Manipulating the market can mislead others into making the wrong investment decisions.
Market manipulation could include making false or misleading statements and completing transactions that have the purpose of giving a false impression about supply or demand.
For example, market manipulation includes buying a large number of shares near the end of the day with the intention of driving the stock price to an artificial level.
Market manipulation also includes dissemination, which is when information that gives a false or misleading impression about an investment is spread. This artificially increases or decreases the stock price.
If fraud has been committed, report it to Action Fraud.
