Many of the people who held warrants sold half their warrants to fund the exercise price, making a cost basis on CCME of like 0 (Plus what they paid for the warrant =P).
So if you bought the warrants at say $1 average (some got in lower), that means the current price of $20 (divided by 2 since you had to sell half the warrants to fund the exercise price) gives you $10.
So cost of $1, current "equivalent price" of $10...10 bagger ;).
Of course, if your average warrant cost was $0.50, thats a 20 bagger ;).
