Indeksai

Indeksai is the plural form of indeksas, a term used in Lithuanian and other languages to denote an index or indicator. In broad use, indeksai refers to a reference point, a composite measure, or a system for organizing information.

In finance, financial indices track the performance of a basket of securities. They serve as benchmarks and are used to measure market performance, compare funds, and to create passive investment products. Construction typically involves selecting constituents, assigning weights, and calculating a weighted average of prices or capitalization, often with a base value.

In statistics and related fields, an index is a composite indicator representing a concept through multiple measures. Examples include economic, social, or development indices. Construction involves indicator selection, normalization, and aggregation; weighting influences the final score and interpretation.

In information science and computing, indeksai include indexing systems that enable efficient data retrieval. In libraries, catalog indexes assist in locating records; in databases, database indexes accelerate queries by mapping values to storage locations. In web search, indexing collects and organizes pages to support fast and relevant query results.

Etymology and usage: the term derives from Latin index, meaning indicator. In Lithuanian, indeksai is widely used across fields, though some disciplines prefer English loanwords for precision.
