Manipulation has been a major issue in securities markets for a long time. Manipulation can be defined as acts, which lure individuals to buy or sell a security. Manipulators send false signals to investors and deceive them. The main purpose of the manipulators is to make investors buy or sell certain securities based on these false signals and make a gain at the their expense. Manipulation is classified as action-based manipulation, information-based manipulation and trade-based manipulation (Allen and Gale, 1992). Another type of manipulation, which has emerged recently, is the financial information manipulation. In an action-based manipulation, manipulators take actions to deceive the investors. In an information-based manipulation, manipulators release false information or spread rumors for the same purpose. In a trade-based manipulation, manipulators engage in fraudulent trading to attract other investors.
Financial information manipulation is different from the rest. In this type of manipulation, information in the financial statements is distorted. Most of the investors base their investment decisions on the information contained in the financial statements. This information presents the financial position of a firm and the results of its operations. Profitability, liquidity, risk, earnings growth, etc., are basic information used in security analysis. This information must be fair and comparable. It must be free of misstatements (intentional or unintentional) so that it presents the financial position and the results of a firm's operations fairly in all respects. It must be comparable so that the prospects of different firms that issue securities can be assessed equally. |
