Reading an Auction House's Annual Results

⁰¹Most major auction houses announce their sales results each year, and many publish half-year figures too. Reading an auction house's annual results well starts with knowing what kind of document it is: a communications release summarising the house's activity, not a set of audited accounts.

⁰²Several of the largest houses are privately held, and their sales announcements are not the same thing as financial statements. Where a house or its parent company is listed, or files accounts with a companies registry, those filings are a more rigorous source, though usually less timely and less detailed about sales.

⁰³A release is accurate on its own terms. The point is that the terms are chosen by the house, and they are chosen to present the year well.

⁰⁴Timing matters as well. Half-year and full-year figures are shaped by the auction calendar, and the major spring and autumn sales fall in different halves of the year, so comparing one half with the other says little. The fair comparison is the same period in the previous year.

⁰¹The headline figure is typically the total value of works sold, and it is usually premium-inclusive: hammer prices plus buyer's premium. Depending on the house and the year, it may combine several kinds of activity.

⁰²Each of these is legitimate. The difficulty is that the combination can change from year to year and from house to house, and a release may not spell out the change prominently.

⁰¹A sales total measures what passed through the house, not what the house earned. The house's revenue comes from buyer's premium, seller's commission and fees, and its profit depends on costs, including marketing, staff, guarantees and financing. None of that is visible from the headline number.

⁰²Guarantees are a particular blind spot. A total that includes guaranteed lots counts those sales at full value, whether they sold to competing bidders or to the guarantor at a pre-agreed level, and it says nothing about losses the house may have absorbed when a guaranteed work sold below its guarantee.

⁰³Unsold works are also largely absent. Some releases give sell-through rates, which help; others do not. Sales that fail to complete after the auction, for example because a buyer does not pay, may or may not be reflected in later figures.

⁰⁴Changes to the house's own premium schedule also flow into the total. If the buyer's premium rises, the same hammer prices produce a higher premium-inclusive figure, so part of any reported growth can come from pricing rather than from demand.

⁰¹Private sales brokered by auction houses have been widely reported as a more prominent part of the major houses' business, and many now report them alongside or within their auction totals.

⁰²They are the least verifiable part of the figure. Private sale prices and parties are not disclosed, so the reader depends entirely on the house's own accounting and definitions. A rising private-sales figure may reflect genuine demand, a shift of activity from the auction room to private channels, or a broader definition of what counts. Without more disclosure, a reader cannot tell which.

⁰³Some houses also run activities that sit between auction and dealing, such as fixed-price online sales or selling works the house itself owns. Where these are included, the total is broader than auction in the ordinary sense, and the release may not break them out.

⁰¹A few steps turn a headline into something more useful.

⁰²Concentration deserves particular attention. A year with one or two exceptional single-owner collections can lift a total sharply without any change in the breadth of demand, and the following year can look weak simply because nothing comparable was consigned.

⁰³Growth rates need their base year. A strong increase following a weak year may simply mark a return to earlier levels, and a decline following an exceptional year may still leave the business larger than it was before.

⁰⁴Comparisons between houses are harder still. Each defines its figures in its own way, so a ranking built from their releases compares different measurements. The site's piece on industry-wide totals covers how figures like these feed into market-level estimates.

⁰¹Read carefully, a house's annual results still carry information. Over several years, and allowing for changes in definitions, they show the direction of the house's own business, which categories and salerooms are growing, and how much weight it places on private and online sales. Releases sometimes describe buyers too, such as how many are new to the house or where bidders are based, which is useful context when read as the house's own framing.

⁰²What they cannot show on their own is the state of the art market as a whole, the house's profitability or the strength of demand for any particular artist. The total is a signal about one business, presented by that business. Treating it as more than that is where misreadings start.
