Unlike stocks, you need not wait for any particular time to invest in mutual funds. This is because the fund managers and their team of analysts pick only the right securities and assets at all times and are going to benefit the investors, regardless of the market condition. Also, if you are investing via a SIP, then you are going to benefit from both down and high market cycles. When the markets are down, you end up buying more fund units as the stock prices would have fallen to their fresh lows, and when the markets shoot up, you buy lesser units. This is called the rupee cost averaging. This benefit is available only in the case of investing in mutual funds via SIP. Hence, you need not wait for any particular time to invest in mutual funds. The best time to invest in mutual funds is now!
