QBIT.SW is trading at CHF 19.80, -3.18%, as lingering repricing follows memory-stock selling after Samsung’s preliminary third-quarter sales and operating-profit forecasts missed analyst estimates. - The October 8 selloff weighed on major memory and storage shares; Samsung and Micron are significant benchmark holdings. - Higher oil prices and Treasury yields pressured chip valuations in the prior session. Memory shares reportedly rebounded in premarket trading on October 9, but the ETF quote remained lower, potentially reflecting Swiss-market timing and holdings repricing.
