Controlling what is controllable reveals that the direct opposition between the presumption of market fraud and negative fraud tactics is more contextual than logical.
The presumption of market fraud facilitates class actions, a post-facto correction mechanism rather than an active prevention of manipulative strategies.
Market discipline and regulatory oversight by entities like the Autorité des marchés financiers of Quebec are the true levers to counter these tactics.
Such opposition is weakened when regulators intervene proactively to identify and sanction market manipulation.
For example, a swift action by the OSC against allegations of false negative statements before a share buyback undermines the idea of a simple conceptual opposition.
