Dynamic Bond Fund is an actively managed portfolio of debt mutual fund schemes where the allocation of the funds is managed by the fund managers. The funds here are allocated with respect to interest rates of the market. Dynamic Bond Fund is less likely to lose your money as the managers foresee the market and the changing interest rates.
Dynamic Bond Fund forms a good credit quality debt instrument that generally earns reasonable returns and liquidity to the investors. This debt mutual fund scheme varies with the exposure of different investment-grade like debentures, Certificate of Deposit, Bonds, Government securities, etc.

Another advantage of investing in dynamic Bond fund is the investment flexibility. Fund manager has the ease to choose options between short-term and long-term bonds. This can be choosed according the volatile market rates.
I consider Dynamic Bond Funds is good for an investor who are not able to predict the market and invest as per the favorable interest rates.

Few top-performing Dynamic Bond Fund in 2019 I recommend are:
ICICI Prudential Long Term Plan Growth
Franklin India Dynamic Accrual Fund Growth
