Cyclical variation
Economic expansions and contractions can influence demand over periods that vary in length and intensity. Unlike a seasonal pattern tied to a fixed period such as a quarter or month, cycles do not necessarily repeat on a fixed schedule. Separate them carefully from trend and irregular shocks where possible.
Worked example
A business’s sales weaken during a multi-year economic downturn and recover during expansion. The movement may be cyclical; a regular December peak is seasonal.
Common mistake
Classifying an annual holiday peak as a cyclical movement simply because it repeats.
