Mutual fund invests in different investment options like equity, debt, gold, illiquid funds, etc. This is known as diversification, which means that if investment from one option is not giving a good return then other investments give a fair or high return, thus overall minimizing risk. Also, the investment decision is taken by a professional Fund Manager who has in-depth knowledge, skill, and ability to manage the risk of an investment portfolio.
As a common layman, not everybody has enough fund to that can be allocated in different investment avenues. Through Mutual Fund, with a small amount of money diversification is possible and thus reduced a level of risk. Additionally, the investment allocation to every fund is done by professional Fund Manager which otherwise, might be an obstacle to invest even with adequate money. Therefore, I suggest you to consider Mutual Fund to park your investment.
