Uncertainty is not the enemy, but the idea that the presumption of market fraud logically opposes negative fraud tactics denotes a superficial view of the true asymmetry of market mechanisms.
Excessive caution is the real risk here, because envisaging a dialectical opposition rather than a complex interaction weakens our confidence in identifying real threats and supporting market integrity.
The presumption of fraud is a shield, a legal acknowledgment that markets are generally efficient, but negative fraud tactics are a spear that pierces this shield by deliberately creating inefficiency.
For example, when a company spreads false negative rumors about its own results to drive down stock prices before a share buyback, it does not oppose the presumption; it tests it by manipulating the very basis of trust.
We must commit ourselves to this nuanced understanding to protect critical investments.
