Major US stock indexes experienced a retreat on Tuesday, with the S&P 500 declining by 0.4%, the Nasdaq Composite dropping 1.2%, and the Dow Jones Industrial Average falling 0.2%. These declines largely reversed some of the gains seen on Monday and were significantly influenced by a sharp slump in artificial intelligence (AI) stocks. The technology sector, particularly AI-related shares, faced downward pressure due to concerns over elevated valuations.

In Europe, stock markets traded flat. The technology sector, similar to its US counterpart, was weighed down by caution surrounding the high valuations of AI stocks. Conversely, defence stocks experienced a marginal increase, with investors closely monitoring a NATO summit for potential indications of increased defence spending. Meanwhile, Australian shares remained little changed on Tuesday. Losses in gold miners and consumer stocks offset gains in the banking and technology sectors. WiseTech Global saw a notable jump in its stock price following the announcement of a new chair. Investors globally were also focused on the release of US Federal Reserve minutes and ongoing geopolitical tensions.

The broader market sentiment appears to be shaped by a cautious approach to AI stock valuations, a watchful eye on geopolitical developments, and anticipation of economic indicators such as the US Federal Reserve's meeting minutes. The performance of different sectors, from technology and defence to mining and consumer goods, reflects a mixed investment landscape influenced by both specific company news and macroeconomic factors.
