The weekly auction reports, introduced a year ago, have been revised. Members who have signed up for the free weekly reports will see a revised report when they receive the next issue on Sunday evening. Casual observers can see the same reports in the Upcoming Auctions section of AE by selecting Recent Weekly Auction Reports. New reports are emailed Sunday evenings at 9:00 pm PST and posted in the Upcoming Auctions section at the same time. A link to sign-up is provided at the end of this article.

The revised report, for those who look into the details of specific auctions by selecting Click Here to View Top Ten Lots by Sale Price, will find four new fields highlighted in yellow in the auction summary that provide detailed information about overall performance. Buyers logically focus on specific lots but all items offered are also part of specific events and their overall performance varies widely from house to house, from event to event. Deconstructing results provides evidence of the current market as well as clues to how each auction approaches their business. These new fields provide more information about these differences.

Under the umbrella of 'auction' - variation between houses is the norm, but houses tend to be internally consistent even as they adjust to changing circumstances - so understanding how they did provides evidence about how they'll do. In many cases the past is proscriptive. About this you'll have your own opinion. In recognizing the changes that houses make you'll gain insight into how they view the market. Because auctions provide a steady drumbeat of sales there's a close to real time continuum of data that provides the best evidence available about the current state of the market. But you do have to sort it out yourself because the book business is a braided tapestry, 19th century fiction a world apart from 18th century science, 20th century poetry several time zones away from early travel and voyages.

In issuing weekly reports we have for the past year focused on success rates, that is the lots sold. The market is recovered sufficiently that we can more clearly identify the proportion of lots unsold and add an important statistic: total sales as a % of high estimate. This is a telling number. Houses that accept or themselves impose reserves above current market value will tend to have a lower percentage of lots sold and also achieve a lower percentage of total receipts as measured by Total Sales as a % of High Estimate. If reserves are high fewer lots will sell and overall performance, as measured by total sales divided by the total high estimate, be lower. It may sound complicated but it reduces itself to a simple number.

A sale and the market will appear to be in balance when an auction achieves 100% of the high estimate. In a rising market that percentage will tend to be above 100%, in a declining market below. This said, these statistics can only be applied to auctions as a group. Specific sales will often be subject to random events that increase or decrease revenue. But taken together, these numbers provide a riveting picture of a selling channel constantly in flux, adjusting to changing demand.

Momentum, the rate of change and its implication for future pricing, is the subject of our ongoing study.
