The strategy won't work forever, but for now it is a momentum play that has not only returned 157%, but has also shown a win-rate of 58%.

The Bullish Option Trade Before Earnings in Amazon.com Inc
We will examine the outcome of getting long a weekly call option in Amazon.com Inc 7-days before earnings (using calendar days) and selling the call before the earnings announcement.
Here's the set-up in great clarity; again, note that the trade closes before earnings, so this trade does not make a bet on the earnings result.
We can add another layer of risk management to the back-test by instituting and 40% stop loss and a 40% limit gain. Here is that setting:
In English, at the close of each trading day we check to see if the long option is either up or down 40% relative to the open price. If it was, the trade was closed.
Here are the results over the last three-years in Amazon.com Inc:
We see a 157% return, testing this over the last 12 earnings dates in Amazon.com Inc. That's a total of just 84 days (7-days for each earnings date, over 12 earnings dates). This has been the results of following the trend of bullish sentiment into earnings while avoiding the actual earnings result.
We can also see that this strategy hasn't been a winner all the time, rather it has won 7 times and lost 5 times, for a 58% win-rate and again, that 157% return in less than six-full months of trading. The trade will lose sometimes, but over the most recent trading history, this momentum and optimism options trade has won ahead of earnings.
While this strategy had an overall return of 157%, the trade details keep us in bounds with expectations:
➡ The average percent return per trade was 12.36%.

Now we can look at just the last year as well:
We're now looking at 66% returns, on 3 winning trades and 1 losing trades. It's worth noting again that we are only talking about one-week of trading for each earnings release, so this is 66% in just 4-weeks of total trading which annualizes to 860%.
➡ The average percent return over the last year per trade was 16.73%.
Bullish momentum and sentiment ahead of earnings can be a repeating pattern in a bull market for some companies. This is just one example of what has become a tradable phenomenon in Amazon.com Inc.
