Bond funds are also subdivided. Bond funds are divided into pure debt type, partial debt type, stock-debt balance type and bond enhancement type. Pure debt fund 100% invests in bonds, so most of the time, it will make money every day.

However, debt-biased, stock-debt-balanced, and bond-enhanced types will not earn money every day, because some of them invest in the stock market and the stock market is closed on Saturday, Sunday and holidays, so there is no income.
