Semiconductor stocks in Hong Kong are broadly facing selling pressure.

At the time of writing, Montage Tech (06809.HK) was down 5.96% at HK$382. Gigadevice (03986.HK) fell 5.53% to HK$742.5. HUA HONG SEMI (01347.HK) declined 2.24% to HK$153, while SMIC (00981.HK) dropped 2.27% to HK$79.25.

The weakness follows an overnight decline for most U.S. chip stocks, with the Philadelphia Semiconductor Index closing down over 2%. Broadcom plunged more than 12% and Micron Technology tumbled over 7%.

Broadcom's latest revenue figures came in slightly below market expectations, casting a shadow over the AI investment boom that has been driving the market. This has led investors to reassess whether future growth expectations for AI infrastructure investment have already been priced in.

In other news, a recent report from SemiAnalysis noted significant adjustments to the memory configuration in Nvidia's next-generation AI server cluster, Rubin NVL72. To address supply chain constraints and ensure timely delivery of Rubin cabinets, the per-cabinet capacity has been drastically reduced from the originally planned 55TB to 28TB, a reduction of approximately 50%.

Regarding this, Dylan Patel, founder, CEO, and lead analyst at SemiAnalysis, stated: "I love it when people share what we said but miss most of the report. Our original report did not use that clickbait headline."
