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.

This match is a candidate, not a mapping. N-PORT tickers are filer-entered free text and collide with delisted and foreign symbols. Only 13% of positions carry a ticker at all. Good enough to ask which funds report holding a symbol; not good enough to build exposure reporting on. Prefer the ISIN-resolved link, which is marked FIGI_COMPOSITE.

Classification

classification.v_security_classification

Asset class: Equity
Sector: Information Technology
Industry: Semiconductors
Source: LLMunreviewed
Self-reported confidence: 0.95
Model: deepseek
Rationale: Alpha and Omega Semiconductor is a semiconductor manufacturer, classified under technology and semiconductors.

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.
