Vanguard continues making it difficult, and often impossible, to obtain current constituent lists for their ETFs. .In the worst cases, they recently stopped supplying a current list at all.  At the present time, Vanguard's ETFs are all index based.  In an effort to meet the needs of investors using composite breadth data, MasterDATA will begin using the index constituent list rather the constituent list for the Vanguard ETF itself.  Generally, the lists are very similar, if not identical.  This change in source data for their constituent lists will be implemented over the next few weeks.

Editorial Note:  Vanguard is the only ETF sponsor that refuses to provide current constituent lists to investors.  The effect is to make the playing field biased in favor of certain large investor types (willing to pay for the lists) at the expense of the majority of investors.  In today's world, this is simply wrong.  More than ever, the playing field must be level.  If you agree, please let Vanguard know your opinion, by clicking here.

ProShares, Direxion and some Rydex ETFs are a "leveraged" and/or "reciprocal" version of several widely followed stock indexes such as the Dow Jones Industrial Average, S & P 500 Index, NASDAQ 100 Index and Russell 2000 Index.  Their structure often requires the use of futures contracts and / or Swaps, neither of which qualify under MasterDATA's qualification criteria.  Performance of the ProShares, however, generally achieves their stated objective and makes these ETFs very attractive to investors and traders capable of incurring the higher risk in these funds.  For that reason, we include ProShares qualifying as ranked by trading volume.  composite breadth data for the underlying index is included in the historical datafiles for these ETFs along with the actual trade prices and volume of the ProShares or Rydex ETF itself.
