In securities litigation, the motion to dismiss is the case
Two thirds of federal securities class actions that survive the pleading stage settle. The brief that decides which side of that line you fall on is written in the first ninety days.
The Private Securities Litigation Reform Act stays discovery while a motion to dismiss is pending. That single procedural fact restructures the entire economics of a securities class action. If the motion is granted, the defendant has spent a fraction of what a discovery-phase settlement would have cost. If it is denied, the cost of continuing usually exceeds the cost of settling, and both sides know it.
Everything a defense team does in the first ninety days should therefore be in service of that one brief.
Hire the economist before the lead plaintiff is appointed
Loss causation is an empirical question. Did the corrective disclosure actually move the price, controlling for market and sector movement on the same day, and was the movement statistically significant? A complaint that alleges a decline without that analysis is vulnerable, but only if the defense brief does the analysis.
Retaining an event-study economist in the first weeks costs relatively little and frequently produces the strongest paragraph in the motion. Waiting until class certification means arguing materiality with adjectives while the plaintiff argues it with data.
Scienter is pleaded holistically, so defend it holistically
Courts assess the complaint’s inferences as a whole against the competing innocent inference. That means the defense cannot simply dismantle each allegation in isolation. The brief needs an affirmative narrative: a coherent, documented account of what management actually knew and when, which is more compelling than the plaintiff’s account of concealment.
A motion to dismiss that only attacks is weaker than one that also explains. Judges are choosing between two stories.
Use the safe harbour precisely
Forward-looking statements accompanied by meaningful cautionary language are protected, but boilerplate risk factors that did not change as the risk changed are not meaningful. The quality of the safe-harbour argument is decided long before litigation, in how carefully the risk factors were maintained quarter to quarter.
What this implies before there is a case
Disclosure practice is litigation preparation. Risk factors that are revised when the business changes, internal documents that reflect the same view of the facts as the public filings, and a documented disclosure committee process are worth more at the pleading stage than any argument counsel can construct afterwards.
