ECON seeks to track an index of companies located in emerging market countries. The portfolio includes securities screened from its parent index, composed of large- and midcap securities with growth and value characteristics. Roughly 325 - 400 securities are selected through rules-based, strategic beta approach, which considers company quality, value, and catalyst factors. Weighting is based on free-float market-cap. Reconstitution is done semi-annually in May and November. Prior to Oct 19, 2016, the fund had a different name reflecting EGShares as issuer. Columbia acquired EGShares on Sep 1, 2016. Prior to Mar 18, 2019, ECON tracked a related index of 30 emerging-market consumer companies. Prior to Jun 28, 2024, the fund was named Columbia Emerging Markets Consumer ETF, and tracked the Dow Jones Emerging Markets Consumer Titans Index.
