Manipulation

The act of artificially inflating or deflating the price of a security. In most cases, manipulation is illegal. It is much easier to manipulate the share price of smaller companies, such as penny stocks, because they are not as closely watched by analysts as the medium- and large-sized firms.

Also known as "price manipulation".

Investopedia Commentary

One way people can deflate prices is by placing hundreds of small orders at a significantly lower price than what it has been trading. This gives investors the impression that there is something wrong with the company, so they sell, pushing the prices even lower. Another example of manipulation would be to place simultaneous buy and sell orders through different brokers that cancel each other out, but give the perception that because of the higher volume there is increased interest in the security.
