Group 1: Investment Strategy - Investors are encouraged to perform a one-day reverse repurchase agreement (repo) before the holiday, which allows them to earn interest for the entire 11-day holiday period [1]. - The first step involves executing a one-day reverse repo on February 12, which will generate interest for the duration of the holiday [1]. - The second step is to invest the returned funds into the government bond ETF (511580) on February 13, which will also start accruing interest from the next day [2][3]. Group 2: Benefits of the Investment - By utilizing both the reverse repo and the government bond ETF, investors can earn dual returns: interest from the reverse repo and coupon payments from the ETF during the holiday [3]. - The government bond ETF is highlighted for its high safety due to its underlying assets being government bonds and policy financial bonds, which carry minimal default risk [5]. - The ETF has a historical annualized return of 2.49%, significantly higher than typical money market funds, making it an attractive cash management tool [5]. - The ETF features low fees, with a management fee of 0.15% per year and a custody fee of 0.05% per year, maximizing investor returns [5]. - The ETF offers strong liquidity with T+0 trading, allowing investors to sell at any time after the holiday without delay [5].
