Knowing the structure makes the warning signs visible. This is written so you can avoid them.
Market manipulation means creating price or volume through artificial trading rather than real demand, then selling to people who came in on the appearance. It takes several forms: trading between colluding parties to make activity look genuine, placing and cancelling orders with no intent to fill them to distort the book, or spreading false information to induce buying.
A stock with little free float and normally quiet trading can be moved a long way with modest money. A heavily traded large stock resists the same amount. That is why the basic shape is an obscure stock suddenly surging without reason as volume explodes.
Cases differ but the visible shape repeats. Where several of the following overlap, keeping distance is the safe response.
An artificially raised price cannot hold once incoming money stops. Those who entered first sell while later entrants absorb that supply, so the later you enter the larger the loss. Across everyone who participated, this does not create value; it moves money from some participants to others.
Manipulation carries criminal penalties and fines in most countries, and liability can extend beyond the organisers to those who knowingly took part. Such stocks also frequently end in trading suspension or delisting, which removes the chance to sell at all. This piece explains the structure so it can be avoided and contains no judgement about any particular holding.
