Investment Grade

Investment Grade (S to F)

This is a durability score: how robust a card's demand is, separate from what it costs today. It blends how badly people want the card (its total graded population plus PSA-10 value), the character's pull, how steady the price has been, how liquid it is, how settled the set is, and whether it's a collector chase or a playable.

• S the very top: marquee grails with the deepest, most durable demand.
• A / B blue-chip demand, the kind you hold for the long run.
• C middling fundamentals.
• D / F fragile demand, so hold with care.

Gaining steam & vs fair

Gaining steam just tells you a card's price is up over the last 30 days or so. It's a read on what already happened, not a bet that it keeps going. (Rising grading demand will join this once we've banked a few monthly population snapshots.) The little vs fair chip shows where the price sits against our fair-value model, so you can see if you'd be overpaying to get in. It is not a signal to sell.

We won't tell you a card will go up. Our backtests never found a reliable way to call that, so this board sticks to what we can stand behind: durability, and what's moving right now.
