The 225-issue Nikkei stock average’s buoyant performance continued Monday, closing at 39,233.71 to set a new all-time closing high for the second consecutive trading day.

Markets were closed on Friday for a public holiday, but this failed to slow momentum, with the Nikkei up 135 points on Monday. The index had opened at 39,320.64, before dipping slightly in the afternoon.

Still, semiconductor-related businesses including Advantest and Tokyo Electron dipped slightly following a boost last week, along with SoftBank Group, while Uniqlo operator Fast Retailing benefited from the rally, edging up 0.86%.
