Convexity

Describing a curve segment whose ends fall above an arbitrarily set straight line. Convex properties are important to charting; for example, when tracking a stock market's performance, a rise in the chart with respect to the previous day's close followed by a correction going down to but not necessarily meeting that close may be described as a convex curve. See also: Concave.
