It makes little sense of the selling, but then each investor has their own individuality in regards to selling and or buying. I would have imagined that if you were an investor you would have sold before the split, not after it.
Of course their was a lot of paper out going. Could be agents selling their fee payments. Whatever the reason, sure going to take some healing time. One can only guess going forward. For an investor it would be a personal crime to be buying not having a few quarters of some healthy financials on the record.
