An AMR Index is a measure of market sentiment for a wide range of art, antiques and collectibles traded at auction since 1975. Auction sales data, being rich due to the number of transactions, offer an unbiased assessment of the value of artworks at the point of sale, as the hammer price exceeds the maximum willingness to pay of all bidders except (perhaps) the buyer.

Transactions on Art, Antiques and Collectibles are recorded from auction houses worldwide and updated to AMR’s database every month. Data analysts with specialist knowledge of art history, then categorises each individual lot into Painting (unique two-dimensional works), Sculpture, Photographs and Sculpture. For Antiques and Collectibles, we employ experts in each field to value a ‘basket of goods’ and update prices once or twice yearly.

Art Market Research’s indexes helps you work out how much a work of art or antique could be worth on the open market today. If you know how much an item cost in the past, AMR’s revaluation tool will help you confidently estimate current values.

You can find the revaluation tool on every chart, along with a table with individual indices used to drive the valuation including the number of auction lots.

Founder, Robin Duthy, a financial analyst in the City of London, published the first reference books on alternative investments. Alternative Investment (1978), followed by The Successful Investor (1986) were best-sellers in the UK and USA. In 1999, Duthy pioneered the first web application for his Art Market Indices and artmarketresearch.com was adopted by the UK Inland Revenue’s Shares and Asset Valuations department to be used in determining fair market value on non-wasting chattels. Duthy’s indexes have appeared regularly in the Financial Times, The Wall Street Journal, The Economist and many others.

Yes. AMR offers quarterly or annual subscriptions so clients have hassle-free access to the indexes they need.

You can print AMR’s indexes in PDF format or download the indices in CSV format. You can also download the component lists of the group indexes into an Excel sheet.

We can only create indexes for Artists whose works exchange hands regularly at auction. If you would like to know about an artist who doesn’t appear at auction very often, you may find him or her in one of the many group indexes we offer. If you still can’t find the artist you are looking for, we can offer advice on the formulation of a new group index.

AMR gathers only non-proprietary data published by auction houses. Private art dealers do not, on the whole, reveal final transaction prices and so private sales are not included in our data sets.
