1. Prohibited Conducts
1.1 Under Section 176 Stock Price Manipulation, no person shall effect, take part in, engage in, be concerned in, or carry out, either directly or indirectly, any number of transactions in securities of a corporation, being transactions that have, or are likely to have, the effect of–
(a) raising;
(b) lowering; or
(c) pegging, fixing, maintaining or stabilising,
the price of securities of the corporation on a stock market in Malaysia, for the purpose which may include the purpose of inducing other persons, whether or not another person is induced, to acquire or dispose of the securities of the corporation or of a related corporation.
1.2 Under Section 177 False or misleading statements, A person shall not make a statement, or disseminate information, that is false or misleading in a material particular and is likely to induce the sale or purchase of securities by other persons or is likely to have the effect of raising, lowering, maintaining or stabilising the market price of securities if, when he makes the statement or disseminates the information–
(a) he does not care whether the statement or information is true or false; or
(b) he knows or ought reasonably to have known that the statement or information is false or misleading in a material particular.
One example is "Pump and dump", a form of stock fraud that involves artificially inflating the price of an owned stock through false and misleading positive statement in order to sell the cheaply purchased stock at a higher price. Once the operators of the scheme "dump" their overvalued shares, the price falls and investors lose their money.
2. Insider trading
Under Section 188 Prohibited conduct of person in possession of inside information. A person is an “insider” if that person possesses information that is not generally available which on becoming generally available a reasonable person would expect it to have a material effect on the price or the value of securities; and knows or ought reasonably to know that the information is not generally available.
The insider shall not, directly or indirectly, communicate the information referred to in subsection (1), or cause such information to be communicated, to another person, if the insider knows, or ought reasonably to know, that the other person would or would tend to–
(a) acquire, dispose of, or enter into an agreement with a view to the acquisition or disposal of, any securities to which the information; or
(b) procure a third person to acquire, dispose of or enter into an agreement with a view to the acquisition or disposal of, any securities
Therefore insider trading violations include "tipping" such information and securities trading by the person "tipped" based on these exclusive information. For example, a forumer might claim he has exclusive information that actions by directors/officers of public listed companies, actions by syndicates or even actions by ministers or people related to ministers will soon impact a particular security price. As he start to tip everyone else by via public posts or PM, he'd already infringed the law.
