Here is how their methodology works:   In theory, if you knew exactly what price a stock would be immediately before earnings, you could purchase the corresponding straddle a number of days beforehand. To test this, we looked at the past 4 earnings cycles in 5 different stocks. We recorded the closing price of each stock immediately before the earnings announcement. We then went back 14 days and purchased the straddle using the strikes recorded on the close prior to earnings. We closed those positions immediately before earnings were to be reported.

    Study Parameters:

TSLA, LNKD, NFLX, AAPL, GOOG Past 4 earnings cycles 14 days prior to earnings - purchased future ATM straddle Sold positions on the close before earnings   The results: Future ATM straddle produced average ROC of -19%.   As an example:   In the previous cycle, TSLA was trading around $219 two weeks before earnings. The stock closed around $201 a day before earnings. According to tastytrade methodology, they would buy the 200 straddle 2 weeks before earnings. They claim that this is the best case scenario for buying pre-earnings straddles.
My Rebuttal 
  Wait a minute.. This is a straddle, not a calendar. For a calendar, the stock has to trade as close to the strike as possible to realize the maximum gain. For a straddle, it's exactly the opposite:
    When you buy a straddle, you want the stock to move away from your strike, not towards the strike. You LOSE the maximum amount of money if the stock moves to the strike.   In case of TSLA, if you wanted to trade pre-earnings straddle 2 weeks before earnings when the stock was at $219, you would purchase the 220 straddle, not 200 straddle. If you do that, you start delta neutral and have some gamma gains when the stock moves to $200. But if you start with 200 straddle, your initial setup is delta positive, while you know that the stock will move against you.    It still does not guarantee that the straddle will be profitable. You need to select the best timing (usually 5-7 days, not 14 days) and select the stocks carefully (some stocks are better candidates than others). But using tastytrade methodology would GUARANTEE that the strategy will lose money 90% of the time. It almost feels like they deliberately used those parameters to reach the conclusion they wanted.   As a side note, the five stocks they selected for the study are among the worst possible candidates for this strategy. It almost feels like they selected the worst possible parameters in terms of strike, timing and stocks, in order to reach the conclusion they wanted to reach.   At SteadyOptions, buying pre-earnings straddles is one of our key strategies.
