RE:RE:GMP bought most of the shares of today, about 6mGMP is lead underwriter for VXS IPO. They are not the ones buyinh/selling. They are helping to do block trades.
VXS has been around for 10+ years. My guess is that some old investors are getting out and new ones coming in. (6 month lock up expired yesterday). Since price is going up today these block trades are "buys". Good for stock.
