Value averaging (VA), also known as dollar value averaging (DVA), is a technique for adding to an investment portfolio that is controversially claimed to provide a greater return than other methods such as dollar cost averaging. With the method, investors add to (or withdraw from) their portfolios in such a way that the portfolio balance reaches a predetermined monthly or quarterly target, regardless of market fluctuations. For example, an investor may want to have a $3600 investment in 36 months. Using VA, the investor would aim to have a total investment value of $100 at the beginning of the first month, $200 at the beginning of the second month, and so on. Having invested $100 at the beginning of the first month, the investment may be worth $101 at the end of that month. In that case, the investor invests a further $99 to reach the second month objective of $200. If at the end of the first month, the investment is worth $205, the investor withdraws $5.
