Cdiddy says there could be several various explanations for these trades that were displayed/revealed after the market closed, so he just ignores them....I agree with cdiddy. These large trades, "registered" after the market closed are probably (I've read) vwap's.....trades collected by an entity during the day, bundled as if they are one trade, and then activated always (usually???) at the end of the day. If these trades today (one for 300,000 shares and another for 500,000 shares) are not vwap's, then they would appear to be rather bullish indicators of large investors coming in.

How do I know they were last minute trades? They could have been earlier trades that were not "registered" until after the market closed? Market Makers add confusion to it all, entities collecting trades to trade as a bundle add confusion, opposing opinions from experienced people add confusion. Corruption and evil and immoral players, add confusion. So really I don't know much for certain. I know we unfortunately depend too much on what we read.
