As a technical trader, I would say it looks like a very strong uptrend, forming a parabolic spike. No one can ever say how high a parabolic spike can reach, but they do tend to reverse suddenly downwards.
Capable momentum traders will cash in, the inexperienced will be crushed.
Disclosure - boxed (long one account, short an equal number of shares in another), biding my time until a downtrend is re-established.
