Well when there was no news whatsoever, the stock went up to around $5.17. When there was finally news that first flight was going to take place, we are now at $4.87. Basically, if they do nothing, the price will go up and if they do something, people will jump in and short the living #$%$ out of it.
What will make this thing go up is if major airlines analyse the data received from their test flights and if they are all that they say they are, they will need to make concrete purchases. Air Canada said they were looking at replacing 100 planes and would make a decision by the end of the year. They were closely looking at BBD and the CSeries so if they are sold based on the data they will get from testing, their commitment would spike the stock up real nice with a huge order.
Be patient, disregard anything Chertsy will spew cause it isn't founded on anything, and wait for orders to come in. Then you will see results.
