A daily PSA 10 research letter
One graded card a day.
Every number shown.
Vault 10 Capital runs a fixed quantitative screen across PSA population data and eBay sold comps, then adds exactly one PSA 10 card per day to a public hypothetical portfolio at the median of its recent verified sold prices. No hype, no vague calls — the filters are published, the entries are timestamped, and the losses stay on the page.
Hypothetical model portfolio. Not financial advice.
The screen
Every gate a card has to clear
Real population
A market, not an anecdote
Enough PSA 10s exist that the quoted price reflects genuine trading.
Low gem rate
Structurally scarce
Hard-to-grade cards keep the PSA 10 float small however many are submitted.
Trading depth
Consistent recorded sales
A card that trades a few times a year has a price on paper only.
Settled grading wave
Past the rush
We wait for the release excitement to fade so an honest gem rate can emerge.
Closing float
Population growth, not level
A card whose PSA 10 supply is actively expanding is rejected however scarce it looks.
Durable subject
Characters that hold bids
Blue-chip Pokémon and named trainers find a bid in every downturn. Mid-tier ones do not.
Scarce printing
Bespoke art over base run
Alt arts and illustration rares carry the durable floor; the base run ranks last.
Patient entry
Near its own floor
We add chase cards that have drifted down, never ones mid-run.
Anchor intelligence layer
On top of the filters, Vault 10 Capital watches the anchor cards of each set — Pikachu and the other highly visible chase cards. When an anchor spikes sharply on confirmed sales, the engine scans the rest of that set for popular cards that have not repriced proportionally and prioritises the biggest remaining gap. If 1st Edition Jungle Snorlax runs, Jungle Pikachu and Eevee get looked at first — but only if they still clear every quantitative filter on their own.
