Lumpsum Capital Compounding: Accelerating Long-Term Wealth with One-Time Deployments

Lumpsum Investment FAQs
Strategic answers on deploying one-time capital into Indian equities.
Should I invest a large lump sum in one go or route it via an STP?
If equity markets are trading at elevated valuation multiples, parking the lump sum in an overnight or liquid fund and setting up a 6 to 12-month Systematic Transfer Plan (STP) into equity funds cushions against short-term market pullbacks.
How long does a lumpsum investment take to double in mutual funds?
Using the Rule of 72: divide 72 by your expected annual return rate. At a 12% CAGR, your lumpsum investment doubles approximately every 6 years (72 ÷ 12 = 6).
