Which of the following actions could lead to market abuse?

Deliberately spreading false information is a clear example of market abuse as it undermines the integrity of the financial markets. This action can distort the true value of securities, mislead investors, and create an uneven playing field for market participants. When false information is disseminated, it can lead to manipulated trading behavior, where investors make decisions based on inaccurate or misleading data, ultimately harming the market's fairness and transparency.

In contrast, distributing trade reports, conducting annual financial reviews, and organizing investor meetings are legitimate activities that promote transparency and information sharing among market participants. These actions help investors make informed decisions based on accurate and relevant information, thus supporting the market's integrity rather than undermining it.
