Investment Gains Tracker
Tracks market gains vs contributions for ISA and GIA. Source: Home Assistant Trading 212 sensors (daily pull). SIPP excluded — no HA sensors for Freetrade/T212 SIPP.
Baseline: 26 Aug 2026
Pre-June history (backfilled 17 Sep 2026): finance/investment-history.csv
now reaches back to 15 Jan 2026. Rows before 29 Jun 2026 come from the
Trading 212 activity-statement PDFs in Joe’s email archive — HA’s sensors did
not exist before 29 Jun, so this is the only record of that period. Two caveats:
they are activity-day snapshots, not a continuous series (the gaps between
them are real, not missing data), and pre-June rows carry no position detail, so
the YCA block correctly ignores them. “Invest” in the statements = today’s GIA.

Yellow Cake (YCA) — the one non-index holding
Jersey-incorporated holder of physical uranium (U3O8). Held in both the ISA and the GIA. Tracked because it is the only concentrated, single-commodity position in the book: no earnings, no dividend, no compounding engine — it can fall and stay down in a way a diversified index cannot.
Full daily log: finance/investment-history.csv — 88 days recorded, source of truth. HA retains only ~5 weeks of position history,
so the CSV, not Home Assistant, is the record.

- GIA holding: £2,695 = 18.0% of the GIA (exact — the GIA holds exactly two positions)
- ISA holding sits inside the 20.4% non-Invesco sleeve; the integration exposes no per-position value, so its exact size is not observable
