There's a totally legal type of insider trading and directors all the way up to the C-suite consistently beat the market, research finds

Insiders at multinationals, especially those in top positions, have an advantage due to their intimate knowledge of the company and its operations, resulting in higher returns. This raises concerns about fairness and the need for potential restrictions on insider trading.
