Direct Answer
The COLEQTY is a rule-based measurement of Colombian equity market benchmark index tracking the Bolsa de Valores de Colombia, maintained by BVC/MSCI. Like every index it owns nothing: it is a number produced by applying a published weighting formula to a selected list of companies, revised on a schedule the provider sets.
What this index covers
The COLEQTY covers Colombian equity market benchmark index tracking the Bolsa de Valores de Colombia, within the Colombia market. BVC/MSCI defines which securities are eligible, how they are selected from that pool, and how much each one contributes to the published number.
The index name does not state a fixed company count, so the number of constituents follows the eligibility rules rather than a target.
How constituents are weighted
Each share's participation in the basket is determined by its adjusted market capitalization (capitalizacion bursatil ajustada), so larger companies carry more weight within the 40 shares.
The weighting method is the single biggest driver of how an index behaves. Two indexes covering the same market can diverge for years purely because they weight differently, which is why comparing index levels without knowing the method tells you very little.
What qualifies for inclusion
The basket holds 40 shares chosen by a selection function in which trading volume counts for 80%, trading frequency for 15% and turnover (rotacion) for 5%. COLEQTY also fixes the universe of selectable shares for any other BVC equity index that shares its selection method.
Eligibility rules are the part of an index most readers never look at and the part that decides what it can possibly measure. A screen that excludes a whole sector, or admits only one listing venue, shapes the result far more than any day of trading does.
The rule that surprises people
COLEQTY is the parent of a family rather than a standalone benchmark: BVC derives other equity indexes from its basket, for example COLSC, which takes the 15 COLEQTY shares with the lowest market capitalization.
