Arizona Tribune - Stock markets limp into weekend as AI bubble fears grow

After some equity indices hit record highs, along with gold and bitcoin, "the bull run is on pause", noted Derren Nathan, head of equity research at Hargreaves Lansdown.

European and Asian stock markets were largely downbeat Friday after losses Thursday on Wall Street.

The dollar traded mixed against main rivals and oil prices slid more than one percent.

Nathan added that "the great reality check, otherwise known as third-quarter earnings season, is upon us".

Buying sentiment won a boost this week from news that ChatGPT-maker OpenAI had signed multi-billion-dollar chip deals with South Korean titans Samsung and SK hynix as well as US firm AMD.

The spending added to the hundreds of billions already pumped into the sector as firms look to get ahead on the sphere of artificial intelligence.

That in turn has seen investors flood into the tech sector, sending stock prices rocketing -- with US chip leader Nvidia topping a $4 trillion market capitalisation.

However, there are rumblings that the rally could run out of steam, causing jitters on trading floors.

"Some areas of the market appear overheated," said Keith Lerner at Truist Advisory Services.

Such worries have been part of the reason behind the rally in gold to a record above $4,000 an ounce Wednesday.

Alexandra Symeonidi, corporate credit analyst at William Blair, wrote: "Given the strong rally in tech stocks some market participants started to question the sustainability of the price momentum and were driving parallels with recent bubbles.

"So, while the overall market has been healthy, investors have been adding hedges in what is broadly considered to be a safe haven asset."

Still, Pepperstone's Michael Brown remained upbeat on equities and saw plenty of upside.

"My view remains that dips in the equity complex should still be viewed as buying opportunities, with the 'path of least resistance' continuing to lead higher amid resilient underlying economic growth, robust earnings growth, and a looser Fed policy backdrop," he wrote in a commentary.
