Yes... I dont know if there was news or not to cause such a decline, however it looks like a typical "shake" of weak longs in the stock for the next run up. During the long wick candle on June 21 many technical indicators remained realitively strong, therefor supporting a bounce probability.
If you look closely at the next two candles you will find the 10 DMA then took on the position of resistance. It was not until the 3rd attempt it broke the 10 day moving average.
