Low volume isn't it.
Broker data shows Australian retail (Comsec) by far the biggest sellers since the reverse split (net ~$500k). The biggest buyers by far are Ord Minnett and InstinetNomura (net ~$300k and ~$400k).
Paul Purcell (Sezzle director) is also buying a lot on market with another update overnight. He's bought almost AUD$500k in the last week.
So AU retail are selling and some important entities buying, ahead of the listing.
