While it is always a great idea to diversify your investment portfolio, you must ensure that you do not park money in a large number of mutual funds. This is essential to avoid the inclusion of too many under-performing funds in your portfolio, which could bring poor results. For instance, with large number of funds, multiple SIPs are deducted on different dates of the month. So, you may not have sufficient balance in your bank account for payment towards SIPs on particular dates. Also remember, not to invest all your money in one scheme. Start small, and gradually increase the investment amount as you understand how this works.
