World stocks dipped on Tuesday as renewed AI concerns hit high-flying chipmakers and drove investors to the ​safety of government bonds, while big Wall Street banks kicked off the US quarterly reporting season.

The spotlight is on chipmaker ​Micron Technology as it prepares to report earnings, and investors are bracing for more volatility after recent market swings fueled by large flows ‌tied to SpaceX and a two-day boom-bust in semiconductor stocks.

The Nasdaq Composite and the S&P 500 lost ground on Tuesday under ​pressure from technology stocks, while the Dow Jones Industrial Average touched a record high and SpaceX surpassed Amazon's market value to become ‌the fifth-most valuable U.S. company.

The S&P 500 ended lower on Thursday, with Intel and other chip stocks retreating ​after a recent rally, while uncertainty around U.S.-Iran peace talks weighed on the wider market.

UK stock indexes were swept up ​in a global selloff on Monday, as an escalating military conflict in ‌the Middle East fuelled a jump in oil prices and drove investors towards safe-haven assets.

U.S. stocks closed higher on Friday after a rocky start to the week, as a rebound in technology shares offset tumbling consumer stocks such as Nike.

French stocks rose to a seven-month high on Thursday after the government survived a confidence vote, while a jump in Nestle buoyed the wider European market.
