Asian stocks ended mixed as AI data centre stocks and regional chipmakers slumped on expectations of tighter tech oversight. Investors were reacting to the prospect of a Democratic-led US Congress tightening rules on AI development and data centre construction.
Why Did Advantest and Tokyo Electron Fall Today?

The worry is a possible slowdown in capital expenditure. Traders bet Democrats will slow the pace of data centre expansion in the US.
– **Advantest** (chip testing equipment) plunged 14.7%.
– **Tokyo Electron** (chip equipment) declined 9.4%.
– The **Nikkei** dropped 1.79% to 61,077.90, while the broader **Topix** settled 1.16% higher at 3,940.39.
How Far Did the Kospi Fall on Chip Selling?
Seoul stocks nosedived as chipmakers plummeted. Concerns centred on tighter US regulation of AI infrastructure curbing data centre investment and weakening semiconductor demand.
The **Kospi** plunged 5.28% to 5,383.80. Foreign investors extended their selling streak to a fifth session.
Which Markets Gained While Tech Slid?
The **Hang Seng** surged 3.67% to 24,796.98, led by **Alibaba** and **Tencent**. In Shanghai, the **Shanghai Composite** edged up 0.1% to 3,689.91, extending a rebound for a second day after top financial regulators announced measures to inject liquidity.
In Australia, the **S&P/ASX 200** surged 2.61% to 9,065.10, hitting a two-month high. The **All Ordinaries** closed 2.8% higher at 9,205.20, with IT, retail, real estate and healthcare stocks leading.
New Zealand’s **S&P/NZX-50** climbed 2.23% to 14,090.97. That was its best single-day gain in nearly 19 months and an all-time high.
How Did Oil and Gold Move on the US-Iran Conflict?
**Brent crude** rose 0.5% to US$95.08 a barrel in Asian trade. The contract had fallen nearly 9% in the previous session, which is about RM384.42 at the US$95 level quoted in the report.
The drop followed Democrats’ sweeping victory in the US midterm elections and diplomatic signals from Washington and Tehran. Those factors helped strip the risk premium out of crude.
**Gold** rose nearly 2% to US$4,125 an ounce. It posted its biggest jump since August on Wednesday as the dollar and Treasury yields slipped.
What Does This Mean for Bursa Malaysia Investors?
The report names no Malaysian stock, so no Bursa stock code is affected directly. Two related Malay Mail headlines from the same news feed point to local conditions. Bank Negara held the OPR at 2.75%, and Bursa Malaysia closed higher on that decision. The **ringgit** extended its gains at the close.
For Malaysian holders of regional tech exposure, the key number to track is the pace of any US AI rulemaking. Investors may want to watch how the Kospi and Advantest moves compare with Bursa’s technology names over the coming sessions. Those comparisons will show whether the sell-off stays confined to chipmakers. For more on screening stocks with data, see AI Stock Analysis for Malaysians.
