor stocks to record levels last week. This momentum paused as some investors locked in profits earlier in the week and a recent rise in bond yields weighed on risk assets.

Performance of Key Nvidia Suppliers and Global Peers

Shares of several prominent Nvidia suppliers moved lower on Wednesday. Taiwan Semiconductor Manufacturing Co (TW: 2330), commonly known as TSMC, and Hon Hai Precision Industry (TW: 2317) each fell by up to 2%.

Samsung, which is also a major player in the chip sector, declined 2%. In Japan, Advantest Corp. (TYO: 6857) slipped nearly 1%.
