LEDEThere is a bearish momentum pattern in Alphabet Inc (NSDQ:GOOGL) stock 1 trading day after earnings, if and only if the stock showed a large gap down after the actual earnings announcement.
This is a conditional entry -- the company reports earnings and if the stock move off of that report is a 3% loss or larger, then a bearish position is back-tested looking for continuing downward momentum. The event is rare, but when it has occurred, the back-test results are noteworthy.
Alphabet Inc (NSDQ:GOOGL) Earnings
In Alphabet Inc, if the stock move immediately following an earnings result was a large drop (3% or more to the downside), when we test waiting one-day after that earnings announcement and then bought a three-week at the money (50 delta) put, the results were quite strong.
This back-test opens one-day after earnings were announced to try to find a stock that continues a downward spiral after an earnings gap down.
Simply owning options after earnings, blindly, is likely not a good trade, but hand-picking the times and the stocks to do it in can be useful. We can test this approach without bias with a custom option back-test. Here is the timing set-up around earnings:
Rules* Condition: Wait for the one-day stock move off of earnings, and if it shows a 3% loss or more in the underlying, then, follow these rules:
* Open the long at-the-money put one-trading day after earnings.
* Close the long put 14 calendar days after earnings.
* Use the options closest to 21 days from expiration (but more than 14 days).
This is a straight down the middle direction trade -- this trade wins if the stock is continues on a downward trajectory after a large earnings move the two-weeks following earnings and it will stand to lose if the stock rises, instead. This is not a silver bullet -- it's a trade that needs to be carefully examined.
But, this is a conditional back-test, which is to say, it only triggers if an event before it occurs.
RISK CONTROLSince blindly owning put can be a quick way to lose in the option market, we will apply a tight risk control to this analysis as well. We will add a 40% stop loss and a 40% limit gain.
In English, at the close of every trading day, if the put is up 40% from the price at the start of the trade, it gets sold for a profit. If it is down 40%, it gets sold for a loss. This also has the benefit of taking profits if there is a stock decline early in the two-week period rather than waiting to close 14-days later.
Another risk reducing move we made was to use 21-day options and only hold them for 14-days so the trade doesn't suffer from total premium decay.
Here are the results of a long at-the-money put in Alphabet Inc (NSDQ:GOOGL) over the last three-years but only initiated after earnings if the stock dropped by 3% or more:
