You can choose an investment product based on your risk profile and the time it can take to reach your goals.
For example, when it comes to tax-saving, there are four options.
However, the one that might be suitable for your goal depends on your risk-taking capacity. In the early years of investing, you have more years to retire. Therefore your risk-taking capacity is also higher.
In these years, you can choose investments like ELSS for tax savings.
Therefore, you can invest in less risky investments like PPF, FD or NSC during this life stage.
