European stock markets pulled back, dragged down by disappointing financial results from Hermes International SA and Kering, alongside a decline in ASML Holding NV, which weighed on overall market sentiment.

The Stoxx Europe 600 index closed down 0.4% on Wednesday. Shares of Hermes International SA plunged 8.2% as sales were impacted by the war in the Middle East. Kering Group dropped 9.3%, reflecting disappointing sales performance from its brand Gucci. Dutch chip equipment giant ASML Holding NV fell 4.2%, as its strong earnings report failed to impress investors following a 33% surge in its share price this year.

The European earnings season has commenced on a weak note this week, with luxury sector leader LVMH also reporting results that fell short of expectations. Market concerns persist regarding overly optimistic profit expectations, which remain vulnerable to pressures from rising energy costs and weakening consumer confidence. Since the outbreak of the Iran conflict, the pan-European benchmark index has still declined by a cumulative 2.6%, while the S&P 500 index has managed to recover its losses.

Strategists at UBS Group, including Gerry Fowler, anticipate that cost pressures will continue to hinder corporate profits in the region. The team reaffirmed their year-end target of 630 points for the Stoxx Europe 600 index, noting that with valuations no longer cheap, the protective buffer for stocks would diminish should earnings disappoint.

Geopolitical tensions remain a key focus, with the US and Iran reportedly considering extending the current ceasefire by another two weeks.

"The phase of easy gains appears to be over, and fundamentals are set to reassert their dominance in the market," said Emmanuel Cau, Head of European Equity Strategy at Barclays. "For investors focused on fundamentals, earnings performance will be the critical factor in deciding whether to chase the rally or sell into strength."
