European stock markets showed little movement on Wednesday, with positive results from Richemont boosting the luxury goods sector, offset by declines in mining and telecom shares.

The pan-European STOXX 600 index closed with a marginal gain of 0.1%. An index tracking the region's luxury stocks climbed 3.2%, lifted by a 6.7% surge in Richemont after the Swiss jeweller reported first-quarter sales growth that was nearly double expectations.

The mining sector was weighed down by industry giants Anglo American and Rio Tinto. The telecoms sector faced pressure from Nokia. The chemicals sector also declined, with BASF shares falling 3.0% as the company's raised profit forecast failed to impress investors.

The European benchmark has largely traded sideways this week as investors weigh a strong earnings season outlook against simmering US-Iran tensions. Corporate results are in focus, with the number of analysts raising profit forecasts compared to those lowering them reaching a near five-year high.

Stephan Kemper, Chief Investment Strategist at BNP Paribas Wealth Management, stated that the region "remains a stock picker's paradise."

However, he also noted that European equities continue to face multiple headwinds, including limited substantive exposure to artificial intelligence, weak growth, intensifying market competition, and the risk of energy prices staying elevated for longer.

In other corporate news, Swedish retailer Axfood AB saw its shares drop 14% after its operating profit fell short of expectations.
