Uncertainty is not the enemy; considering the presumption of market fraud as fundamentally opposed to negative fraud tactics is an excessive simplification that lacks the conviction necessary. In reality, the presumption serves as a legal mechanism to address the consequences of these tactics, not as a contradictory concept. It is an attempt at justice in the face of manipulation, allowing investors not to have to prove individual reliance on each false statement when, for example, a company makes misleading statements to drop its stock price before a share buyback. It is about facilitating recourse in the face of information asymmetry, not a logical opposition.
