I just went back and spent the extra 5 minutes to pull some historical snapshots of Van Ecks holdings. Using the annual and semiannual reports on their website, plus an SEC filing in November of '12, here are the numbers
12/31/11
GDX 21,484,506
GDXJ 23,104,352
6/30/12
GDX 25,277,991
GDXJ 36,647,321
10/31/12
GDX 25,409,028
GDXJ 42,837,927
I still say they can't really keep GBG in there just for charter compliance - but that's my opinion only. What's intriguing to me is that GDXJ chased this pretty hard all during '12 - that speaks to Van Eck seeing these assets as being extremely undervalued at much much higher prices. Sucks to be them and have to sell them now.
