judicial members were forced to interpret "on the fly" since Congress never gave a concrete definition. As a result, two theories of insider trading liability have evolved over the past three decades through judicial and administrative interpretation: the classical theory and the misappropriation theory. The classical theory is the type of illegal activity one usually thinks of when the words "insider trading" are mentioned. The theory's framework emerged from the 1961 SEC administrative case of Cady Roberts. This was the SEC's first attempt to regulate securities trading by corporate insiders. The ruling paved the way for the traditional way we define insider trading - "trading of a firm's stock or derivatives assets by its officers, directors and other key employees on the basis of information not available to the public." The Supreme Court officially recognized the classical theory in the 1980 case U.S. v. Chiarella. U.S. v. Chiarella was the first criminal case of insider trading. Vincent Chiarella was a printer who put together the coded packets used by companies preparing to launch a tender offer for other firms. Chiarella broke the code and bought shares of the target companies based on his knowledge of the takeover bid. He was eventually caught, and his case clarified the terms of what has come to be known as the classical theory of insider trading. However, the Supreme Court reversed his conviction on the grounds that the existing insider trading law only applied to people who owed a fiduciary responsibility to those involved in the transaction. This sent the SEC scrambling to find a way to hold these "outsiders" equally accountable. As a result, the misappropriation theory evolved over the last two decades. It attempted to include these "outsiders" under the broad classifications of insider trading. An outsider is a "person not within or affiliated with the corporation whose stock is traded." Before this theory came into existence, only people who worked for or had a direct legal relationship with a company could be held liable. Now casual investors in possession of sensitive information who were not involved with the company could be held to the same standards as CEOs and directors. This theory stemmed from a 1983 case, Dirks v. SEC, but the existence of the misappropriation theory had not been truly recognized until U.S. v. O'Hagan in 1995. The case - U.S. v. O'Hagan - involved an attorney at a Minneapolis law firm. He learned that a client of his firm (Grand Met) was about to launch a takeover bid for Pillsbury, even though he wasn't directly involved in the deal. The lawyer then bought a very sizable amount of Pillsbury stock options at a price of $39. After Grand Met announced its tender offer, the price of Pillsbury stock rose to nearly $60 a share. When the smoke finally cleared, O'Hagan had made a profit of more than $4.3 million. He was initially convicted, but the verdict was overturned. The case bounced around in the Court of Appeals for several years before it made its way to the Supreme Court. It is there the Supreme Court held that O'Hagan could be
