Price Tracking and Portfolio
Portfolio tracking = price + condition + provenance + sell signals. Card Ladder is the default; spreadsheet works for <50 cards.
Portfolio tools
- Card Ladder Pro ($25-50/mo): tracks portfolio, runs analytics, alerts on price moves
- Sportscard Pro: free portfolio tracker, basic alerts
- Goldin Vault: portfolio + consign-ready integration
- Custom spreadsheet: Google Sheets with eBay API for <50 cards
- CardPrepAI Portfolio (in development): empire-native tracker
Tracking essentials per card
- Acquisition cost
- Acquisition date
- Current grade + slab
- Recent comp (last 30 days)
- ROI % vs acquisition
- Sell-signal threshold (e.g., +50% from acquisition)
- Last verified pop count
- Notes (provenance, special story)
Sell-signal triggers
- Price > 100% above acquisition + good liquidity → sell candidate
- Pop growth > 20%/quarter → consider selling before compression
- Player retirement/scandal → liquidate quickly
- Set decade anniversary → time-window premium
- Trade window narrowing (e.g., MLB hot streak) → sell hot
