Indexwerts

Indexwerts is a term used in finance to denote the numerical value of an index at a given moment. In standard German, the corresponding noun is Indexwert, with the plural Indexwerte; "Indexwerts" may appear as an anglicized or nonstandard form in some texts. An index value summarizes the performance of a predefined basket of assets or indicators into a single number, providing a compact reference point for market movement.

Indexwerts are calculated according to a predefined methodology. Common approaches include price-weighted indices, where component prices determine weights; value-weighted (market-cap weighted) indices, where component market capitalizations determine weights; and equal-weighted indices, where all components contribute equally. A base value and base date establish the starting point, after which movements reflect relative changes. Periodic rebalancing can adjust components or weights to reflect strategy or maintain exposure targets.

Indexwerte are widely used as benchmarks for portfolio performance, as underlying references for derivatives, and as indicators of market conditions or economic trends. They are sensitive to corporate actions such as stock splits or dividends and may require methodological adjustments to maintain continuity. Limitations include that an index does not measure total market value or wealth and that its interpretation depends on the chosen components and weighting scheme. Examples of widely followed indices include stock, bond, and commodity indices used by investors and researchers to gauge relative performance and risk.
