Cost data & sources

Confidence (level vs trend)

Example: the Cost Index is sure beef is climbing but won't pin the exact dollar — trend confidence is high, level confidence is medium, so the headline reads medium. You can act on the direction without trusting the cent.

level certainty vs trend certainty

Cost Data & Sources

Two separate certainties about a price: how sure you are of the dollar figure (level confidence) and how sure you are of which way it is moving (trend confidence). The two don't have to match — you can know prices are rising without knowing the exact dollar. The Cost Index scores both and shows the lower one as the headline.

Why it matters

Lumping the two together hides what you actually know. A well-measured price shouldn't be marked uncertain just because last week's direction was noisy, and a clean direction shouldn't imply a dollar you can't name. Splitting them lets you act on the half you trust — and the Cost Index headlines the lower of level and trend so the number never claims more certainty than its weaker half can hold.

Frequently asked

What's the difference between level confidence and trend confidence?

Level confidence is how sure you are of the dollar figure — the price right now. Trend confidence is how sure you are of which way it is moving — up, down, or flat. They are two different questions, so they get scored apart. You can be very sure of the direction while the exact dollar is fuzzy, and you can know an exact dollar today while the next move is anyone's guess.

Why does the headline confidence show the lower of the two?

Because a reading is only as trustworthy as its weakest half. If the dollar is well measured but the direction is noisy, calling the whole thing high-confidence would overstate it. Showing the lower of level and trend keeps the headline honest: it never promises more certainty than the shakier of the two parts can support.

What do the confidence labels mean on the Cost Index?

Level confidence runs high, medium, or no-dollar depending on how many independent dollar sources agree. Trend confidence runs high, medium, low, or directional depending on how cleanly the sources agree on direction. A jagged, noisy path is capped at low no matter how its endpoints line up, and a published label can never exceed what the source data supports.

Can you be confident in a trend but not the price?

Yes — that is exactly why the Cost Index scores them apart. You can be sure an ingredient is rising (high trend confidence) while the exact dollar stays fuzzy (medium or low level confidence), or know today's dollar without knowing the next move. The headline takes the lower of the two, so it never claims more certainty than the weaker half supports.

A price carries two different certainties, not one. The first: how sure you are of the dollar — the exact figure today. The second: how sure you are of the direction — whether it is heading up, down, or flat. They are two different questions, so they get scored apart.
The first is LEVEL: how sure you are of the dollar. It runs high when several independent sources agree on the same price. One source alone drops it to medium, and with no citable dollar it scores no level at all. It is a meter on the figure itself.
The second is TREND: how sure you are of the direction. It runs high when sources cleanly agree on which way it is moving. But a jagged, noisy path is capped at low no matter how the endpoints line up — noise is not a trend.
They can differ. You are sure of the direction while the exact dollar stays fuzzy — and the other way around too. The Cost Index is sure beef is climbing but will not pin the exact dollar: trend high, level medium. You can act on the direction without trusting the cent.
So the headline takes the LOWER of the two. Trend high, level medium: the headline reads medium. A reading is only as trustworthy as its weakest half, so the number never promises more certainty than its shakier side can hold.
