The way I understand how after hour trades are reported, is sequentially, with the share price being reported as the last trade. There was over 500,000 block trading at 2.55. The last trade was a 1,000 shares at 2.48. The share prices reported is the last trade, although it is only 1000 shares out of the 933,000 traded.
I am not an after hours trader, an have no real interest in AF numbers, but someone please enlighten me.
