The document describes three examples of market abuse: 1) An investment banker sells shares based on non-public financial information, using insider information. 2) A trader spreads false rumors on social media about a company's financial health, distorting the market value of its investments. 3) A group of traders manipulates the stock price of a company by coordinating buy orders to artificially increase demand and profit by selling at the inflated price, undermining the integrity of the market.
