How the One Piece TCG Investment Index works

  • Equal-weighted in euros. Each index is calculated as if you invest €1 in every constituent (equal weight). Daily moves reflect the average relative price change across the basket.
  • Relative price movement over time. Each index starts at 100. A new value is calculated every day from the underlying products.
  • Indexes are baskets. Each index groups a specific category of One Piece TCG items. Manga Rare Index = manga rares only. Complete Index = all tracked products.
  • Quarterly rebalancing. Indexes are rebalanced every quarter to add newly released items and reset equal weights.
  • Compare categories. Use the indexes to see what leads and what lags: manga, SP, leaders, sealed, and more.
