Forecast cards

Four numbers per horizon

01

Median forecast

The most likely price at that horizon and the change from now.

02

80% range

Built from the distribution of past errors, not a hand-drawn band.

03

Probability of a rise

The chance the price ends higher than now, for when direction is what matters.

04

Past error

How wrong forecasts at the same horizon were on average (MAPE).

Chart

Last year overlay and past forecasts

The 3-month, 1-year and 3-year chart overlays the actual price, the same day last year, the forecast median and the 80% range. Switch to “Past forecasts (backtest)” to see how earlier forecasts compared with what happened. Demand events such as Christmas are marked on the chart.

FAQ

Frequently asked questions

What are the horizons?

Daily items: 1 week, 2 weeks and 1 month. Monthly items (import prices, commodities): 1, 2 and 3 months.

How should I read a wide range?

It means past errors for that item and horizon were large. Then direction and the probability of a rise are more useful than the level.

Can I get a PDF?

Yes, PDF reports and CSV can be downloaded from the item screen (PDF from Pro).
