After hours volume was 2900 shares. Sometimes (frequently) especially with small volumes, the after hours quote is really trades that, for whatever reason, werent reported during the trading day. There used to be a symbol (.sld? placed after the stock quote for sequence lag delay?) for out of order trade reports on the "tape", dont know what it is now if there is any..
To interpret "real" after hours action, it is better to use bid and ask, although typically the spread is much higher after hours.
