Data Sources
We don't rely on gut feel or social media hype. Every recommendation is grounded in verifiable data from primary sources:
- Population reports — PSA Pop Report and SGC Population data for supply analysis on key cards
- Market comps — eBay sold listings (90-day rolling window) for real transaction prices, not asking prices
- Grading fee schedules — Direct from PSA, SGC, BGS, and CGC, updated within 48 hours of any price change
- Sportsbook odds — DraftKings, FanDuel, and BetMGM futures for Heisman, MVP, and championship markets
- Scouting databases — ESPN recruiting rankings, MLB Pipeline, Transfermarkt for player evaluation data
- Company filings & press releases — Collectors Holdings, Fanatics, eBay marketplace data when available
Valuation Framework
We treat every card recommendation as an investment thesis with a defined cost basis, catalyst timeline, and exit strategy.
All-In Cost Basis
The sticker price of a card is not your cost basis. We calculate the true all-in cost including:
- Card acquisition price (raw or graded)
- Grading fees at the selected service tier
- Shipping and insurance (both directions for grading submissions)
- Membership fees (e.g., PSA Collectors Club) amortized per card
- Supplies (top loaders, sleeves, submission materials)
Scenario Modeling
For each recommendation, we model three scenarios:
- Bull case — Key catalysts hit (e.g., player wins award, team advances, card pops stay low). What does the upside look like?
- Base case — Player performs as expected, market follows historical patterns. What's the realistic return?
- Bear case — Injury, underperformance, or market correction. What's the downside risk and can you recover your cost basis?
Time Horizons
- Short-term (1–3 months) — Trading around specific catalysts: draft night, roster announcements, tournament performances
- Medium-term (6–12 months) — Season-long holds targeting breakout performance or award races
- Long-term (2+ years) — Career trajectory plays on generational talents
Conviction Ratings
Every player or card recommendation gets assigned a conviction tier:
- Core Hold — High conviction, moderate risk. These are the blue-chip positions we'd allocate 40–60% of a themed portfolio to.
- Speculative Buy — High upside, high risk. Small positions (5–15% of portfolio) with asymmetric return potential.
- Trim / Sell — Take profits or exit. The risk/reward no longer favors holding.
Portfolio Construction
We apply a venture capital framework to card portfolio construction. Just as a VC fund diversifies across stages (seed, Series A, growth), we recommend diversifying across:
- Conviction tiers — Mix of core holds and speculative plays
- Sports — NFL, NBA, MLB, soccer to reduce single-sport concentration risk
- Time horizons — Near-term catalyst plays alongside long-term holds
- Grading status — Raw cards for speculation, graded cards for long-term positions
What We Don't Do
- We don't accept payment for coverage or placement
- We don't pump cards we're selling
- We don't recommend cards without running the cost-basis math
- We don't use anonymous sources — all data is verifiable from public sources
