Some products may display seasonality – that is, predictable patterns which repeat themselves every year (for example, retail sales tend to be higher near nearer to the end of the year). In this model, an average of the product's value at each time of the year (averaged over multiple years) is shown, alongside the trend in a particular (usually the current) year. Furthermore, the maximum and minimum value for each time of the year are shown, to reveal any seasonal dependence in the product's volatility and/or estimate the significance of seasonal patterns.
