01Define the market
Spot metal, futures, equities and collectible auctions measure different things. Select the reference that actually relates to the decision.
- Identify instrument, venue and currency
- Note whether data is live or delayed
- Separate wholesale benchmarks from retail offers
02Establish comparability
Useful comparables share the attributes buyers care about. Similar-looking objects may differ in grade, certification, provenance or liquidity.
- Match specifications before price
- Adjust for transaction date and venue
- Exclude incomparable outliers
03Read the spread
The difference between bids and asks reflects liquidity, transaction costs and risk. A narrow spread often indicates a deeper, more standardized market.
- Ask which side of the market is quoted
- Compare multiple credible counterparties
- Include fees, shipping and payment costs
04Build a decision range
A defensible conclusion is often a range supported by multiple observations—not false precision from one number.
- Weight recent and relevant evidence
- State assumptions explicitly
- Update the range when conditions change
