parabolic

Like satellite dishes

Parabolic describes something shaped like or relating to a parabola—the U-shaped curve formed when a cone is sliced parallel to its side.

A parabolic antenna or mirror uses this shape to focus signals or light at a single point.

In finance, parabolic describes prices rising at an accelerating, unsustainable rate: The stock went parabolic before crashing.

Parabolic can also mean relating to parables, though this sense is rare.
