The wait for the FDA approval is not helping.
People get nervous that it is taking longer than expected and start to worry that there may be problems so the price drops.
Then a rumour or speculation spreads that the approval is imminent so people buy rather than miss out on the upside when the approval is announced.
The fluctuations will continue until something definite is said about the approval.
I hope it's soon.
