There is something "off" regarding the SP close listed yesterday. For some reason, all of the juniors that I follow, had a listed SP close on the TSX-V which was higher than the actual close. Thus, it appears that these same juniors have had significant SP drops today.
For example, NOT was listed as having a close of $0.59, but I believe that it in fact had a close of $0.51 yesterday on the TSX-V. Thus, at today's SP of $0.53, it is actually up 2 cents, rather than down 6 cents.
It may be that yesterday the SP close listed was that on one of the other exchanges (there are 8 different ones listed on the TSX website ( http://web.tmxmoney.com/quote.php?qm_symbol=not ) see Canadian Consolidated Montage .
I am not sure why there has been this discrepancy, perhaps others here have more insight.
