PrefaceThere is a bullish momentum pattern in CDNA stock 14 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 Bullish Option Trade Before Earnings in CareDx Inc (NASDAQ:CDNA)We will examine the outcome of getting long a monthly call option in CareDx Inc 14-days before earnings (using calendar days) and selling the call before the earnings announcement if and only if 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 analysis requirement -- note only one is "turned on," and that is the 50-day moving average requirement.:
If the stock price fails the technical requirement, it's fine, we just put a pin in it and check next quarter. Even better, we can set an intra day alert in Trade Machine that will email and/or text you when both requirements are met, just like this:
RISK MANAGEMENTWe can add another layer of risk management to the option trading 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 CareDx 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 9 pre-earnings attempts. In other words -- it's working.
We see a 193.1% return, testing this over the last 3 earnings dates in CareDx Inc. That's a total of just 42 days (14-days for each earnings date, over 3 earnings dates).
This is not a magic bullet, rather it's a bullish strategy. In the short-term it hasn't seen any losses, but more importantly, whether or not it loses on any given earnings run-up, the 193.1% return in less than two-full months of trading is predicated on an idea of consistent momentum.
Setting ExpectationsWhile this strategy had an overall return of 193.1%, the trade details keep us in bounds with expectations:
➡ The average percent return per trade was 102.3%.
