PrefaceThere is a bullish momentum pattern in Enanta Pharmaceuticals Inc stock 7 calendar days before earnings. Further, we use moving averages as a safety valve to try to avoid opening a bullish position while a stock is in a technical break down, like the fourth quarter of 2018. The strategy won't work forever, but for now it is a momentum play that has not only returned 225.5%, but has also shown a win-rate of 71%.
This same strategy also worked in the throes of the bear market from 2007-2008, and we discuss those results near the finale of this article.
LOGICThe logic behind the option trading backtest is easy to understand -- in a any 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 phenomenon has been well documented by Capital market Laboratories in our seminal webinar on market patterns.
That is, totally irrespective of the reality that follows -- that is, irrespective 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 Enanta Pharmaceuticals Inc.
The Bullish Option Trade Before Earnings in Enanta Pharmaceuticals Inc (NASDAQ:ENTA)We will examine the outcome of getting long a weekly call option in Enanta Pharmaceuticals Inc 7-days before earnings (using calendar days) and selling the call before the earnings announcement if and only if this technical analysis condition is met: the stock price is above the 50-day simple moving average.
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.
And here is the technical requirement -- note only one is "turned on," and that is the 50-day moving average requirement.:
Here's a visual representation, where the stock price 7-days before earnings (circled) is above the 50-day moving average (black line), and therefore triggers a back-test.
If the stock price fails the technical requirement, it's fine, we just put a pin in it and check next quarter.
RISK MANAGEMENTWe 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.
RESULTSHere are the results over the last three-years in Enanta Pharmaceuticals Inc:
The mechanics of the TradeMachine® stock option backtester are that it uses end of day prices for every back-test entry and exit (every trigger).
Notice that while this is a 3-year back-test and we would expect four times that many earnings triggers (4 earnings per year), the technical requirement using the 50-day moving average has avoided 5 pre-earnings attempts. In other words -- it's working.
We see a 225.5% return, testing this over the last 7 earnings dates in Enanta Pharmaceuticals Inc. That's a total of just 49 days (7-days for each earnings date, over 7 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 5 times and lost 2 times, for a 71% win-rate and again, that 225.5% 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.
Setting ExpectationsWhile this strategy had an overall return of 225.5%, the trade details keep us in bounds with expectations:
➡ The average percent return per trade was 41.18%.

Is This Just Because Of a Bull Market?
It's a fair question to ask if these returns are simply a reflection of a bull market rather than a successful strategy. It turns out that this phenomenon of pre-earnings optimism also worked very well during 2007-2008, when the S&P 500 collapsed into the "Great Recession."
The average return for this strategy, by stock, using the Nasdaq 100 and Dow 30 as the study group, saw a 45.3% return over those 2-years. And, of course, these are just 8 trades per stock, each lasting 7 days.
