Form N-Q for iShares Trust was filed 8/29 (late) for the period ended June 30, 2013:
65,279 iShares micro-cap ETF
436,045 iShares Russell 2000 ETF
190,547 iShares Russell 2000 Growth ETF
6,766 iShares Russell 3000 ETF
1,256 iShares Russell 3000 Growth ETF
other late filers include:
104,800 Fidelity Central Investment Portfolios LLC
23,404 Northern Funds
3,300 Fidelity Capital Trust
which means the total FMR ownership so far identified from various FMR funds is 4,329,358 (11.1% of outstanding shares) despite their recent "selling". BTW, the 104,800 in Fidelity Central Investment Porfolios (as of June 30, 2013) was not present in their previous N-Q for May 31, 2013 (they are constantly moving stuff around, to give the impression of selling??) ...and tracking who shorts what and when is impossible.
Anyway, total insti ownership (excluding the 1M+ shares in Insmed BOD/mgt hands) is now 23,138,223 (59.3% of outstanding shares)
or 24,312,460 (62.5%) including Insmed BOD/mgt holding (and mine).
