As I noted in a reply to another post, Google Finance is missing August 2 data for the following 35 iShares ETFs:
ACWV, CIU, CRED, CSJ, DVY, ECH, EEMV, EFAV, EFG, EFV,
EMB, FLOT, GVI, ICF, IDV, IEF, IEFA, IEI, IEO, IGE,
IGV, IJT, ITB, IUSG, IUSV, IYJ, IYT, IYZ, MBB, PFF,
REM, SHV, SHY, TUR, USMV.
It is also missing August 2 price data for ECNS and VQT.
None of these ETFs is exactly small.
It's curious. When you go to the price graphic for these funds, you would think there is no problem. Tuesday, August 1, exists, and Thursday, August 3, exists, and there is simply not a market day between these two dates.
