Pi-eX's latest 12 month rolling report issued end of May 2020 shows that combined revenue at Christie's, Sotheby's and Phillips public auctions over the past 12 months was 41% less than the revenue achieved over the same period a year before (from over $11 billion to about $6.5 billion).  

This shows the major impact of the coronavirus pandemic on auction sales, especially over the months of April and May 2020 when monthly sales decreased by more than 90%.

Pi-eX 12 months rolling reports are similar to yearly reports as they cover a full year period but rather than starting on January 1st and ending on December 31st, they cover a rolling 12 month period as of the end of a selected month.
