Whether a securities-fraud plaintiff can prove loss causation merely by showing that the defendant's misrepresentation inflated the security's price at the time of purchase.
Holding
No. An inflated purchase price alone neither constitutes nor proximately causes the economic loss required for a private action under § 10(b) and Rule 10b-5.
Reasoning
In a fraud-on-the-market case, paying an inflated price does not itself establish a loss at the moment of purchase. The buyer's payment is offset by ownership of stock with an equivalent market value at that time. An actionable claim requires both economic loss and a causal connection between the misrepresentation and that loss.
A later decline in the stock's price does not necessarily result from the earlier fraud. The investor may sell before the truth reaches the market, or the later decline may stem from changing market conditions, investor expectations, industry developments, or company-specific events unrelated to the misstatement. Thus, purchase-price inflation may be related to a later loss, but merely "touching upon" a loss is not the same as causing it.
The Court's conclusion accords with the common-law roots of the implied securities-fraud action. Common-law deceit requires actual pecuniary damage proximately caused by the fraudulent statement, and other circuits had likewise rejected the view that inflation at purchase, standing alone, satisfies loss causation.
The Private Securities Litigation Reform Act confirms that result. It expressly places on the plaintiff the burden to prove that the defendant's act or omission caused the loss for which the plaintiff seeks recovery. Permitting recovery solely because a purchase price was inflated would improperly turn federal securities law into insurance against ordinary market losses rather than a remedy for losses fraud actually caused.
