riser

A riser is something that moves upwards or increases over time.

When we talk about elevators, escalators, or stairs, we might refer to them as risers. For instance, if a building has 20 floors and each floor has a certain number of steps, those steps are the risers. It's also common in construction and engineering to use "riser" for pipes that carry water, electricity, or other substances upwards.

In finance, a riser can also be an upward trend or increase in something like stock prices or inflation rates. Think of it as something going up over time, whether it's physically moving higher or numbers increasing.
