Question 1

What is dollar value averaging?

Accepted Answer

Instead of investing a fixed amount, you target a fixed portfolio value each period and buy (or sell) the difference. When prices fall you invest more; when they rise you invest less — automatically buying low.

Question 2

How is it different from DCA?

Accepted Answer

DCA invests a constant dollar amount regardless of price. DVA varies the amount to keep the portfolio on a target growth path, so it leans harder into dips — potentially better returns, but it needs more cash in downturns.
