Um, they ain't in the 2000 or 3000 period. Just the MicroCap I'm afraid.
That isn't a huge deal. If you look at the largest Microcap ETF the iShares IWC has a NAV of $851m but would likely hold less than $200k of XXII at the current market cap.
TravelZoo TZOO has a cap of $140m and IWC only holds $185k of it.
Global Water Resources GWRS has a cap of $201m and IWC holds $200k of it.
XXII will likely fall within the two.
Out of the other microcap ETFs WMCR is the largest at $28m so the effect it will have on XXII buying is minimal.
