I thought the same thing so jumped in yesterday, but back out again today at no profit just bokerage.
Was hoping that the AHF buying might draw in some liquidity but it hasn't really - probably a long term play. Same chairman of both companies so I don't doubt in the long run it will do well. Just a matter of whether you want to get your money out in a short period.
There is (was) an offscreen seller there at 18c that filled my order yesterday if people really want to get in.
