Option trading isn't about luck -- this three minute video will change your trading life forever: Option Trading and Truth
By definition trading options during earnings is very risky. But, once we step into that world, in turns out that there is a lot less 'luck' involved in successful option trading than many people have come to understand.
We can get specific with long earnings strangles for SFBS in this dossier. Let's look at a one-year back-test of a long 20 strangle only held during earnings. Here are the rules we followed:
* Test monthly options, which means we are not trading the weekly options (we could so if we chose).
* Only hold the position during earnings. Specifically, we test initiating the position two-days before the earnings event, then hold through earnings, and then close two-days after.
* Test the out of the money strangle -- specifically the 20 delta strangle.
* Test the earnings strangle looking back at one-year of history.
More than all the numbers, we simply want to walk down a path that demonstrates that it is actually quite easy to optimize our trades with the right tools. In the set up image below we just tap the rules we want to test.
Next we glance at the returns.

Rather remarkably, we note that the long strangle strategy actually produced a higher return than the stock 17.5% versus 60.3% or a -42.8% out-performance. That means a strategy that was held, in total, for about a month outperformed the stock held for the last one-year.
An earnings event is really just a volatility event that we know is coming ahead of time. What we're really analyzing here is if, historically, the option market has priced the implied stock move too high or too low.
In this case, the option market's implied vol has been lower than the actual stock movement. We can see that a long strangle and only holding the position during earnings in ServisFirst Bancshares Inc returned 17.5%. But, there's a much bigger picture here. Let's turn to that piece, now.
