ASML Holding NV shares showed a stable performance entering the Christmas trading break on December 24, with U.S.-listed shares advancing by 0.35% to $1,065.52 on NASDAQ. European shares on Euronext Amsterdam closed slightly lower, declining by 0.47% to €899.00, with this divergence attributed to currency effects and holiday timing. The company's ongoing share repurchase initiative, which saw nearly 200,000 shares acquired between December 15 and 19, provided a stabilizing floor during low pre-holiday trading volumes. ASML maintained its position above the $1,050 support level.
