If you're already on top of volatility and the impact it has on option trading and earnings -- let's get going.

We want to introduce how easy this is with the right tools but also how important it is to make sure you use them. Just tap the appropriate settings.
And now the findings.

That first step of analyzing a short straddle while avoiding earnings is nice -- but let's go deeper.
Let's look at the same analysis, but we will only look at earnings. Specifically, we will short the straddle two-days before earnings, then close the option position two-days after earnings.

Here are those results for the same short straddle:
short 50 Delta Straddle | ||||
* Trade Frequency: 30 Days | ||||
* Back-test length: three-years | ||||
* Only Trade Earnings | ||||
Gross Gain: | $2,888 | |||
Gross Loss: | -$457 | |||
Wins: 10 | Losses: | 2 | ||

Selling an uncovered straddle in Group 1 Automotive Inc during earnings proved to be a big winner, more importantly, it returned more than the same short straddle that avoided earnings. While this clever use of earnings has outperformed the short straddle that avoided earnings, the question of risk is still in play. Having an option position during earnings is one of the riskiest implementations possible. The point is not that earnings were so strong -- there's a bigger picture here.
Having historical analysis in hand before option trading maps the decision process about what to trade, when to trade, and even if the trade is worth it at all. Now let's go beyond Group 1 Automotive Inc and trading short straddles to something that makes a difference in our trading lives.
