OK, I'm putting down the crack pipe while posting. The idea was good, but the examples were pure crap.
So, let's try BABA Dec. 20 (2 weeks) 106/107 call debit for -.60 and a 116/117 call debit for -.10
(I'm using stale yahoo quotes from Friday, prices are approx midpoint. )
P/L -10% L=-.70, Unchanged (107.90) P=.+20, +10% P= +130 about the same as OP's trade.
This is what I get for posting on the run
EDIT: You could use the 107/108 call debit for better results given the criteria.
You do realize that this is a discussion based on the parameters posed in the OP? It is not an actual trade. What the realized prices (fills) and costs would be, depends on how the position is acquired(order entry).What is the "actual" P/L after taking into account commissions and slippage ?
Sometime KISS is better, a pure debit spread will do the same job.
