Overview & Core Concept
Lumpsum investing involves depositing a single bulk sum into an investment vehicle such as an equity mutual fund, index ETF, or fixed-income deposit.
Academic research consistently demonstrates that "time in the market beats timing the market". Lumpsum investments benefit from having the full principal earning compound returns from day one.
