FOR APPRAISERS & ADVISERS

AMR reads the auction record so you don’t have to assemble it — and gives you a rule-based benchmark you can reach quickly, cite, and put your name to. It sets the value on shared, transparent ground; it doesn’t replace your judgement.

WORKS WITH YOU, NOT INSTEAD OF YOU

A benchmark for your judgement.

The Trendline is, by design, a durable, long-run read— a rule-based benchmark of where an artist’s market has travelled, not a precise verdict on a single work. It gives everyone a shared, transparent figure to work from.

And it is not built to replace you. It takes on the part that is slow and contestable — assembling the market record, reading the level by rule, showing the working — so your time goes where only you can take it: condition, attribution, provenance, taste, the merits of the particular work.

WHY CITE AMR

It stands on the record, not on you.

A figure you assemble by hand rests on your standing to defend it. An AMR figure is read by rule from the published record — the method the same for every artist, the data open to inspection — so its authority comes from the record, not from you. Whatever the figure is for, that is a steadier place to start.

WHAT IT GIVES YOU

Defensible, faster, and ready to cite.

DEFENSIBLE

Read by rule, not by hand.

The figure comes off the published Central 80% record by a fixed method — the same for every artist, the data open to inspection. There is no line drawn to suit the case, and nothing anyone can call selective.

FASTER

The market evidence, already assembled.

You don't build the comparables set, convert the currencies, or strip the premium by hand. The record is read for you, dated and sourced — so your time goes on judgement, not assembly.

CITABLE

The defence is already written.

Every assessment carries wording built to be reproduced in a submission: the method named, the threshold disclosed, the figure and its band stated. You cite it; you don't draft it.

WHEN THE RECORD CAN’T CARRY IT

And when a figure won’t carry, the tool says so.

Where the record sits too far off its durable trend to read straight, the tool holds the figure back rather than force one — itself a defensible position. When you need a figure through that, an AMR specialist reads what the line can’t, in a commissioned Expert Read.

LANGUAGE FOR SUBMISSIONS

Wording you can lift straight into a report.

Each assessment is written to be reproduced verbatim or in substance. One framing for a value carried between two dates, one for where the record sits off its durable trend, one for no measurable change, one for insufficient coverage — so whatever the record supports, you have the language ready.

A clean read — value carried between two dates
The valuation has been derived using the AMR Trendline methodology. The change between acquisition and valuation date is read from the durable Trendline fitted to the artist’s published Central 80% Index, and the raw record tracks that trend across the window — the move is broad-based rather than an artefact of short-run supply or sentiment. The implied current value is [£X].
A heads-up — the record sits off its trend
At one of the chosen dates the artist’s Central 80% Index sits materially off its durable Trendline, indicating a supply- or sentiment-driven move rather than a broad shift in value. The durable Trendline change and per-year rate stand; under the AMR Trendline methodology the carried figure is held pending corroboration; named, dated comparable auction results near the subject value are provided to ground professional judgement, and a reweighted Expert Read is available where a single figure is required.
No measurable change
Under the AMR Trendline methodology, the artist’s published index and its durable trend show no movement between [YEAR] and [YEAR] that can be relied upon over the period. This is reported as a finding in its own right: the available auction evidence does not support a change in value over the period.
Withheld — insufficient coverage
The available auction-market evidence is insufficient to support a defensible trend-based valuation under the AMR Trendline methodology. Comparable auction results for the artist are provided for reference and to ground further professional judgement.
