Math Class: Sneakerhead Statistics Defined

These are the seven main statistics that we use throughout our work.  As we add more stats and terms we will update this list.

  1. Average Deadstock Price:  The average sales price of all deadstock, mens sneakers sold on eBay over the past 12 months.  We’ve removed fakes, outliers and auctions with multiple pairs.
  2. Total Sold:  The total number of mens sneakers sold on eBay over the past 12 months (deadstock and used).  We’ve removed fakes, outliers and auctions with multiple pairs.
  3. Price Volatility:  A measure of how much we can expect deadstock price to fluctuate – it provides an average price range.  A sneaker with an average DS price of $200 and a Price Volatility of 40% means that we can expect the price to be between $120 and $280.  Price Volatility is calculated as standard deviation divided by average price.
  4. Resell Price Premium:  A measure of how much more a sneaker sells for in the aftermarket, as compared to its retail price.  A sneaker which retailed at $150 and now has an average price of $300 on eBay would have a Resell Price Premium of 100%.  This is also known as “margin” or “markup”.
  5. Deadstock Price Premium:  A measure of how much more a deadstock sneaker sells for, as compared to a used pair.  A sneaker with a DS Price Premium of 100% means that the average price of a DS pair sells for twice as much as a used pair.
  6. Deadstock %:  The percentage of deadstock pairs on eBay – as opposed to used.   A Deadstock % of 60% means that 60% of all mens sneakers on eBay are DS, and 40% are used.
  7. Sold %:  The percentage of eBay auctions which ended in a sale – as opposed to those which ended with no sale.  This provides a snapshot of market availability:  the higher the Sold %, the fewer pairs sitting on virtual shelves.
