BJ's Restaurants Inc (NASDAQ:BJRI) : The One-Week Pre-earnings Momentum Trade With OptionsDate Published: 2017-10-16
There is a bullish momentum pattern in BJ's Restaurants Inc (NASDAQ:BJRI) stock 7 calendar days before earnings, and we can capture that phenomenon explicitly by looking at returns in the option market. The strategy won't work forever, but for now it is a momentum play that has not only returned 107.6%, but has also shown a win-rate of 75%.
The logic behind the test is easy to understand -- in a bull market there can be a stock rise ahead of earnings on optimism, or upward momentum, that sets in the one-week before an earnings date.
That is, totally irrespective of the reality that follows -- that is, independant of whether the stocks have a history of actually rising after earnings. There has been a way to profit from this pattern without taking any formal earnings risk in BJ's Restaurants Inc.
The Bullish Option Trade Before Earnings in BJ's Restaurants Inc
We will examine the outcome of getting long a weekly call option in BJ's Restaurants 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.
