Lump-Sum Investing
Also called: lump sum investing, investing all at once
Lump-sum investing puts the whole amount to work immediately rather than spreading it over months. Because markets rise more often than they fall, it beats dollar-cost averaging roughly two thirds of the time, and by a meaningful margin on average. Dollar-cost averaging still wins on a criterion the maths ignores: it reduces the maximum regret if the market drops right after you invest, and an investor who panics and sells has lost far more than the expected-return difference.
