ok, finally got a time to read indeed the IV is a big component in the option price and it does go down big time after earning. Did some observation too. So the straddle strategy has not been working great for me but at least did not lose.I stopped reading as soon as you failed to mention implied volatility in buying a straddle. if you don't know what implied volatility is, its run up to earnings and collapse afterwards then stop trading and start reading.
I am contemplating about buying straddle several days before (not just a day before as I have been doing before) while IV is still reasonable low and then run up to earning day and sell it just before earning to see it will work.
