If counting from the lowest ($13.52) to highest ($2521), it is a move of 186-fold (18600%). I am not sure anything moved like this during the 2000 .com bubble period.
I hope you make money regardless, but you posted you borrowed shares. Did you short or not and did you cover and go long? Just curious but I would not touch this one at these levels.
Such incentive stock would be probably priced like $1 or 2 when issued to the employees, so if a person is granted $50000 incentive stock, 25000 share would be 4 or 5 millions now, and for a tech company that is the entry level of incentive stock reward.
Whoever holding at this price level should be very nervous and panicking watching the price gyrate any second. TO OUT OR NOT TO OUT, that is the question!
Normally people don't play this kind of crazy stock, but watching this over these days, I wonder if to allocate like 2% of the trading capital to such HKD thing, would it be a good idea?
