Buy @ $2.21
Very illiquid with big buy/sell gap, easier to get during pre-open or pre-close. The risk-reward on first look, is rather unattractive. If the Nan Fung deal fails, it'll likely drop back to ~$1.60 ie. -60ct and if it goes thro', it'll rise towards $2.98 (what Nan Fung will pay for their stake) ie. +70ct+. Any bet therefore hinges on whether this Nan Fung deal has a high probability of failure or success…
I'm betting that the chances of success is a lot more than 50% (refer to VB forum for more info on Forterra and Nan Fung as there're good info and links there). Will likely continue to nibble on further drops – likely to happen if the deal drags and chances of success starts to fade… 😀
