ASML Holding could raise its outlook for the year once again when it reports second-quarter results on July 15, UBS analysts write in a note to clients. The Dutch supplier of semiconductor-making equipment expects sales between 36 billion and 40 billion euros this year. Analysts say the group could shift its guidance toward the upper end of the range, or potentially slightly above, as demand for chip-making equipment keeps growing. ASML expects a gross margin--a closely watched metric of pricing power and profitability--between 51% and 53%. Analysts say they see scope for a modest upgrade toward the high end of the range. ASML shares trade 0.5% higher at 1,729 euros. (mauro.orru@wsj.com)
