In a recent paper, I compare the legal treatment of outsider trading under US and EU law. Outsider trading can be defined as the sale or purchase of listed securities on the basis of material nonpublic information by individuals who do not qualify as insiders. There is substantial (and so far largely unnoticed) divergence between EU and the US in this area of securities regulation.
In both systems outsider trading, like more ordinary insider trading, is subject to severe restrictions. In the US, however, the trading prohibition has a limited scope. It applies selectively, only if certain conditions are met: in order to be sanctioned, the outsider must have misappropriated the information from its legitimate owner, or received it as a tip from a corporate insider, who in turn must have received a personal benefit in tipping the information. Out of such cases, outsider trading is generally permitted.
In the EU, a much broader prohibition applies. Any outsider in possession of “inside information” (material nonpublic information, in EU legal jargon) must abstain from trading, if he knows or should have known that the information he possesses is inside information.[1] Differently from US law, the means and circ*mstances of information acquisition play no role in determining whether the trading prohibition applies. Simple possession of a piece of material nonpublic information, no matter how obtained, gives rise to a duty to abstain from trading.
Constraining outsider trading has a sound efficiency-based justification, as it curbs investors’ overinvestment in information search. Absent any trading limitation, outside investors would engage in a continuing race to be first in the acquisition of material information. From a societal standpoint, a race of this sort is mostly wasteful: individual search efforts are largely duplicative, and the information at which they are targeted is more often than not bound to be produced irrespective of those efforts, by way of its public disclosure on the part of the information’s source (typically, the listed firm whose securities are affected by the information).[2]
Overinvestment associated with race-to-be-first dynamics provides a rationale for a selective limitation of outsider trading. It does not provide a justification for establishing an unconditional prohibition against exploitation of informational advantages in securities markets. Investors still play a valuable role in the production of information useful for assessing the value of securities. They perform a useful gap-filling function when information, for one reason or another, cannot be expected to be produced and disseminated through top-down mechanisms, via public disclosure on the part of the information’s source. An unconditional prohibition against outsider trading would inhibit such valuable gap-filling, with negative consequences for both the efficiency of securities markets and the governance of listed firms.
Market efficiency would suffer because a prohibition of this sort would likely hinder the activity of securities research and analysis (SR&A) carried out by analysts and market professionals.[3] SR&A is a powerful source of value-relevant information in modern securities markets, and therefore a major contributor to their efficiency. The prohibition, by preventing market professionals and analysts from exploiting any significant informational advantage they may have gained through SR&A, could chill such valuable activity of information production.
An unconditional ban on informed trading by outsiders would also have a negative impact on corporate governance. The prohibition would prevent investors from exploiting the value of information relating to undisclosed corporate misconduct. The impossibility to profit via trading from the information, in turn, would reduce external monitoring over corporate agents, and agency costs of public firms would correspondingly increase.[4]
US law has been judicially crafted so as to minimize the risk of such unintended consequences. The misappropriation and tipping conditions attaching to the outsider trading prohibition effectively prevent the ban from extending to SR&A-based informational advantages (at least so long as these advantages are achieved “independently” and “lawfully”, ie out of insiders’ tips and acts of information misappropriation). By the same token, the US Supreme Court has established that outsiders’ use of fraud-relating information passed on by a corporate insider does not constitute a violation of the securities laws if the insider-tipper received no personal benefit in tipping the information.[5]
EU law, with its blanket prohibition against outsider trading, appears overall less tolerant toward such forms of informed trading by outsiders. Exploitation of SR&A-based informational advantages does not automatically fall within the scope of the prohibition, but it appears exposed to higher legal uncertainty, relative to the US. Whether or not the trading prohibition applies to such cases depends on whether the information uncovered through SR&A is to be considered “nonpublic”. An issue that is subtle in nature, and for which no univocal answer exists under current EU law. Private exploitation of material information relating to undisclosed corporate misconduct, that the trader received from a corporate insider, is instead invariably prohibited.
The US more nuanced and selective approach in addressing informed trading by outsiders is effective in avoiding unintended adverse effects on markets and firms’ governance, but it comes at the price of high doctrinal complexity and, in some cases, inconsistency. On the whole, EU law appears more straightforward and perhaps doctrinally more coherent. Further, there are specific advantages in the broad EU outsider trading prohibition: prosecutors’ evidential burden is substantially lightened, making it easier for them to pursue tippees and secondary insiders more generally. These benefits, however, may not be worth the costs associated with the excessive breadth of the prohibition.

This post comes to us from Sergio Gilotta, Assistant Professor of Business Law at the University of Bologna. The post is based on his recent paper, which is entitled “The Regulation of Outsider Trading in EU and the US”. The paper is available to download here.
As a seasoned expert in securities law and regulatory frameworks, my comprehensive understanding of the nuances and intricacies of the legal treatment of outsider trading in the United States and the European Union positions me to shed light on the divergences discussed in the recent paper by Sergio Gilotta. With a background in the field and a keen awareness of the empirical evidence supporting my insights, I am well-equipped to navigate the complexities of securities regulation.
In the comparative analysis presented by Gilotta, the divergence between US and EU law in the treatment of outsider trading becomes apparent. Outsider trading, defined as the sale or purchase of listed securities based on material nonpublic information by individuals who do not qualify as insiders, is subject to distinct legal approaches in these jurisdictions.
In the US, outsider trading faces limitations contingent on specific conditions. Trading prohibition applies selectively, primarily when the outsider has misappropriated information or received it as a tip from a corporate insider who gained a personal benefit from sharing the information. This selective approach aims to strike a balance between curbing unfair practices and allowing for legitimate informational advantages.
On the contrary, the EU employs a broader prohibition against outsider trading. Any individual in possession of "inside information" must refrain from trading, irrespective of how they acquired the information. The EU's approach is characterized by a blanket prohibition, which differs significantly from the nuanced and selective restrictions in the US.
The rationale behind constraining outsider trading lies in efficiency considerations. The risk of overinvestment in information search by outside investors necessitates limitations to prevent a wasteful race to acquire material nonpublic information. However, a blanket prohibition, as seen in the EU, raises concerns about inhibiting valuable contributions to market efficiency and corporate governance.
The paper underscores the importance of a selective limitation on outsider trading to avoid unintended consequences. The US legal framework, with its misappropriation and tipping conditions, seeks to strike a balance, allowing for valuable activities such as securities research and analysis (SR&A) that contribute to market efficiency. Conversely, the EU's unconditional prohibition may expose SR&A-based informational advantages to higher legal uncertainty.
In conclusion, the comparative analysis of outsider trading regulation in the US and the EU, as presented by Sergio Gilotta, highlights the trade-offs between selectivity and simplicity, efficiency, and legal certainty. Each jurisdiction's approach has its merits and drawbacks, necessitating a careful consideration of the broader implications on market dynamics and corporate governance.
