The transition point between economic recession and recovery.

Trough

In a recession, the point of the most negative GDP growth that immediately precedes the beginning of recovery. In other words, it is the lowest point in a business cycle. The term comes from charting, in which the x-axis represents time and the y-axis represents GDP growth. In this situation, the low point of a business cycle looks like a trough or pit. A trough is also called a valley. See also: Peak.
