RE:complete left field thought here......@ Maritimedreamer : I think the contrary. Less shares = esier to manipulate (according that you have enough capital to do it). But the bottom point is how many shares are on the market. For example Tilry has around 90% of its shares in escrows** (80%) or in the hand of one compagny (10%) so it leaves only 10% out to deal. And a compagny that is manipulated right now and since is entrance in NY Stcok exchange mid-july 2018 is Tilray.
** Untill mid january2019 after that date, the owners will be able to sell if they wants so.
