Fell most over the month

Rose most over the month

Every category

Categories with fewer than 8 models on the last day are left out, because one listing would swing them. Each figure is that category's own chained index over the month.

16 categories marked mostly on moved most of the month in one or two days. A category index moves 2% in a day only about once in eighty days, and when it does it is more often the collector matching different listings than a change in what things sell for, so those are left out of the lists above.

How to read this

It is a cheapest-listing index, so it tracks where the floor of the secondhand market sits rather than what a typical buyer pays. It is chained day to day, and a single-day move on one model of more than 25% up or 20% down is discarded as the collector matching a different listing rather than a price change. The full method is on the daily index page.

This page is written once, when the month ends, and is not revised afterwards. The daily figures behind it are in the CSV, and the copy on GitHub has a commit for every day, so any number here can be checked against the day it was recorded.
