How this report is made

Every number comes from daily TCGplayer market prices (near-mint, USD) stored by Tallgrass, as of the report day — nothing here uses data from after that date. The market index is chain-linked and value-weighted across every English card's regular printing, so new listings don't move it. Movers cover Scarlet & Violet and Mega Evolution cards worth at least $10 at both ends of the week that actually traded during it. Graded sales are eBay and Fanatics Collect sold listings.
