The idea that the doctrine of market fraud inherently opposes negative fraud tactics is a simplification that masks the true operational asymmetry. This presumption offers a mechanism for post hoc recourse, not a proactive shield against initial manipulation. For example, an actor could deliberately depress a stock's price with false news before buying it back at a low price; the doctrine intervenes only after the damage, which is not a functional opposition. Such protection only materializes after proof of fault, thus leaving a window of opportunity for manipulations. Boldness and conviction are necessary to navigate these dynamics, as the market does not always protect investors by simple presumption.
