Question 1: Is the average return for DexCom stock higher after a drop?
Consider two situations,
Case 1: DexCom stock drops by -5% or more in a week
Case 2: DexCom stock rises by 5% or more in a week
Is the average return for DexCom stock higher over the subsequent month after Case 1 or Case 2?
DXCM stock fares better after Case 1, with an average return of 3.4% over the next month (21 trading days) under Case 1 (where the stock has just suffered a 5% loss over the previous week), versus, an average return of 3.2% for Case 2.

Question 3: What about the average return after a rise if you wait for a while?

Interestingly, though, if a stock has gained over the last few days, you would do better to avoid short-term bets for most stocks - although DXCM stock appears to be an exception to this general observation.
