MasterDATA is long experienced with updating, maintaining and utilizing constituent lists. Since 2001, MasterDATA has been compiling breadth data for its subscribers. Breadth data reflects what each constituent of an index or ETF is doing in combination with all other constituents of the same index or ETF. Accurate and rigorously up to date constituent lists are therefore essential in compiling accurate breadth data. Expanding on its experience in providing this data, MasterDATA now provides constituent lists on a majority of equity ETFs trading in the United States. Investors, fund managers and hedge managers use constituent lists for many purposes limited only by their imagination and objectives. MasterDATA formats the lists into one downloadable datafile (.csv format), easily implemented into an existing data structure.

Additionally available are constituent change reports reflecting both significant weighting changes and additions or deletions of constituent issues to the ETF. Weighting changes may occur when a particular issue experiences a major price change relative to other issues in the ETF. Weighting changes may also occur when the ETF manager adds additional shares or sells part or all of the ETF’s position in a particular constituent. The removal of a constituent from an ETF may occur for many reasons including an issue merger, bankruptcy, delisting, or performance outlook. Most ETFs will replace a removed constituent with a new constituent issue that meets the criteria of the ETF objectives. Certainly, while these may be the primary reason, there are many reasons why a constituent may be added or removed from an ETF. Using these very unique reports, investors will gain insight as to the current internal strategy of the ETF managers.

With ETFs one of the newest and fastest growing segments of the investment marketplace, the importance of accurate and up to date constituent lists is apparent.
