Tech Rout Hits Wall Street as AI Trade Shows Signs of Fatigue

Last update - 18 December 2025 By James Woods

United States

A tech rout hammered Wall Street overnight, with the S&P 500 sliding 1.2 per cent to fall below its 50-day moving average for the first time in months. The Nasdaq 100 tumbled 1.9 per cent, led lower by Nvidia, which dropped 3.8 per cent. The Dow Jones Industrial Average fell 0.5 per cent.

The selloff accelerated after news that Blue Owl Capital, a longtime partner in Oracle’s rapid AI infrastructure buildout, opted not to contribute equity for a data centre in Michigan. While the project is largely moving forward, the news was enough to rattle investors already nervous about lofty tech valuations. Oracle shares plunged about 5.5 per cent, extending a brutal stretch that has seen the stock tumble around 22 per cent from its recent high.

Tesla was the worst performer among the megacaps, sliding more than 4 per cent despite being near 20 per cent above its November low. Six of the seven “magnificent” tech giants finished lower, with Microsoft the only one to edge higher.

The UBS US AI Winners Index tumbled 3.3 per cent, underscoring the growing concern over whether the sector can keep justifying its ambitious spending and stretched valuations.

Bonds bounced from session lows after Fed Governor Christopher Waller signalled support for further rate cuts, saying monetary policy settings are up to 100 basis points above neutral. Waller, who is under consideration to be the next Fed chair, was expected to meet with President Donald Trump on Wednesday. The yield on 10-year Treasuries was little changed at 4.15 per cent.

The market is now entering what analysts describe as a rotation period rather than a correction, with money flowing out of overvalued tech stocks into energy, consumer staples and healthcare. Since the near-term low on November 20, the small-cap Russell 2000 has gained about 8 per cent while the Magnificent Seven index rose just 4.5 per cent.

In late trading, Micron Technology gave an upbeat forecast, which may provide some relief when markets reopen.

Schneider Electric fell 3.4 per cent, Siemens dropped 2 per cent, and ABB lost 1.9 per cent on concerns about a potential slowdown in data centre buildout.

UK firms outperformed after inflation slipped to its lowest level in eight months, all but sealing an interest rate cut at the Bank of England on Thursday.

Banks rallied to a fresh 2008 high, led by HSBC which gained 2.7 per cent to a record after an upgrade highlighting the strength of its Hong Kong business. Societe Generale jumped 3.9 per cent.

Defence stocks bucked the broader industrial weakness after Germany approved a landmark €50 billion in military purchases. Rheinmetall rose 1.7 per cent, BAE Systems added 1 per cent, and Kongsberg climbed 2.4 per cent after winning a contract for navigation systems from the German Navy.

Miners were boosted by rising copper, gold and iron ore prices, with Rio Tinto up 1.6 per cent and Anglo American gaining 1.8 per cent.

Diageo agreed to sell its majority stake in East African Breweries to Japan’s Asahi Group Holdings for $US2.3 billion as the struggling UK distiller streamlines operations.

The local market faces a subdued open, with S&P/ASX 200 futures pointing to a marginal decline. ANZ and Elders are holding annual meetings today.

ANZ chairman Paul O’Sullivan faces a showdown with shareholders after proxy votes showed 32.36 per cent voted against the bank’s remuneration report, delivering a “second strike” in a pre-Christmas blow to the board.
