convexity

Noun

This term describes a physical or mathematical outward curvature. In optics and geometry, it evokes the image of a dome or a bulging surface, contrasting with the inward dip of concavity. It is used in technical contexts to describe how light bends or how shapes are structured. In specialized fields like finance, the word shifts from a visual description to a measure of sensitivity. It describes the rate of change in a bond's duration, acting as a risk management metric rather than a physical shape.
