The PokéViews Graded Index by Era tracks PSA 10 graded Pokémon cards across four collecting eras using the following methodology: Baseline: All era indexes are set to 100 on January 1, 2022. Index values represent cumulative performance from this baseline (e.g., an index value of 264 means $100 invested at the start would be worth $264 today, a 164% return). Constituent Selection: The top 50 PSA 10 graded cards per era by market price are selected monthly (200 cards total across 4 eras). Cards must meet the following criteria: • Minimum sales volume threshold to ensure reliable pricing • Active trading: Price changed in the last 30 days or newly listed • Volatility filters to exclude extremely illiquid markets Eras Included: Vintage, Classic, Mid Era, and Modern. Contemporary Era Exclusion: Contemporary era PSA 10 cards are excluded due to insufficient price maturity and extreme volatility during initial grading periods. Contemporary exposure is available through the Sealed Index by Era. Individual sealed products, non-PSA graded cards, and non-English cards are excluded. Weighting Method: Equal-weighted within each era's top 50 cards. Rebalancing: Conducted monthly on the first day of each month. Smoothing: PCHIP (Piecewise Cubic Hermite) interpolation applied to generate smooth daily values between monthly rebalancing points and the current day. Calculation Frequency: Index levels are updated daily based on PriceCharting data.

Era Classification: 5 eras tracked: • Vintage: Original, Legendary Collection, Neo series • Classic: E-Card, EX series • Mid Era: Diamond & Pearl, Platinum, HeartGold & SoulSilver, Black & White series • Modern: XY, Sun & Moon series • Contemporary: Sword & Shield, Scarlet & Violet, Mega Evolution series.
