it means nothing, actually back in the days of the big NTWK rally we started having pre hour and after hour small trades around 4$ while the stock was trading at 7,8,9 during the day. Sometimes a sign the stock is about to rally is if there is funny activity like this to try to fool people into selling. Why the bid is so much lower.. it might being the only after hours bid lowering it to scare people into selling. If you try to gather information form premarket trades.. you are likely going to get screwed. it's best to ignore it and pay attention to where the VOLUME happens. Because the only place the big boys can really trade efficiently is with good volume. So you know this is the price where they can do most of their buying and or selling.
