On May 14, Ping An's medium- and high-grade corporate bond spread factor ETF under Ping An Fund exceeded 10 billion yuan, reaching 10.017 billion yuan, making it the third largest bond ETF in the entire market. In the current environment of easy liquidity and low interest rates, credit bond products are increasingly popular among investors. Since this year, Ping An's medium- and high-grade corporate bond interest rate spread factor ETF size has increased by about 4 billion yuan, and the scale has increased by more than 2 billion yuan in the past month. According to public information, this ETF is the first smart beta bond ETF and the first medium to high grade credit bond ETF in China. It is preferred to select the Shanghai Stock Exchange's listed entity/debt double AAA, implying corporate bonds of AA or above. It is positioned as a credit bond broad base and a central enterprise corporate bond, and efforts are being made to build the Shanghai Stock Exchange's “blue chip debt” core tool.
