How positions resolve to the securities master. FIGI_COMPOSITE is exact identifier equality — both sides got the FIGI from Bloomberg. TICKER is a narrow fallback used only where the master row carries no FIGI at all (2,389 rows do not, disproportionately Irish-domiciled US listings like LIN and ACN). Roughly 22% of all positions resolve to the master.

Classification

classification.v_security_classification

Asset class: Equity
Sector: Utilities
Industry: Electric Utilities
Source: LLMunreviewed
Self-reported confidence: 0.95
Model: deepseek
Rationale: Oklo Inc. is a common stock in the electric services industry, classified under utilities.

Classifications are unreviewed model output. All 5,771 assignments carry source = LLM and is_reviewed = false. Confidence is the model’s own estimate and is not calibrated — it clustered at 0.90–0.98 across the whole first pass, including rows that later proved wrong. Use it to order a review queue, not as a probability. Two share classes of one issuer can disagree.

Not linked to a fund series.

Either this is not a fund, or it is one the SEC share-class snapshot cannot reach — commodity trusts and notes have no series ID at all.
