Trading 101 The Risks Of Trading Low-Volume Stocks http://www.investopedia.com/articles/active-trading/051415/risks-trading-lowvolume-stocks.asp Good luck
This was an official Nasdaq reopening print, and it was busted later that afternoon, along with some other trades that were far outside of the previous price. The stock's trading was chaotic apparently due to an announcement that the CEO would be presenting at a conference, and it was repeatedly halted and reopened. This type of scenario is not uncommon in development-stage biotech's.
I suspected it might be busted. Considering it was not an errant trade, but an actual opening auction, it's odd that that price even printed. The chaos comes from the fact that for small/micro caps , there are no liquidity providers.
