A thought occurred to me the other day as I was looking at the filings page on the IndexUniverse weekly ETF Watch. It might be interesting to create a portfolio from some of the funds that are in registration. To be clear these funds do no exist (yet) and many of the filings are so old that it is quite clear to me that, assuming they are still active filings, some of the funds will never list but I'd very probably be a buyer of the WisdomTree Chilean Peso ETF if it ever listed. For purposes of this post I won't speculate on the likelihood that any filing will become a fund.
