Zero Risk trade in AXP

AXP ER is tomorrow. The predicted market maker move is around $4. But looking at the chart we can say that if it beats chances are it will see 81.50 and if it misses it will go down to 71.90. My bias is more towards the downside. So I am going to buy Nov 77 puts for $1.90 and for insurance will also buy Nov 80 calls for 60 cents. Now if it beats and goes to 81.50 on Thursday, we will make $46/call but if it misses and goes to 71

.90, we will make $300/put
