Bond interest. If you buy bonds with higher coupon, it is about 7% now. Private debt can reach about 10%, but I don't know if the fund can invest in private debt.

Bid-ask spreads earn spreads by buying low and selling high, but this is more difficult, especially since bond prices have fallen sharply this year.

Do a repurchase. However, the market repurchase rate is not high, about 6% at the end of the year.

Play new shares or hold some shares. Some bond funds can hold a share of up to 20%, and if the share rises sharply, the net value may rise rapidly.

The above rates of return cannot be added directly, but can only be multiplied by the rate of return according to the proportion of each investment in the net value. If you amplify the lever, you can amplify the gain or loss.

I checked, the bond fund with the highest yield in 20 13 years is only 12.85%, the second is 1 1.37%, the third is 9.04%, and the others are below 7%. The first major source of income is stock income.
