The previous (at least two) Earnings are followed by a much larger gap downwards with a low volume compared to the last one. This indicates a strong trend up, because the demand is much higher that before. Even the predicted earnings-short-trade didn’t pay off this time, cause by the huge demand. Also, the small price spread indicates huge transactions. If the down move is already over, then all those who are short and all swing-trader will buy. This can lead to strong up moves in the next days.
The trade from my post "Ausbruch nach oben" is still ongoing and the chance to reach the long-term is still high.
That’s my opinion and should be treated like it.
No trade advice!
