It sounds like that trade was a delayed trade, recorded after the close. This happens to many stocks, and it is usually associated with large orders that get filled over many smaller trades through the day. Typically institutional buying/selling on the big board stocks. There is no way to know where the market was during the trade, so it could be a buy or a sell. Either way, it's a huge position.
