AssetType

Overview

AssetType provides granular classification of a financial instrument within a broader asset class, such as distinguishing stocks, convertibles, warrants, and preferred stocks within equities, or U.S. Treasuries, Corporate High Yield, and Municipals within fixed income. It works alongside AssetClass and SecurityType to form a complete taxonomy for securities and research focus areas, and supports publisher-defined extensions when the standard enumeration is insufficient (sources: data-dictionary-2.4 p.53, data-dictionary-2.5.1 p.56, user-guide-2.3.1 p.39).

Usage

AssetType appears most commonly as a child of Security (within SecurityDetails), where it is required exactly once, and may also be used inside Context / ProductClassifications to classify the research focus itself (sources: data-dictionary-2.4 p.53, user-guide-2.2 p.38). The required assetType attribute carries a value from AssetTypeEnum (e.g. Stock, Convertible, USTreasuries, CorporateHighYield). The optional publisherDefinedValue is used together with the enum value PublisherDefined to convey a custom type, and the optional weightingAction tracks publisher changes to the asset-type weighting [RIXML User Guide v2.2 p.38]. In full-schema usage the element may carry Rating and Weighting children to express ratings or weightings scoped to the asset type. In RIXML Level One the element is reduced to a pure container for the assetType attribute and these children are not used (sources: level-one-2.2 p.20, level-one-2.5 p.15). Typical pattern: - Pair AssetClass (broad bucket, e.g. Equity) with AssetType (narrower bucket, e.g. Stock) and optionally SecurityType for instrument-level detail. - For specialised fixed-income research, AssetType is the key discriminator driving credit, duration, and sector workflows [RIXML Research Data Dictionary v2.5.1 p.56].

Rules

• MUSTEach Security element must contain exactly one AssetType child carrying a required assetType attribute valued from AssetTypeEnum.[RIXML Level One Addendum v2.2 p.21] [RIXML Level One Addendum v2.3 p.15] [RIXML Level One Addendum v2.3.1 p.15] [RIXML Level One Addendum v2.5 p.15] [RIXML Research Data Dictionary v2.5.1 p.56]
• MUSTWhen assetType is set to PublisherDefined, the publisherDefinedValue attribute must be populated with a description of the custom asset type.[RIXML User Guide v2.2 p.38] [RIXML Research Data Dictionary v2.5.1 p.56]
• SHOULDWhen classifying securities, both AssetClass and AssetType should be provided to form a complete hierarchical classification (e.g. Equity / Stock).[Company Report (Basic) Sample v2.4]↗ [Industry Report (Basic) Sample v2.4]↗ [Morning Call Report (Basic) Sample v2.4]↗ [RIXML Level One Addendum v2.3.1 p.15]
• INFORMATIVEUnder RIXML Level One, Rating and Weighting are not required as children of AssetType; the element functions as a pure container for the assetType attribute.[RIXML Level One Addendum v2.2 p.20] [RIXML Level One Addendum v2.3 p.15] [RIXML Level One Addendum v2.3.1 p.15] [RIXML Level One Addendum v2.5 p.15]
• INFORMATIVEUnder RIXML Level One, AssetType as a child of ProductClassifications is not required, since asset-type information is conveyed at the security level.[RIXML Level One Addendum v2.3.1 p.18]

Relationships

• child-ofSecurity — AssetType is a required single child of Security within SecurityDetails, specifying the granular instrument type for the security.
• narrowsAssetClass — AssetType narrows the broad bucket given by AssetClass (e.g. Equity → Stock, FixedIncome → USTreasuries).
• qualifiesSecurityType — AssetType works in conjunction with SecurityType to provide a complete instrument taxonomy, sitting between asset class and security-type detail.
• uses-enumAssetTypeEnum — The assetType attribute draws its value from AssetTypeEnum, including the PublisherDefined extension point.
• may-containRating — AssetType may contain Rating child elements to express a rating scoped to the asset type (outside Level One).
• may-containWeighting — AssetType may contain Weighting child elements and an weightingAction attribute to express weighting and weighting changes at the asset-type level (outside Level One).
• child-ofContext — AssetType may also appear inside Context / ProductClassifications to classify the research itself rather than a specific security.
• replaced-byAssetClass — RIXML v3.0 drafts propose consolidating AssetClass, AssetType and SecurityType into a single hierarchical asset-class tag set analogous to the sector/industry taxonomy.
