Found a fund? Now check if it fits 

The choice of a best Lumpsum Mutual fund is not based on the performance of previous years. Instead, it’s all about ensuring that the fund fits your goals, risk profile, and investment horizon.

Consider these questions before investing in a specific lumpsum mutual fund:

  • What would be my investment tenure?
    • Less than 3 years → consider debt or hybrid.
    • Above 5 years → equity (flexi-cap, large-cap, selective mid-cap) works.
  • How volatile can I take it?If a 20-30% drop in portfolio value makes you lose sleep, better not go for a small/mid cap fund in lumpsum.
  • Diversification or double down?In case you are heavily invested in a certain sector or theme, avoid using lumpsum for investing in that area again.
  • Have I checked the basics?Here are the things to consider:
    • Consistency of returns (3Y, 5Y, since inception)
    • Expense ratio
    • Concentration of portfolio (Top 10 positions).
    • Manager’s experience.

Final word

Lumpsum investment is quite similar to the feeling of putting everything on the line. What happens if things don't go as planned? However, success in investing does not lie in discovering a fund that beats the market at all times. 

This is about picking the right fund and having patience. Some of these funds in this best Lumpsum Mutual fund list are focused on growing through midcaps, while some are theme-driven like infrastructure and PSUs.

Each has its pros and cons. When investing, don’t just look at the performance figures. See what the fund’s investment strategy is, how risky it is, and if it suits your plans. As lumpsum investments usually benefit from one factor the most, that is time.
