Yes from $1.30 to $2.60 will be a double. $1.30 to $3.90 will be 200% gain.
But if you bought call option, yo may make much more.
I bought Octboer 2.50 call option at $0.20 last week. If stock up to $3.50 before October 17, the option will be worth at least $1.00, which is 500% gain. Theccall is at $0.45 now. Already gained 100%+.
