Plus Tick

See: Zero Plus Tick.

A medicine your dog has to take? The name you get when a lazy Ellis Island employee meets Greek immigrant Plustokis Tickeroglou?

Nope. It's the name given to a momentary upward move by a security.

Stock prices bounce around moment to moment. Up a little now, down a little a bit later. These tiny moves can add up to large moves over the course of a day or a week or a year or whatever. But the smallest unit of a security's movement is known as a "tick." In the same way that a stroll is made up of individual steps, a stock market advance or decline is made up of a series of individual ticks.

A plus tick represents a move higher (as opposed to a minus tick, which has the stock edging lower in that moment).
