Does lumpsum always beat SIP?
Studies of the Indian market show lumpsum outperforms SIP approximately 65-70% of the time over 10+ year periods because more money compounds for longer. However in the 30-35% of cases where markets decline after investment SIP significantly outperforms. Since predicting market direction is nearly impossible for most investors SIP remains the safer default strategy.
What is STP and how does it combine both?
A Systematic Transfer Plan is the best of both worlds. You invest your lumpsum in a liquid or debt fund and set up automatic monthly transfers to an equity fund. This gives you the safety of gradual equity exposure while your money earns 6-7% in the liquid fund instead of sitting idle. Most investors with a lumpsum above Rs 5 lakh should use STP.
When should I choose lumpsum over SIP?
Choose lumpsum when you have a time horizon of 7+ years and markets are at reasonable valuations (Nifty PE below 20). Also choose lumpsum for debt funds FDs and other low-volatility instruments where timing matters less. For regular monthly income from salary always use SIP as it matches your cash flow pattern naturally.
