GrubHub Inc (NYSE:GRUB) : The Repeating Pattern in GrubHub Inc That Triggers Right After an Earnings Beat and The Option Trade That Follows

GrubHub Inc (NYSE:GRUB) stock soared on an earnings crush on Wednesday 7-25-2018 before the market opened, with the stock finishing up $25.67 or 23.54% to a new all-time high, by a lot. One day after 7-25-2018 would be 7-26-2018, near the close.

While this stock price is uncharted territory, the reaction off of a big earnings beat is not, nor is breaking through an all-time high off of that earnings report.

GrubHub Inc (NYSE:GRUB) Earnings

This just happened:

But if we take our focus away from the giant candle, and look backwards to the last two earnings releases before this one, circled in blue, we see two other gaps up off of earnings, which also both led the stock to all-time highs.

We can also see continued bullish momentum for a short window to follow. This won't work every time, there is no true silver bullet, but a pattern has persisted, and it has persisted for more than just this short time period.

In GrubHub Inc, if the stock move immediately following an earnings result was large (3% or more to the upside), if we test waiting one-day after that earnings announcement and then bought a three-week at the money (50 delta) call, the results were quite strong.

Here's the set-up of a more robust back-test:


* Condition: Wait for the one-day stock move off of earnings, and if it shows a 3% gain or more in the underlying, then, follow these rules:
* Open the long at-the-money call one-trading day after earnings.
* Close the long call 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 an upward trajectory after a large earnings move the two-weeks following earnings and it will stand to lose if the stock does not rise. 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.


Since blindly owning calls 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 call 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 rally 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.


If we bought the at-the-money call in GrubHub Inc (NYSE:GRUB) over the last three-years but only held it after earnings and after an earnings pop higher, we get these results:

Long 50 Delta Call

% Wins: 80%
Wins: 4 Losses: 1
% Return:  501.4%
