A-D

Advance-Decline, or measurement of the number of issues trading above their previous closing prices less the number trading below their previous closing prices over a particular period. As a technical measure of market breadth, the steepness of the AD line indicates whether a strong bull or bear market is under way.

A-D

In technical analysis, a line plotting the advance-decline index over a period of time. The advance-decline index takes the total of stock issues increasing on a trading day and subtracts the number of stock issues declining on the same day. Technical analysts use the index as an indicator of market movements, and use the advance-decline line to confirm a movement. If the line slopes upward over time, it indicates an upward trend, and, if it slopes downward, the opposite is true.
