Tracks the performance of lots against their estimate, indicating how many sold within, above or below this range, or remained unsold. This chart shows how the artist’s market performed compared to pre-sale expectations. For example, a rise in the proportion of unsold works may indicate that supply is outstripping demand and could lead to a future drop in prices.

Compares the proportion of lots sold across price ranges to the proportion of total value they generate. The chart shows whether an artist’s market over the last ten years has been driven by the sale of a small number of expensive works or a large number of inexpensive works.

Compare the artist's average sale price of their top works with the top 5 related artists.
