Price Position

Where the current price sits relative to its own history

Price Position shows where the current price sits compared to the product's own price history. It tells you whether the product is priced unusually high, low, or normally relative to its typical range.

What It Measures

This metric compares today's price to the full distribution of historical prices for the same product. It calculates what percentage of historical prices were lower than the current price (the percentile) and how far the current price is from the historical average.

Promotional spikes are excluded from the historical distribution so they do not skew the comparison.

Why It Matters for Resellers

Knowing where the current price falls in the product's history helps you:

  • Spot buying opportunities. A price well below average might be temporary, meaning you can source at a low cost and sell when the price reverts.
  • Avoid buying at peaks. A price well above average is likely to fall back, which would erode your margins.
  • Assess margin sustainability. If the current price is near its historical average, your margin calculations are more likely to hold.

How We Calculate It

  1. We collect the product's complete price history, excluding promotional spikes.
  2. We weight each historical price by how long the product was at that price (duration-weighted).
  3. We calculate where the current price falls in this weighted distribution.
  4. We measure the distance between the current price and the product's historical floor (lowest recorded price).
  5. We count how many times the price has touched or come very close to the floor (within 5%), which indicates a price support level.

How to Read the Results

| Classification | What It Means | |---------------|---------------| | Well below average | The price is far below its historical average. This could be a buying opportunity if demand is still healthy, or a sign of increased competition. | | Below average | The price is lower than usual. It may revert upward, which would improve your margins if you source now. | | Near average | The price is near its historical average. No unusual pricing pressure in either direction. | | Above average | The price is higher than usual. Margins look good now, but the price may come back down over time. | | Well above average | The price is far above its historical average. This is likely temporary — expect it to fall back toward normal levels. |

Prices well below or well above average tend to move back toward the middle over time. This matters when deciding if current margins are sustainable.

Limitations & Caveats

  • Mean reversion is a tendency, not a guarantee. Prices can stay at unusual levels for extended periods, especially if market conditions have fundamentally changed.
  • Historical distribution may not reflect current market. If the product's competitive landscape has changed (new competitors, brand gating, etc.), past prices may not be a good baseline.
  • The "floor" is the lowest observed price, which may have been an anomaly rather than a true support level. More support touches give you more confidence the floor is real.
  • Very short price histories produce less reliable position readings. A few weeks of data creates a narrow distribution where small price changes look significant.
