Manipulation only works when you have a catalyst at the start or during relatively low volume periods. A deal after the meeting with substantial upfront money could cause return to double digits, not through manipulation but through strong buying. Not to say there will be no manipulation bringing it higher than it might go otherwise. In other words manipulators don't have 100% control of stock price 100% of the time. News vacuum, negative or positive catalyst provides opportunity to be additive to the movement in either direction.
