Advance/Decline Spread(redirected from Advance-Decline Indices)
In technical analysis, the total of stocks increasing on a trading day less the number of stocks declining on the same day. Technical analysts use the spread as an indicator of market breadth. A positive spread indicates that a trend is or will soon become bullish, while a negative spread shows a bearish trend.
