European Bourses Struggle Following Wall Street Sell-Off

European stock markets faced challenges on Wednesday in the aftermath of a new-year sell-off on Wall Street. The region's technology sector, in particular, experienced notable pressure as a result of a downgrade for Apple, which caused the sector to decline.

DAX Index Falls 1% in Frankfurt

The DAX index (DX:DAX) in Frankfurt dropped 1%, while the FTSE 100 (UK:UKX) in London marked its 40th birthday with a 0.8% decrease. Miners faced difficulties due to concerns surrounding weakening economic growth.

Paris' CAC 40 Declines 1.4%

The CAC 40 (FR:PX1) in Paris experienced a loss of 1.4%, with train-maker Alstom (ALO) falling 7% in response to Barclays cutting its price target for the company from €8.5 to €8.

Amsterdam's AEX Index Retreats 0.6%

Amsterdam's AEX index (NL:AEX) retreated by 0.6% as chip-equipment makers ASML (ASML) and ASM International (ASM) saw their stocks decline by 2% and nearly 3% respectively. This was influenced by a sector-wide pullback in Asia and the United States.

Tech Sector Profit Taking

Furthermore, Franco-Italian chipmaker STMicroelectronics (STMPA) fell by 2.4% and its German peer Infineon Technologies (IFX) lost nearly 3%. The tech sector, which has performed well recently with ASML up 16.5% over the last three months and ASM International up 82% over the last 12 months, was deemed suitable for some profit taking. This was initiated by a downgrade of Apple (AAPL) by Barclays from neutral to underweight, leading to a broad tech sell-off.

ASML's shares were already under pressure on Tuesday following a report indicating that the United States had pressured the company to cancel the shipment of some machines to China.

"Tech stocks, with their high valuations, are susceptible to even the slightest economic instability or a rise in yields. Additionally, not everyone was participating in this narrow market peak driven by A.I. hype," stated Stephen Innes, managing partner at SPI Asset Management.

Airbus Shares Decrease by 2%
