Your Net WorthPound-cost averaging
Pound-cost averaging is investing a fixed amount regularly, buying more units when prices are low and fewer when they are high.
In the US the same idea is usually called dollar-cost averaging. The principle is identical: you remove the temptation to time the market by automating a steady contribution.
Pound-cost averaging reduces the risk of investing a large lump sum just before a market fall. It also enforces discipline during volatility, because the same monthly amount automatically buys more when prices drop.
It is not a guarantee of better returns than a lump sum. Historically, markets rise more often than they fall, so investing immediately has usually won. But for many people the behavioural benefit of a regular plan outweighs the statistical edge.
