Different funds have different risk-return profiles. You need to choose a fund based on your risk-taking capabilities and the time horizon you have in mind for the investment. So, you need to find a balance between your risk tolerance and the risk of the fund you are planning to invest in. For example, if you are willing to take high risk but your investment horizon is less than 3 years, you shouldn't invest fully in equity funds.
You may consider investing in a mix of equity and debt with more exposure to debt funds. Therefore, you need to choose the best Mutual Fund based on your risk appetite and time horizon.
Please consider talking with an Investment Advisor before making any financial investment.
