Lets put it simply in this way...IMHO, what did happen last week with that share price spike, would have had to be the biggest and best PUMP and DUMP that I could have ever seen. Unfortunately though, many didn't see it coming and possibly they are now left licking their wounds.
A drop of nearly 15% of the share price values in a day, is not something to be joyful and happy about it, while not totally unexpected IMHO.
