The latest AQB quote I see on nasdaq.com is $24.00, but this price may be an artifact insofar as today is the first day of Nasdaq trading and the ABTU.L closing price today (on the AIM/London exchange) was 1400 GBp, which equates to $17.27 at the current exchange rate. If the $24.00 Nasdaq price is legitimate, then AQB's current enterprise value is about $140M.
It has come back down to the levels the couple days as AQBTV before opening on NASDAQ as AQB. Still unclear what kind of position I will take but will grab a very small starter in here somewhere with price around 16.00 or so.
It may take a few weeks or more to establish a somewhat stable valuation - with the low float and low volume the term "stable" is fairly relative!
