STXS has been going down for one reason only...private placement
as the Seeking alpha article said...he expects private placement from STXS. Which actually is a very good thing. Stock has been correcting for this, and is already accounting for this at current prices. It will be at 3.20 to 3.30 based on warrants pricing.
Look at Stellar...stock was at all time high, they did private placement, stock dipped for 1 DAY, now back to all time highs.
private placment is always new stock... dilution... in order to raise funds... especially for low flyers who are not blessed with pixie dust like Elon Musk companies of Solar City and Tesla. sometimes private placement is for mergers and acquisition finalizing... in order to pay bought out companies for their stock.
