Case Brief Summary & Legal Analysis
tl;dr: A financial printer traded on nonpublic information about upcoming corporate takeovers that he deduced from confidential documents. The Supreme Court overturned his securities fraud conviction, finding that he owed no duty to the sellers of the stock because he was not their fiduciary or a corporate insider.
Legal Significance: This case established the “classical theory” of insider trading liability under Rule 10b-5, holding that a duty to disclose or abstain from trading arises not from the mere possession of nonpublic information, but from a fiduciary or similar relationship of trust and confidence.

Case Facts & Court Holding
Key Facts & Case Background
Vincent Chiarella, an employee of a financial printing company, handled documents announcing corporate takeover bids. Although the names of the companies were concealed, Chiarella was able to deduce the identities of the target corporations before the information was made public. Based on this nonpublic information, he purchased stock in the target companies and subsequently sold the shares for a profit of approximately $30,000 after the takeover attempts were publicly announced. Chiarella had no connection to the target companies whose stock he traded. He was indicted and convicted for violating § 10(b) of the Securities Exchange Act of 1934 and SEC Rule 10b-5. The trial court instructed the jury that Chiarella could be convicted if he traded on material, nonpublic information without disclosing it. The Second Circuit Court of Appeals affirmed, reasoning that anyone who regularly receives material nonpublic information has an affirmative duty to disclose it before trading.
