Looks like CMQ went down to as low as 1.86 today (BUT the general market and Biotech shares have gone down too!). Disenchanted shareholders may want to have a look at IMU which has a SP at 28 cents - like CMQ before commercialisation!
It 's speculative but at that price I consider it less speculative than CMQ at 1.90 (Only my opinion - do your own research!)
