European Shares Slide Amid Weak Earnings and Political Uncertainty

European shares dropped on Tuesday, influenced by weaker performances in metal mining and luxury retail. Notably, Rio Tinto and Hugo Boss saw significant declines. Political developments in the U.S., including an attempted assassination of Trump and his nomination of J.D. Vance as running mate, also impacted investor sentiment.

European shares fell on Tuesday following weakness in metal miners and dour earnings from luxury retailer Hugo Boss, while markets also assessed the chances of Donald Trump winning the U.S. presidential race.

The pan-European STOXX 600 was down 0.5%, as of 0840 GMT. The basic resources sub-index led sectoral declines with a 1.7% fall as it tracked easing copper prices. Adding to the sector's losses, London-listed shares of Rio Tinto fell 2.5% after the global mining giant reported second-quarter iron ore shipments below estimates.

Shares of Hugo Boss tanked 8.4% after the German fashion house cut its annual sales forecast over weakening global consumer demand especially in markets such as China and the UK. The stock pulled the personal and household goods sector down 0.6%.

Market focus continued to be on political developments in the United States. Investors assessed the fallout from the attempted assassination on Saturday of Trump, who nominated J.D. Vance on Monday as his vice presidential running mate. "The idea that Trump could win a second term in office is being interpreted as negative for European stocks - mostly because of protectionist policies that Trump could put into place," said Fiona Cincotta, senior market analyst at City Index.

"Tie that into the fact that the Federal Reserve could potentially be cutting interest rates in September - that's also helping U.S. stocks to stand out over Europeans shares right now." The European Central Bank will hold its policy meeting later this week, where it is widely expected to hold interest rates. Investors will however focus on remarks from policymakers to ascertain the timing of future rate cuts.

French reinsurer Scor plunged 28% to its lowest since December 2022 after cutting forecast for its life and health unit. The stock dragged the insurance sub-index down 1.2%. Ocado jumped 14.6% after the British online grocer and technology group lifted its annual forecast, citing an improvement in the profitability of its warehouse technology business.

Swedish banking group SEB rose 3.6% on reporting a better-than-expected quarterly profit and maintaining its annual cost outlook, as other revenue streams helped offset pressure from an easing interest income momentum. On the data front, Italian EU-harmonised consumer prices (HICP) rose 0.2% month-on-month in June and were also up 0.9% from the year earlier, confirming preliminary data.
