European shares opened lower for a third straight session on Wednesday, weighed down by losses at Dutch semiconductor company ASML after announcing forecasts for the year.
Pessimistic, as traders assess the possibility of the US imposing strict trade rules.
By 0717 GMT, the pan-European STOXX 600 index was down 0.3%, with the technology sub-index down 1.9%.
ASML shares fell 5.3% after chipmaking equipment supplies fell short of third-quarter sales estimates.

Shares of other semiconductor companies also fell, including ASM International and BE Semiconductor, which each fell more than 2%.
Meanwhile, Adidas shares jumped 4.5% after the German sportswear maker raised its full-year profit forecast following better-than-expected second-quarter results.
Shares of its competitor, Puma, gained 2.5%.
Markets are also awaiting final euro zone inflation data for June due at 0900 GMT, ahead of the European Central Bank's interest rate-setting meeting later in the week.
