Switzerland’s stock market operator halted equity trading for hours on Wednesday after a technical snag that made it impossible to distribute pricing data, the exchange’s longest outage ever and the second to hit it in little more than a year. The halt began at 10am Zurich time and trading was to resume at 2:30pm, SIX Swiss Exchange said on Wednesday. The exchange hadn’t been able to disseminate market data and indexes since about 9:10am, a spokesperson said. Data for the Spanish stock market, owned by SIX, also was affected for several hours, though trading there continued. The interruption is another reputational hit to the Swiss exchange, the trading venue for some of Europe’s biggest companies, including Nestle SA, Novartis AG and Roche Holding AG. Last year, the market was hit by its worst outage in more than a decade, with dealing in equities and derivative instruments halted for three hours. + From 2023: Swiss stock exchange probes three-hour blackout “It’s never good news ...
