| InvestHub.com's Finance Dictionary and Glossary of Investment Terms Advance/Decline Line - A/D Definition 1.
A technical analysis tool representing the total of differences between advances and declines of security prices. The advance/decline line is considered the best indicator of market movement as a whole. Stock indexes such as the DJIA only tell us the strength of 30 stocks where as the A/D line provides much more insight. |
