Portfolios

Rarebox supports multiple named portfolios, each with a color and their own value chart. The dashboard combines all portfolios into a single view showing total collection value, cost basis, and gain/loss.

Creating a Portfolio

Click the portfolio dropdown in the header and select New Portfolio. Give it a name and pick a color — the color appears in the dashboard charts so you can distinguish between portfolios at a glance.

Portfolio Items

Each item in a portfolio tracks:

• Card/product identity — name, set, image, type (card / sealed / graded)
• Cost basis — what you paid
• Quantity — how many you own
• Current market price — fetched live from pokemontcg.io or PriceCharting
• Gain/loss — absolute and percentage, calculated from cost basis vs. current price

Dashboard

The dashboard view shows:

• Total portfolio value across all portfolios
• Total cost basis
• Total gain/loss (absolute + percentage)
• Portfolio value-over-time chart (combined and per-portfolio)
• Individual portfolio breakdowns

Editing Items

Click any item in the portfolio table to edit quantity, cost basis, or to remove it. Changes persist immediately via debounced writes to IndexedDB.

Deleting a Portfolio

Deleting a portfolio removes all its items, associated snapshots, and price history data. This action is irreversible — export or backup first if you want to keep the data.

WARNING

Deleted items are cleaned up from snapshots automatically. The stale data cleanup runs on portfolio mutations to prevent orphaned snapshot entries from accumulating.
