When a publicly traded company is exposed for misleading practices, its stock price falls by more than 60% within a few months.
Mechanism
Synthesis from 3 studies
When a company is caught lying, investors stop believing its promises and rush to sell their shares. This flood of selling crashes the stock price fast. Some investors might also sell because they expect fines, but the main driver is loss of trust.
Most probable mechanism
When a company is exposed for lying about its practices, investors lose confidence and sell their shares all at once, causing the stock price to drop sharply.
Public exposure of deceptive corporate behavior reduces perceived credibility of the company's financial and operational disclosures
Reduced credibility causes institutional and retail investors to reassess the company's future cash flow expectations
Reassessment leads to synchronized selling pressure across trading platforms
Synchronized selling overwhelms buy-side liquidity, causing rapid price depreciation
Less supported by current evidence, but not ruled out
When deceptive practices are revealed, investors anticipate future fines or legal action and sell shares before regulators act.
Public disclosure of misconduct triggers expectations of regulatory intervention
Investors liquidate positions to avoid anticipated future losses from penalties or operational restrictions
