Lets say you want to make a play on oracle's post earning move. Which is the better atm strangle to buy? DEC18 31C IV=52 vega=0.01 $0.4 DEC18 30P IV=58 vega=0.01 $0.4 vs JAN22 31C IV=26 vega=0.04 $0.8 JAN22 30P IV=28 vega=0.04 $0.85 I am thinking Jan's combo, even though it has higer vega and twice as expensive, the Dec combo with double the IV and <2day expiration will lose its value right post earning where as Jan will still retain most of its values since its IV is much lower. I guess it's a question of vega vs IV? what are your thoughts?
