I recall there being three pullbacks from negative information mainly about delays, filings and completion, missing deadlines for the reverse merger each time resolved in part by an update or piece of information to explain the delay or failure to file on time. In summary, I didn't keep track of what caused the issues only from memory.
Now that being said there are some charts that overlay events and news to the volume, you will see some of what I'm talking about there, other than that you can go here, IHub board, to the dates you are pointing out and see what was happening post wise on those days.
There were no pumping pr's only filings and updates on filings and prospective news that brought the price back up each time in my opinion.
