It's pretty common to see stocks get pumped up by people in advance of capital raisings, obviously raises the VWAP and makes a stock seem more attractive and hyped if its rising. I'm not saying for sure this is the case here as it could just be there's low supply. In any case the share price performance has been exceptional and I'm certainly not complaining.
I might also add that the mother company BLA has moved up quite powerfully too so it could also just be a bit of a flow on effect for those looking to get exposure to this company.
