Core Viewpoint - The article emphasizes the opportunity for investors to utilize idle funds during the National Day holiday by engaging in government bond reverse repos, which can yield interest over the holiday period without risk [1][2]. Group 1: Investment Strategy - Investors can earn interest for 9 days by executing a 1-day reverse repo on September 29, with funds available for withdrawal before the market opens on October 9 [2][4]. - The optimal operation date for reverse repos during the National Day holiday is September 29, allowing investors to maximize interest earnings [3][4].
